  1. Thanks blue I had checked out the LMF4. A little pricier than the stm32 board. I like the oled on there and its got alot of cool features. I just cant do the 150. for an eval board , would rather buy a logic analyzer or other tool for my bench.
  2. Ive been playing with my f4 too. I really like this chip and board. I wish TI had a similar arm core development tool in this price range. here is some more info but its for windows. Im running: windows 7 64 bit on my main box and an xp setup on an old laptop I have this seems to work on both of them. You have to down load the appropriate version of eclipse. eclipse for editing codesourcery G++ lite toolchain atollic gdb server for debug. I used these links for info on the toolchain setup: http://shareee.netne.net/wordpress/?p=5 https://sites.google.com/site/stm32disc ... evelopment this guy and his site are awesome! I had some questions for him about his c++ toolchain and he was super cool, responded to a PM and gave some great tips, also I think he has some great code! http://andybrown.me.uk/ws/. Ive read on some of the forums and random places that the hardware fpu on the stm32f4 discovery board has to be enabled in the linker and in some of the startup code for the chip Here is a link to the eevblog where they are talking about it: http://www.eevblog.com/forum/microcontr ... bi-gcc/15/ and this says fpu can be enabled with c or c++; http://stackoverflow.com/questions/1058 ... -arguments and then this toolchain is sounding pretty good too I havent tried it and I think it supports the fpu https://launchpad.net/gcc-arm-embedded I havent tried this yet but am working on it now. hope this helps I just got this going today I have a better lcd on order just for fun
  3. Did you name the main with .cpp when you created your project? Thats how I compiled it with CCSV5. hope this helps
  4. Thanks SugarAddict! Got my lcds and they are killer! Also got the "smile it improves face time note" Oregon to Mass. and back Awesome! thanks again
  5. Ive had this Adafruit Lcd backpack for a while and thought I would get it working with the launchpad. I'm using a sparkfun level converter, and I am powering the LCD via the TP1 port on the launchpad. For the i2c code I used fj604's from here: viewtopic.php?f=10&t=1037 The code sends characters 2 different ways, one char at a time , and using oPossums tiny printf from here: viewtopic.php?f=10&t=1732 Maybe someone can use this. The code is attached, its a CCSv5 project. here is my setup here is the backpack. (I added the led for debugging) small video(really impressive!) LCDi2cdemo.zip
  6. Very cool! Thanks for doing all the work. Between you and RobG we can all just plug and play. Sweet!
  7. great job! cool blog too.
  8. I ordered a USB stick from avnet yesterday right after the presentation. They had 46 in stock at that time. I checked the order later in the day and they had 0 stock available. Im really looking forward to the ccsv5 deal. thanks for the tip blue! :clap:

  10. Ok I will fix when I get home! thanks this can be removed thanks
  11. So I got the Rigol. It is my first true DSO. Im really happy so far. I played with it a fair amount this weekend, and I went back and forth on weather to do "the hack". So this morning I said WTF! its only money and went for it. Here are the results. before notice model number after notice model number :clap: apparently you can now go down to a 2ns rise time not Rise(2) look at Time 2.000ns anyhow I'm not complaining this should be more than enough for me. if you want to do it check out http://www.eevblog.com/forum/blog-speci ... mmy-guide/
  12. this page http://www.geocities.com/dinceraydin/lcd/index.html Has a ton of info on the HD4478 lcd driver IC. He even has a LCD simulator. hope this helps
  13. thanks again for more awesome code!
  14. Ive been waiting for a good deal on this scope. I've been looking at ebay for a used one for awhile, and that just doesnt happen all that often. I just ordered it moments ago! Thanks for the tip.

    TI Sample Program

    I changed my email info to the email I have at work which is a .com address. Then I requested the samples again, they took the request then sent me another email saying that before they could send the samples to me there business manager had to give the ok. After that I received no more correspondence. About a week later the samples were at my house. :thumbup:
