Thank you very much Fred

Iron

Yes used Pic's all the time

 

Iron

nope, not a PIC user

Iron

Great to have access to the recorded sessions!

Iron

Missed the live session

Iron

Taking the class offline

Iron

Thank you Fred, very informative session

Any suggestions on debugging technique

Both, FTDI 232 and MCU 

Hi from Portland Oregon

This looks very promising I cant wait till I join the smart phone revolution and get my galaxy s4

@ Fred Teacher

You did a great job as usual ,I guess everybody has already left .If i got a question regarding today's topic .will ask you tomorrow .Have a Great Evening teacher .

Iron

Fred - I asked the group early on today what devices will be targets for development, what devices do they use, what devices do they recommend. Do you have any input on this subject matter?
Thanks. Really enjoying your presentations.

Iron

Just wanted to make sure all of the questions got answered..

@ Teacher Fred

I am staying to review the Archive

Iron

Thank you. See you tomorrow.

Iron

Anybody still out there???

Blogger

@ebrown

Thank you!

Blogger
Fred - thanks for an excellent class

Ok Thanks teacher see you tomorrow

Iron

@farhad21

No worries :-)

"See" you tomorrow..

 

Blogger

@farhad, from Design News Home page, click on Next Class Day 4.  That will take you to the list of classes in this course.  Go down to Day 3 and click View Archived.

To teacher Fred

Am so sorry I was late today

Iron

Thanks for all Fred and goodnight

Iron

@LTDan

Ok Thanks Dan

Iron

thanks to all and goodnight to everyone...see you all tomorrow for another great presentation.

@farhad - BTW, I'm using in Google Chrome...

Iron

@farhad - go to Full Calendar Curriculum, locate course of interest, click on View Archived. Audio player should display just beneath the class title. Just press the play button.

Iron

any type I do is just missed

Iron

How to access the Audio file archive !!!anybody knows!!!

Iron

@cghaba

Correct. If you are sending small control packets, there will be no problem.  If you are streaming large amounts of data, you will have to throttle the WiFi transmissions. The RN-XV's UART can work at 460800 baud. This is also discussed in the WiFly User Manual.

Blogger

To be sure I understand well, this means it is in my application in the laptop that I have to limit the wifi packet size according to the spead of the uart transmission? 

Iron

ok, i understand sir fred, thanks alot.

@ronaldgomeseria

Did I answer your question with the reply to cghaba?

Blogger

@ebrown

Sorry, the powerpoints are preloaded and cannot be altered.

I will put together a download package with that info.

Blogger

@cghaba

Yes.  You can send as many as 1500+ characters in one WiFi frame. The output speed factor is determined by the baud rate you set the RN-XV's UART to. So, you may have a device that can only run at 9600bps, which means you have to throttle your WiFi packets.  On the other hand, you can run at a higher baud rate, which will empty the WiFi buffer faster.

Blogger
Fred - can you provide a list of all the hardware used in these classes on the PowerPoint for the last class.

just keep reading all the blogs & feedback here...

Just got FT311D doc, thanks.

Iron

If I send 1000 bytes from the laptop via WiFi to the RN modules. Are they buffered inside the RN modules before they are sent via the UART port in order to accomodate lower speed?

Iron

yap, I am referring to cghaba's question...

Thanks Fred. Gotta get back to work now. Chat with you tomorrow.

Iron

Nighty Night, Ross ;-)

Blogger

Heading back to bed now (4:45am). Thanks Fred.

Ross

FT311D Development Board is matched with Arduino size?

 

Iron

@CCarpenter

Lt.Dan is on the beam :-)

Blogger

@ronaldgomeseria

How???

Are you referencing cghaba's question?

Blogger

Guides and tutorials at basic4ppc.com

Iron

You mean the buffer of the serial transmission?

Iron

@SChancey

Let's see:

New Micros for the XBEE Dongle

DigiKey for the FT311D Development Board

DigiKey/Microchip for the RN-XV

Hope that helps

Blogger

@CCarpenter - http://www.basic4ppc.com/android/files/guide.zip

Beginners guide.

Iron

@cghaba

The RN-XV does that automatically for you.  You can tune it a bit by altering the minimum transmit buffe flush size.

Blogger

Is there any particular document you would start with to gain insight into B4A and programming for Android in general Fred?

