Keeping both signals in phase is an additional constraint !  ;-)

Then again, since your end result is an FFT per sec, you could use a 1s timer to trigger the start of processing both stored/accumulated signal "1 sec slices" to get your FFT result.  With today's multi-Mega-samples/s processing speeds, a single DSP chip could have enough "humpf" to pull it off... but within your IC price budget ?  TBD.

 

Iron

Yes, StephT, that was my assessment, too. With DSP chips or even and RTOS system, you have to round robin the samples.  If you want to keep the vibration or audio samples in phase, you need to have concurrent processing in an SOC.

Gold

Although sampling period does not affect the number of bits you need in the processing chain... but the time you have to "chump" the bits

Iron

forgot time, how long is sampling time.

Here's a lead

http://en.wikipedia.org/wiki/Analog_to_digital_conversion

gotta fly

Iron

input(s) x bit depth x sampling rate and extra for meta data. storing bytes, word,s double words, etc is another consideration

Iron

@78RPM :Good luck!  Have fun

Iron

In FPGAs, you could have 2 streams processing in real-time and do with much less RAM (ongoing processing of the sample stream) ; with DSP chips, you'll have to time-share the processing meaning storing the samples while the other stream gets processed...

Iron

Yes, it's fast.  Good considerations on RAM. I have to sign off now.  Bye.

Gold

1s ; that's (relatively) pretty fast ; would need to re-check DSP theory to get a feel for how much RAM (to store the samples in the FFT topology) you'd need to store results...  You could also look up Wikipedia for some pointers !  ;-)

 

Iron

Thank you so much,  Charles for this valuable clarification and lecture

Iron

Right, Nyqust frequency. I'll take your suggestions from here.

I need the results back in less than 1 second so that servos could act upon the info.

Gold

how fast do you need your FFT results back ?

Iron

so 5kHz vibration =  10kHz (min) sampling rate

so 20 kHz audio = 40 kHz (min) sampling rate

Iron

Yes, I need to take several signals (audio, vibration) and simultaneously process them in parallel and get them to the frequency domain. The bandwidth would be 5KHz to 20KHz

Gold

So a 20kHZ or 30 MHz signal will require much different processing power to do an FFT on it.

Iron

What's BW?  "bandwidth"

Iron

@78RPM : and : do you need real-time ?

Iron

@78RPM : 1st question : what is your required BW ?  (Shannon's law and everything will start from there...) !

Iron

Thanks StephT. I'll check that out, too. I was thinking a PSoC that would do signal amplification via op amps in parallel, then >> A/D conversion >> digital filter and FFT for signal analysis in Frequency Domain. 32 bit is okay.

Gold

@78RPM : your FFT solution will depend on how fast, how deep you want the structure to be...  MAC (mult-and-accumulate) cells are what you need and even FPGAs have that (could be way faster than a DSP chip).

Would your CPU/micro need to be 32 b or less ?

I was at a Renesas trade show and they seemed to have nice chips / solutions.  But have not work with those...

An ex-MicroChip-Program-mgr was saying Renesas did it right (compared to the PIC32)... so he said...

 

Iron

Thanks jonf, will do

Gold

Thank you Charles for this valuable lecture, you have a great week end Sir.

Iron

Thanks to all, good subject, earned a few new neurons. T-Storms Time to play Ben Franklin and verify his findings?

Iron

@78RPM, re FFT's, you might check out any of the CortexM4 boards with the CMSIS DSP math library...

Iron

?? Hello Charles I am again, I know C and C plus plus but not C plus, C minus, C minus minus

Iron

Thanks for the talk!

Iron

Big T-storm headed my way - I'm going to drop off. Feel free to email me (address on every one of my slide sets, last slide) with further Q's or ideas for classes!  Thanks everybody for a great week!

Iron

78RPM, FFT comes down to a muliplication, seek multipliers in a microcontroller.

Iron

Great course. Thanks to all: Charles, Jennifer, Digi-key.

Iron

I like that!! We used to do these at local IEEE meetings

Iron

Also a class on patents and IP. it is too easy to infringe, if you think you came up with a better mouse trap. That's and idea in itself.

