    web site / blog like 43oh for STM32?

    in Other Microcontrollers

    Posted

    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++;

    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

    MSP430 USI i2c and Adafruit LCD backpack

    in Code vault

    Posted

    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

    in Embedded Systems/Test Equipment Deals

    Posted

    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

    apparently you can now go down to a 2ns rise time

    post-105-135135538897_thumb.jpg

    not Rise(2) look at Time 2.000ns

     

    anyhow I'm not complaining this should be more than enough for me.

    TI Sample Program

    in General

    Posted

    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.