Iron

Please post retail sources and p/ns for the development boards.  No reason for everyone to find them on their own.

Iron

Thank you Fred. I'm luck that the sessions fall into my "lunch time". It's a valuable and interesting way to use my time.

Iron

Fred, how do you suggest to synchronize the Wifi transmission (faster) with the UART one (slower)? I send data through Wifi from a laptop to the wifi module and send it further to the microcontroller through the UART port. Data size is some thousands bytes. 

Iron

It was good to "see" all of you again today.

Thank you very much for taking your valuable time to attend this session.

Blogger

by the way, Leonardo also looks like a com port too!

Iron

I appreciate the user posts. I copy/paste them into a document in the same folder with the ppt slides.

Platinum

Sir Fred and Madam Jennifer

it will be a pleasure to See you and Hear you tomorrow.

 

Iron

You'll get there, Sercelusa - just keep attending classes!  =)

have used FTDI 232 chips for legacy interfacing through com ports. just getting started with USB enabled uC in the Arduino Leonardo. The Leonardo looks just like a PC keyboard and mouse to the PC.

@Don H

Thanks Don. I must have missed Fred mentioning that.

Thank you - very good

Iron

Tomasz - the class will be archived, so you can listen any time you want to!

Another good session.
Thanks Fred.
Thanks Jennifer.

Iron

Thanks Fred, and thanks to Digi-Key & Jennifer

Iron

I missed some of the live transmissions - can I listen again off line?

Tomasz

Iron

thanks sir fred and madam jennifer...see you tomorrow for the next class. actually, i am new with the subject that's it made me complicated...

I have used RN-XV because can be controlled via UART port. It has limiation on transfer speed (microcontroller- Wifi module)

Iron

Thanks. will try the procedure.

Iron

I haven't chance using RN-XV. Thanks Fred and Jennifer, I leant more thing from this presentation. Thanks again.

Iron

Fred, thank you for today's lecture

 

Iron

Thank you,

Jennifer,

Thank you,

Fred

Iron

Thanks Fred for presentation.

Iron

I'm new to the WiFi modules, but this is fascinating, and I'll certainly have to give it a go.

Iron

good lecture, later. Rod. R.

Iron

Thanks Fred, Jennifer, and Digi-Key!!

Iron

FTDI USB has been easier in my case

Iron

Thanks Fred and Jennifer.

Iron

We have used the FDTI USB but now use MCU internal to save board space.

Iron

never used rn-xv.  prefer to use ft232.

Iron

Have not used it yet...but soon.......

Iron

Have not used RN-VX, nor USB to this point

Iron

have not used any WiFi modules yet.

Iron

Thank you Fred and Jennifer

Iron

Nope - never used RN-XV.

Iron

Fred is wrapping it up. Join him on the live classroom chat page in about a minute or so, where he wil answer your questions directly.

I want to be gold

like Jeniffer

Iron

Rrrrr... there's got to be a better solution for this audio issue..  Maybe y'all could look at using something other than Flash.

Iron

me too, but interesting topic to learn...

Have not used the  RN-XV

Iron

Slide 15 - where the rubber meets the road!

absolutely in today's projects...

@Ross_Valusoft

RN-XV WiFly Module - Wire Antenna

https://www.sparkfun.com/products/10822

Iron

Most projects I've worked on recently have on-board USB.

Iron

never used RN-VX, yet.

Iron

on chip usb preferred

Iron

No audio today, could listen last 2 lessons, but not the archived ones. Bye, and thanks for everything!

Iron

Naitmaster - the class will be archived. You can catch up there!

Just for tests (R&D) not in projects.

Iron

All my USB designs have used FTDI chips so far. I may go with on-board USB in the future.

Iron

See you next Time. No Luck today!

Iron

Have not used the  RN-XV yet.

Iron

Have not used the RN-XV

Iron

No audio today...was fine last 2 days...Guess I'll have to wait for the archived version. I am able to listen to both prior archived versions so it should be fine. Thanks in advance Fred et. al.

 

Iron

I prefer onchip USB, but FTDI chips also. 

Iron

Have not used RN-XV module.

Iron

Have not used RN-XV

Iron

I prefer to use FTDI USB IC's to simplify the software requirements.