Iron

Thanks jamal. I'll check it out. Would be nice to have opamps and AD converters on the same chip.

Gold

@Charles: >>There is no known single cure.  And they will take individualized treatments<<

As Dr. Topol pointed out, there is not any `cure' for cancer.

Iron

Suggestions for classes. From what I have reviewed, things are hopping around a bit, since CEC inception. Structured flow would nice, evolving around a certain product or theme. As for specifics would have to dwell on that for a bit. There is so much out there and more coming everyday, it's hard to pin point the target from the "noise" When the light comes on, I'll relay the thoughts to someone here.

Iron

@Charles: Yes, please run the ethics class.

Iron

Thank you Charles.

Gold

@jonf, The emergence of Systems on a Chip (SoC) makes such preprocessing cheap and easy to develop.

Gold

78RPM A TI DSP is under 10$, for FFT you best go is DSP, 24 bits micronctrollers with math LIB an do it too. But if you only need some convolution than any microcontrollers can do

Iron

@78RPM - it did get lost - sorry. I will have to dig in my archives for what is currently available. In the past we off-loaded to TMS320's that were in turn programed in Matlab...

Iron

Thanks for bringing out the potential for preprocessing/data reduction at the sensor node.  Where you have both the power budget and the mips to support it, minimizing traffic over the transport is really desirable...

Iron

C minus and Cminus minus were languages designed as 'pseudo assembler' languages and are not in current usage, particularly for micros.  C and C+ are the current "C" variants

https://en.wikipedia.org/wiki/C--

Iron

?? Charles, can you suggest a chip or SoC that does FFTs -- and costs between 10 and 100 dollars? Availability of an Eval board would be nice, too.
(My question might have gotten buried in the crowd)

Gold

 I know the programming language C, C +

Iron

Sorry!

I know C and C+ but not C and C-, C--

Iron

I see there point but always believed, get them in the door, we will take lic at a different point depending on the cust comlplexity.

Would think that the silicon mfgrs would provide a good well rounded software platform w/o royalies to get more folks into there products, therefore more sales. Always setting the barriers to entry high eliminates a lot of smart folks. That is where Parallax Rasp pi and now a flood of others took in some good $ and got this all started, and now everyone whats a part of it

Iron

I like the idea of a class on GPS too

Iron

I know C and C+ , but not c and C-, C--

 

Iron

Cancer and the "common cold" are very individual afflictions. There is no known single cure.  And they will take individualized treatments

Iron

What do you see as your biggest challenge in the IIoT?
security implementation is going to be a big challenge for HiSec critical applications.

Iron

@Kurting - do you mean C, C+ , and C#?

Iron

I would love to do a class on ethics - I will work on a pitch for that

Iron

Re IPv6 and Freescale MQX - I think they felt that the support level needed was going to be the point that they needed to include support pricing.

Iron

@@ A webinar on the GPS and related systems would be great. A webinar on engineering ethics (thinking ahead ) would be great. I have seen and been involved in projects where the engineering was sucessful but the results ( colateral damage ) were pretty horible.

Iron

Future courses I'd like to see:

1) comparison among alternatives for energy-efficient low bandwidth wireless sensor networks

2) basics of Kalman filters for sensor fusion applications

Iron

Slide 16 "If all you hve is a hammer...", then slide 21 "The creative Destruction of Medicine"

Here is an article by Dr. Eric Topol himself on MedScape:

Topol on Cancer 'Cures': Are We Being Misled?

On page two, he cautions the claims of cancer 'cures'. This was June 14.

Contrast this with his talk point on slide 21 (bullet point 3.)

 

Iron

?? Hello Charles, sorry !! this is not currently our topic,
you certainly know what the technical terms "C+, C-, C- -" mean.  Can you pls explain for me with a few words?

Iron

You are back. Why does Freescale charge for IPV6 on the MQX? See that ipv4 was free ipv6 was the lic fee 

Iron

And thanks again for the kind words! I am putting together some more "design something" classes for future consideration here. I will be teaching classroom classes this fall but they are not announced

Iron

thanks again Charles and Jennifer

Iron

@FireFlyBlu - thanks!  I should have checked :)

Iron

Thank you for a good week of great lecture

Yes - FYI the IPv6 class will be the week of Sept 8 right here!!

