FYI  to Archive Users.  Instructor's Audio gets choppy at t=15 minutes and is completely lost at t = 17:30.

Iron

Catching up with archives.  Sorry sound went out but slides are great.

Iron

Thank you, till tomorrow 

15 minutes out of window

Archived sound is breaking

Late again, can't win with meetings going way over.

Iron

@cjlord - What about MQX Lite version? According to this page:

https://community.freescale.com/community/the-embedded-beat/blog/2013/05/13/the-bare-metal-enthusiast-to-rtos-or-not-to-rtos-that-is-the-question :

"... For example, a Freescale MQX Lite RTOS application with three tasks (plus one idle task), one semaphare and one event needs less than 8 Kbyte flash and less than 4 KByte of RAM."

However, I believe MQX Lite comes with CodeWarrior 10.3, but not 10.4. (need to confirm)

Iron

Just login, BLDC Motor Control, Touch sensor, Fuzzy Logic

Iron

Thanks, LtDan - that is the page I wanted people going to.  The Kinetis limitation keeps you from compiling implimentations of full MQX but otherwise the special ed is pretty good for teaching and small projects (like ours).

Iron

@cjlord, et aL. - If anyone is interested, Freescale offers evaluation versions of CodeWarrior 10.4 on this page: http://www.freescale.com/webapp/sps/site/overview.jsp?code=CW_EVALS

There are different versions for download, depending on your internet access capabilities (i.e.: download an installer, then download additional components; download an entire image for offline install, etc).

The software installs as the Professional Edition with a 30-day evaluation period. After 30 days, the license converts to a Special Edition license (free permanent, feature limited) (unlimited assembly code; up to 64KB of C code for ColdFire+, V1 ColdFire, DSC, Kinetis L Series, RS08, S08 derivatives; up to 128KB of C code for Kinetis K Series and V2-V4 ColdFire derivatives; up to 512KB for Qorivva and PX derivatives). This should be more than adequate for this experiment.

Iron

Houston, we have a problem

 

Iron

MEMS device lectures please

Iron

Hello everyone - Due to technical difficulties, we will need to finish this session tomorrow. We will add the rest of today's content into tomorrow. Same time same place. Again, we sincerely apologize for this inconvenience.

Untill tomorrow, thanks Charles

Iron

Thank you, we will catch up later on the audio on the archive. Have a great day

Iron

I wonder if the archival will work tonight / tomorrow?

Iron

thanks, until tomorrow.

Iron

Gotta get back to work now. I'm sure tomorrow's gonna be a better day! Thanks Charles, Chuck, Digi-Key and Design News.

Iron

Are we going to cover the rest of today and tomorrow's materials tomorrow?

Iron

Thanks. Hope better for tomorrow.

Iron

is it over?  I click on the audio link and get the archive of today...

Iron

I would also be interested in more RTOS, and Beaglebone & Raspberry Pi would also be interesting.

Iron

I'd agree with markr.  Would like to see more depth.

Iron

thanks for the effort Charles

Iron

Thanks all, see you tomorrow...

Iron

@cjlord - I'd go for RTOS with MQX...

Iron

Generally more depth on any topic. Most of the classes have been more introductory.

Iron

Thanks charles. Hopefully we have a nice class tomorrow.

Iron

RTOS is good - just getting it past management is the problem ("but this is the way we've always done it")

Iron

Yeah, richwilliams, Beagle Bone and Raspberry Pi sound fun. Not sure if those are okay for engineering applications. Any opinion?

Gold

See you all tomorrow.

Iron

Session on the Raspberry Pi

Iron

How about Far IR sensor technology and optics

Again, our apologies to all the listeners. Hope to see you back here tomorrow.

Blogger

I can hear that we will continue tomorroe, It's true?

 

Iron

Beagle Bone would be great!

 

Iron

Ditto on motion control and more in depth RTOS.

Iron

I heard a vote for RTOS such as MQX... how many would like a class in that?

Iron

Thank you veru much Charles

Iron

beat on the IT guys!!! ;-)

Iron

neural net feedback loops to fix motion problems!!!!

Other intersesting class possibilities

Class on Beagle Bone

Class on Raspberry Pi

Hello everyone - Due to technical difficulties, we will need to finish this session tomorrow. We will add the rest of today's content into tomorrow. Same time same place. We apologize for this inconvenience.

OK, it's time to earn my keep. See all tomorrow.

Iron

@Charles Murray - How about we reschedule today's session to let you guys work out the audio problems?

Iron

catch you friday, need a coffee

Iron

Yup motion control is good fun - until the mechanical dept. has so much slop in the system that you have to use stupid software tricks to make it work

Iron

maybe the post object has gone haywire????

Can't hear anything.

Logging out.

Iron

@markr, Actually, the only thing you really need to play with it is the Android device. One of the participants suggested the Kyocera Event for $68 and it works fine.

Gold

What is that she says?  "Lost Hope Radio?"

Iron

Motion control with MSP430

Iron

i think my keyborad is stuck!!!!

lost you will try later

thanks

Iron

Reloaded page, started sound and now its gone again.  3D Printing class would be nice our company is looking to buy one of stratasys line of 3D printers for rapid prototyping.