Iron

still working with a lot of legacy systems. RS232 is the preferred interface. USB enabled uC for future projects.

Iron

No sound here, and i'm in slide 0 (Zero)!!!

Iron

Have you used the RN-XV in any of your projects?

No preference on USB controller -- does it work? First and only quesation I ask.

Iron

I can't hear anything.

 

Iron

Slide 5 – Do you prefer to use microcontrollers with on-chip USB or FTDI USB ICs?

Do already start?

 

 

Iron

PIC24's, dsPIC and some PIC32

 

Iron

Howdy from Austin, Texas

Iron

Don't use MicroCHip except for Ethernet Interfaces

Iron

Used to use PIC. But not like it since only for Microchip.

Iron

greets!  from Bremen/Germany

Iron

Been a big PIC fan since mid 1990's. 

Iron

yes - use PICs regularly

Iron

I am a big fan of Microchip.  The development tools are good, but, more importantly, they deliver on time to meet production requirements.

Iron

No audio today. Had it past 2 days.

Microchip Pics in some systems, MSP and Renesas in others

Iron

Hve used PICs though not recently.

Iron

used PICs in projects since the PICStik products from micromint

Iron

All of our designs here are PIC based

Iron

Yes we use mostly PIC18

Iron

I have used PICs in the past.

 

Iron

Good Afternoon from Boston

Iron

Do you use Microchip PIC microcontrollers?

Good AM fromn San Diego.

Hello from sunny Atlanta.

Iron

emohammed - it's an audio conference with a powerpoint presentation you can download and follow along with. You can download the slide deck in the upper right corner under Special Educational Materials.

Is there a webinar link to todays session

 

Iron

Hi everyone, eight minutes until class starts. Are you ready? Please make sure to download the slide deck.

i already downloaded the material for this presentation and another excitement for the 3rd day of class lesson...thanks alot.

good evening to everyone and to our dear sir fred and madam jennifer...

@78RPM

I think that would be a good one to do if there is enough interest.

Blogger

@danlafleur - along the lines of what I want to accomplish for some of the embedded development I do.

Iron

field upgradable f/w through BT is an attractive feature to offer.

Iron

@WillP

Nope.. It's a hardware head's paradise today :-)

Hello from Tennessee

Iron

Just building my problem solving box of stuff for now. There are no immediate projects that target Android. My interest is in having a remote console through a smartphone or tablet into an embedded system. That allows configuration, control and f/w upgrading.

Iron

I'm curious - what target devices are you all developing for?
What devices do you own?
What devices do you recommend?

Iron

looks like a few "early birds" logged in. Remember that the early worm gets eaten by a bird.

Iron

hello all from soggy Edmonton, Alberta

Iron

@Fred - will there be any source code to download for today's session?

Iron

@78RPM - thank you for the tip.  I had been looking for a reason to buy BeagleBone.  Seems like the perfect solution with the GPIO ports for sensors.

Iron

Thanks for the confirmation DaveWR. I think most of us have extra displays laying around. You would have to add a 5VDC supply, an HDMI cable, a USB cable/hub. But this stuff is not expensive.  Digi-Key and Adafruit have some cool accessories for the BeagleBone Black.

Fred, would a bootloader for the BeagleBone be appropriate?  Care to teach a class?

Platinum

Good morning from Beaverton, Oregon. Overcast and 64º.

Iron

Greetings from Raleigh, NC

Iron

@78RPM

It's a thought -- but to do what Fred is showing here you need to add a display to make programming easy.

As I pointed out yesterday places like TigerDirect(.ca .com) are selling Android 4 devices for about $100.

I don't think you need a Galazy tab.

Iron

@R.F.Ehler

msp mn??

Blogger

Good afternoon mharkins! Yeah, Play button changes from > to

Iron

For those of us who don't have an Android device, I see that the BeagleBone Black computer is just out at $45 plus accessories. It's Android 4 ready. This looks like a less expensive and more versatile alternative to a Samsung Galaxy.  Any thoughts?

Is the audio player running when you click the play button?  Sound turned up (I know too obvious, but gotta ask :) ?

Iron

Good morning from Mobile, AL

Dear Fred & Jennifer, I'm trying to play the audio from Day 1 or 2 but didnt succeed. The audio player loads after I log in but there is no sound. What am I doing that is wrong?

Thanks!