Iron

Thanks Charles, Jennifer, Design News, DigiKey & IEEE !

Iron

Thanks Charles, an interesting week. See you in September.

Iron

For future course, I would like to see:

 - something covering FPGAs

 - a more advanced course on the Arduino

 - possibly a review of a common electrical design (could be just about anything - power supply, amplifier, wireless node, etc.)

 

Look through the archives. some fpga material was covered. These courses have been going on for about two yrs. I spotted it. Did not get to it (yet) Alot was covered.

http://www.designnews.com/archives.asp?section_id=1636   View content by month

Iron

Thank you Charles and Jennifer for this course.

Biggest challenge : most probably integrating everything !  It will be case-by-case (or application-by-application) but I'm still not convinced everything need to be Big Data, Cloud or broadcasted to all the atoms in the universe !  Many applications will need (still) to be wireless (cannot be "leashed" by, say, optical fiber), so IPv6-over-the-air ??  Probably better ways to do that, but Wi-Fi solutions do exist...

 

Iron

Charles' question was: What new topics would you like to see?

Something about GPS

Microcontroller system security, Atmel's fusion and Freescale's Xtrensic all would be interesting topics.

Iron

Driverless technology not unlike the automated shuttlecraft the Russians use. Over the road...

Excellent lecture, I really get this one.

Iron

Good Week, Charles & Jennifer - Thanks - JimT signing OUT!   Have  agreat w/e - !

If there is a class which requires some software and hardware then it should be clearly stated a few weeks ahead of time so that we can acquire them and get ready for the class. This would be most helpful. Like the course starting on July 7th Designing With ARM Cortex-M4 (& a Real Dev Board). Discount on those items will help too.

Iron

Charles' question was: What do you see as your biggest challenge in the IIoT?

With intelligence all of the obstacles that come up can be overcome.

For future course, I would like to see:

 - something covering FPGAs

 - a more advanced course on the Arduino

 - possibly a review of a common electrical design (could be just about anything - power supply, amplifier, wireless node, etc.)

Iron

@Charles @Jennifer Charles can lecture more classes like the recent MQX/Freescale ARM class. Make something practical from start to finish. Charles presents this stuff well. I know there is an upcoming class of similar material.

Iron

Along the lines @joshld was saying, just writing device drivers.  I am trying to write device drivers for USBTMC for PIC32 without much success.

Iron

?? Charles, can you suggest a chip or SoC that does FFTs -- and costs between 10 and 100 dollars? Availability of an Eval board would be nice, too.

Gold

1. security and how long it will tke to integrate IIOT.

2. IPV6 or GPS and satellite standarts.

Thanks a lot Jennifer, Charles, Digi Key's CEC, and ALL OF YOU, for a great week of lectures on IIOT.

Iron

IIot reference design for low power sensors.

Iron

Thanks Charles, lot of challenges ahead.

Very good class and lecture.

Looking forward for another one from you.

Iron

Need better discounts on development boards, cost for higher end bds is still way up there.

Iron

To me the question is how fast will the IOT unfold. Is it a few years or will this will be slow-rolled. I am an entrepreneur, so the pace does make a difference.

 

Iron

Thanks Charles , very nice series of lectures

Iron

Thanks Charles, Jennifer, Design News and Digi-Key

Iron

Thanks Charles, Jennifer, Digi-key, DN, Et.Al.

Iron

Excellent class thank you very much Charles and Jennifer

PS Yes a course on IPV6 standard would be very good

The biggest challenge in the IIoT are security and standardization(conformity).

Iron

Thank you Charles and Jennifer

Iron

New topics, CAN bus / OBD-3

Iron

Biggest challenges are twofold - integration of various protocols and standards for interoperability and maintaining robust security amongst all the devices (including the cloud)

Iron

Thank you Charles

Iron

Additional Class -- FreeRTOS for one of the Discovery Board classes -- as an add on to people who got the board or can buy one.