Iron

Anybody up for a double session tomorrow?

Gold

OH! Motion control is great fun!

The Android class required a fair investment in hardware.

Iron

going to have to catch the replay on this one, audio problems not resolving here.

Well, there's always tomorrow!  :)

Iron

Audio player not reloading on the refresh

Iron

Charles I don't see you in host queue.

 

 

Blogger

How about a roll-your-own JTAG class?

Iron

Ooh, I like 3-D printing!

@aak, They had Fred Eady do a class on Android a few weeks ago. Check the archive.

Gold

I would like an example implementing an RToS application, using one of the "free" ones from manufacturers, like Freescale's MQX. Folks can try without investing $$$. Also using that to implement a web server as an HMI.

Iron

Something on code coverage testing would be interesting also.

Iron

Some courses on analog design would also be good.

Iron

Audio artifacts to zip!!!

Iron

Accelerometers, 3-axis position hardware, gyros.

Audio player not reloading on a web page refresh.

Series on 3d printing.

Iron

When I call in, I hear the moderator choppy also

 

Iron

I agree, CAN would be interesting too

Iron

Chuck Murray your loud and clear,can you sing tomorrow

Iron

auto code generation - becoming more and more necessary with reduction in development times

 

Iron

Charles audio is getting worse, your voice is not clear.

Iron

SMPS: Flyback, LLC, QR, Push-Pull, Transformer Design, synchronous rectification, ...

Iron

I agree. Design News host audio is breaking up now.

Iron

Audio is very chopppy

Iron

@Charles Murray - now you're breaking up...

Iron

Hey Charles, now you're also breaking up on my end.

Iron

LED lighting and power controllers

Iron

oh audio is really bad..breaking up

Your audio is choppy now!

Iron

haven't used DEMOJM board

More indepth on going from state machine to RTOS design.

Iron

I would like to see something on 3D printing..

Iron

A couple of classes on programming interfaces with networking type connections; USB, Ethernet, Wireless etc.

Iron

Class suggestions:

An overview and comparison of the popular RTOSes

Debugging RTOSes

 

How to use various IDEs. There are so many IDE's and they are all different and starting from a blank project with many of them is daunghting.

Iron

Also Android Application development

Iron

Yes, agree with 78RPM: class on CAN would be good.

Iron

Not just his mic. Yopu are now breaking up as well.

Iron

I'm mostly a hardware guy, something not covered often is fault detection/fault tolerance. Could be applied to sw as well?

Iron

oh oh - moderator breaking up now

 

Iron

How about some of the VBA for Microsoft office products.  Just finished up on a special application running in excel.  More insight might be useful.

Iron

Audio getting choppy now.

 

Iron

ARM programming would be interesting

Iron

Also sounds like overmodulation

Now your audio is breaking up. I think you have network problems.

Gold

@FrodoH, they had a class on energy harvesting a few months ago. Check it on archive

Gold

I would like to see more on RF an DSP topics

Iron

With project related code examples

Iron

Possibly a class on micros and many types of sensors.

Iron

embedded tcp/ip with msp430

Iron

32 Bit arm boards/systems

@jjrochow: Me too....

Iron

How about a class on CAN?

Gold

Future technologies - where technology is going.

Iron

I am back in the host queue! hello???

Iron

More in depth RTOS discussions

Iron

More of the same maybe with MCU ARM programming

Iron

I would like to see more on closed loop motion systems

Will the playback also have these dropouts

Iron

too many InternetOfThings clogging up the interwebs

Iron

@jjrochow: I liked the HAL 9000 reference...

Iron

how about some elevator music?

Since there are a number of countries representated, we will have to pick a song everyone knows for the singalong.

Iron

All computer geeks have to learn "dasiy"...just like the HAL 9000

@jjrochow@ra.rockwell.com: Enter shameless plug here...

Iron

Hamsterdance video soundtrack???

Iron

oh well..technology is not perfect..some is better than others though..for example a Rockwell Automation controller is close to automation perfection!

And I could have had a V8!

Iron

We can hear you Charles, you can talk

Iron

Charles can you sing for us as we wait

Iron

oh oh - unhappy listeners - Starbucks for everybody???  ;-)

 

Iron

An intermittent mic or wiring may have been causing drop out audio in previous classes. Same equipment?

i hear the announcer only

 

Iron

anyone for a musical interlude?

Iron

I can hear the moderator

Gold

audio is back on after refresh of browser and play button

Iron

We are experiencing technical difficulties and are trying to resolve them.

Blogger

@cjlord: We know you love a good challenge! But seriously, Thanks for working to get the slides posted before the lecture. How's the rain down there today? Not surprisingly, it's raining in Portland today... 

Iron

Another challenging day here... Slides will be up in a while.

 

Iron

Morning from Portland Oregon

Iron

Good morning from Mobile, AL

Charles, I think for those of us who are just learning C, having a complete ccopy of the code available on your web site would be really useful

Making the slides available before the class takes place is very helpful. It allows me to preview the subject matter for the days lecture. Thanks.

Iron

RTOS when you can fit it in.
