  1. 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:

    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!



    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++;

    and then this toolchain is sounding pretty good too I havent tried it and I think it supports the fpu


    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

  2. 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!)


  3. 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.

  4. 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.