Iron

Thank you Charles and Jennifer for a week of lectures.

Iron

Charles' question was: What new topics would you like to see?

GPS.

 

Iron

Thanks Charles! Great week.

New topic? Would it be possible to hold some classes catered towards embedded linux, more specifically writing device drivers?

Iron

Thank you, everyone!

 

Thanks Charles great course!

Iron

I want to contribute to the IIoT and IoT, but being able to sort out the technology while it is fresh will be a challenge.

Iron

Coffee break - back in one minute!

Iron

Thank you Charles, Design News and Digi-Key

Gold

Thank you Charles. This was a very eye opening course. It gave me a different perspective of the internet.

 

I am totally not qualified to answer the questions you asked as I had difficulty with a simple engine electrical systyem and this is way--- beyond that.

Biggest "IIoT" challenge: I'm going to be boring and say (still) security and standardization, because I still do not see those very well-known issues being addressed universally.

Iron

Thank you for another great series!

Iron

Great survey on an important up and coming topic! Thanks Charles!

Iron

would like a class on Cypress PSoC and PSoC Creator

Gold

What do you see as your biggest challenge in the IIoT?


Multiple challenges: convincing clients to take the security issues seriously and trying to find the "best" solution for a particular device with so many protocols (Wi-Fi, BLE, etc.) and devices (SoCs, modules, etc.) to choose from.

Iron

Additional classes? Maybe on Lattice FPGA

Iron

Charles, Jennifer,

Thank you both

Iron

For me, it seems like the latest "buzz word".  Seems like there is some applicability in most industries. Also seems that many companies are talking about implementing it for their customers, but no one wants to be the first to do so.  Many are afraid to start down a road that ends up NOT being the standard approach.

Iron

Bits to kilobits to Megabits to Terabits and beyond w/ K.I.S.S...

The more the merrier, no challenge today, maybe tonight however.

Iron

Thanks Charles and Jennifer

Iron

Thanks Charles! Great week.

Iron

Thanks for a great week of lectures!

Iron

More classes on MCU would be good

Iron

I like the hands on MCU and RTOS classes

Standardization on the IETF stacks over 802.15.4g needs to proceed quicker. ZigBee NAN Worg Group and Wi-SUN need to accelerate their work.

Iron

Charles' question was: What do you see as your biggest challenge in the IIoT?

Security

 

Charles' question was: What new topics would you like to see?

 

I would like to see a class on how to use GPS.

Iron

What new topics would you like to see?

Fault tolerance

Iron

Thank you Charles and Jennifer.  Very informative

Iron

My biggest IIoT challenge - not knowing what all my challenges will be.

Iron

Biggest challenge, understanding ramifications of ipv6.
Thank you so much for this class!!  Looking forward to the Sept class.

 

Iron

my biggest challenge will be to keep up with new technology, techiques and anticipating how they will change (progress?)

Iron

Biggest IIOT Challnge? Nothing specific -- other than raising R&D money for new ideas and products -- always a challenge.

Iron

The biggest challenge in the IIoT? Probably facing the challenges of security that come with it.

Iron

Great session Charles!  One of the best I've been in on.

Iron

My biggest challenge of the IIoT is what exactly is it?  Nabto claimed that the Ethernet stack is not required for the IoT but I'm not seeing it.

Iron

What new topics would you like to see?


Multi-processing

Iron

Biggest challenge I have is keeping up with changes in the technology. 

Iron

My biggest challenge is likely to be getting IPv4 and IPv6 working together on the same network.

Iron

I see security as biggest challenge

Iron

Getting enough of it, without having to pay thousands in roality fees to every company

Iron

Charles' question was: What new topics would you like to see?

>>personalized medicine<<

I am not buying this. We still don't know much about root causes of cancer, for instance.

Iron

Work with some data analysis, but not big enough at the moment so as to have challenges posed by virtue of its size/volume.

Iron

Charles' question was: What do you see as your biggest challenge in the IIoT?

Thanks for the correct answer, I always thought the correct answer is 6.  

Iron

If humans don't have a way to deactivate a computer that has run away condition, than we got a problem

Iron

Not working from the "big data" side.

Iron

That's what they want you to think... ;)

Iron

Actually the way it works is that computers cannot comprehend without our help.

Iron

Things will get so complicated in the future that the human mind would not be able to comprehend without the help of computers

 

Yes this is a danger, who controls those computers.   Like Stepford wifes

Iron

@kchandra "Things will get so complicated in the future"... Yet that vey idea was suggested to be an asset when we want to distribute security across resouces in a network. No one node is responsible for all the security.

Iron

It would be interesinting to see the price of the pill specificly design for me knowing my DNA?

1M$ ???

Iron

Things will get so complicated in the future that the human mind would not be able to comprehend without the help of computers.

Iron

They all wanted to patent the Genes, Justice dept put an end to patents against natural genes.

Iron

Seems like sensor fusion functionality could be combined with gateway functionality => device both receives sensor data from multiple sensors (possibly from a low-power, short-range wireless network), processes the data appropriately, then passes it off to a higher-speed/bandwidth network...

Iron

My audio is 37 seconds behind Jennifer's.  Wow.  Big buffer.

Iron

harles' question was: Who is working from the "big data" side? What are your biggest challenges?

Not yet at Big Data.

Not currently dealing with legacy or mismatched protocols.

Iron

are not some of these silicon(s) integrating the sensors onboard? eliminates chip count. Last was ASIC are being emulated by SOCs

Iron

Seems like there needs to be nested standards for the various applications that vary based on data payload, security and determinism.  One size fits all doesn't seem practical.

Iron

Point of sale malware. They are issuing new cards by 2015, some this year, bye for the most part to the magnetic strip, smart chip and secondary authorization.

Iron

Sattelite internet is changing, new sats going up , and disp;laying 4k tv

Iron

Charles, have you seen the Freescale Tower Metro Kit ? www.freescale.com/twr-metro-kit

It is CoAP, UDP, IPv6, 6LoWPAN, TSCH, 802.15.4g subGHz mesh. Massively scalable to 4000+ nodes perr gateway 20 hops deep.

 

Iron

I think that the general IoT will be a concept.  There will be different (as you said) universes, with their own standards.  Most will have common fundemental rules, but different applications will require specific rules.

Iron

We deal with "Big Data" -- millions or hundreds of millions of points per run sometimes. Or thousands of projects with millions of points collected. We use Interbase SQL server -- since maintenance and setup is relatively simple.

Iron

Today in the TV News says that Inteligent Power Comsuption Counter (Tax Meter) have a blinking LED that can help thieft to know if a house in habitated or empty, simply, LED blink more slowly when there're a low comsuption: This is a great risk threat in the IoT. It's so ridiculous than the contdown timer displays of the bombs in the movies.

Iron

Charles' question was: Who is working from the "big data" side? What are your biggest challenges?

I n the past have faced similar problems.  Have had great success with data compression.  This however can be data dependent.  For example streaming video can only send pixels that change from one frame to the next.

Iron

?? Hello Charles, sorry !! this is not currently our topic,
you certainly know what the technical terms "C+, C-, C- -" mean.. Can you pls explain for me with a few words?

Iron

I develop TMDE.  What if the user wants the raw data?  That's 1M readings per second of 2x24bit ADC's and a 32 bit counter.

Iron

No legacy or big data issues yet as this is my introduction to this world.

Iron

A good application of Big Data would be Zooniverse style web sites that help scientists find planets around stars or count animals on the African Savanna or classify tiny fragments of ancient Greek parchment.

Gold

No big data, but certainly "medium" data.

Iron

not working with Big Data.

Iron

the big data issues I deal with is extracting knowledge from the data

Iron

Not working in that area.

Iron

Re: standards

Also search "IEC IOT"

Iron

Big Data will need to be "clasified", say: "industrial, science, medical, comercial, etc".

Iron

Not having to deal with big data.

Iron

Interesting - my audio is well behind Jennifer's audio.

Iron

Not looking at this from Big Data stand point.  But this will definitely affect us.  We need to understand how to use our Big Data.

Iron

Self correcting firmware software  Artifical Intelligence, self learning machines these correct some problems. Work in progress 

Iron

Unfortunately we're looking at it from both sides...  Providing as much data as we can, and then how do we get it and what to do with it once we have it.

Iron

Not at the Big Data level yet.

Iron

Not yet dealing with Big Data.

Iron

Charles' question was: Who is working from the "big data" side? What are your biggest challenges?

Interfacing issues hi to lo  lo to high 6 to 4  4 to 6 etc can all be solved, it's just how cheap can it be done and be done reliably

Iron

Iron

@Charles - don't drive in Milan.

Iron

No legacy issues for me

Soluton to big data seed is the technology R&D is developing now - Photonics an area that is not even defined yet, just a lot of neat discoverys that are yet to come.

Iron

No legacy issues.

Iron

Charles' question was: Are you facing the interface to legacy or 'mis-matched' protocols?

We're not facing the interface to legacy yet.

Is IEEE or any other industry group working on standards yet or is it still to early?

Iron

>>Passing hi-def EKG data<<

Might be a soilution: Have local device do more processing then transmit summary info

Iron

If you experience audio interruptions and are using IE, try using FF or Chrome as your browser. Many people experience issues with IE. Also, make sure your flash player is updated with the current version.

Iron

Packetize low speed comms onto high speed networks.

Iron

No legacy interface issues currently but had issues with little-endian/big-endian in the past. Also had to write a translator for PCCC (old Rockwell Automation protocol) to ControlNet many years ago.

Iron

Low speed?  Try using a 7MHz carrier.  Long range, atmospheric issues, very slow data rate.

Iron

audio  is clear and steady

Iron

I' sorry. I ment the other way around. from high speed to low speed, Not to higher speed.

Iron

Buffer the low speed and use polling to retrieve data off a node

Iron

Yes, there are difficulties and we need to check that compatibility routinely.

Iron

I2C / W-DMX data transmission speed issue.

Iron

Yes  we do have problem with legacy systems. We have embedded processor to bridge the various protocols.

We have a professional team of programmers that work on those problem everyday. Bridging theprotocol is essentially the back bone of our company

Tower of Babel network - Yes it's an issue.  Inserting intelligent nodes with lots of storage and data distilling to send along at pre-defined intervals in some systems.  On other systems we're just drinking from the firehose.

Iron

Luckily I don't have to interface with other people so I get to choose the standards to use

Iron

Charles' question was: Are you facing the interface to legacy or 'mis-matched' protocols?

 

Not currently but have faced similar problems in the past.  I can recall of at least one case where we had a big / little endian issue.  The one group had simulated it on ASIC and all was fine but the signal was backwords and thet next group consequently processed it wrong.

 

Iron

Greetings from South Florida

Best router is the Apple Airport Extreme

Iron

Haven't had any issues yet

Q1: Yes! data translation, units translation, and network speed matching/packaging/handshaking

Iron

Seen problems with mis-match protocol and speed.

Iron

Most of my legacy issues involve incorporating older SW libraries and drivers into a newer produst

Where my power budget permits it, I do substantial preprocessing/sensor fusion at the sensor node,,,

Iron

Ive only dealt with translation of lhigh level languages and protocols. Though all warking at the same speed o higher, not to "lower speed".

Iron

Can you provide guidanec as to who might be the manufacturers to look at for getting demonstration systems rapidly deployed with as little up-front time as possible? Looking to evaluate systems of a couple hundred nodes, so setup time is an issue.. Thanks

The streaming audio player will appear at the top of this web page when the show starts at 2 PM Eastern time today. If the audio doesn't start automatically, click on the play button to start it. Note however, that some companies block live audio streams. If when the show starts, the audio bar doesn't appear or you don't hear any audio, try refreshing your browser. If that doesn't work, try using Firefox or Google Chrome as your browser. Some users experience audio interruptions with IE. Also, make sure your flash player is updated with the current version. If that doesn't work, your company is likely blocking the live stream. The class will be archived immediately following our live taping and you will be able to listen to it then. You shouldn't experience any problems with the audio when listening on-demand.

Greetings from Raleigh, NC
