    veryalive got a reaction from yyrkoon in Flashing Firmware on a DIY MSP Launchpad   
    Hi Yavin,
    I am trying this approach myself - copying the application in Flash (I do not call it EEPROM) of the 2553 on the Launchpad into my PC, then into a target 2553 via Spy By Wire (SBW).
    I found a free tool at:   http://www.elprotronic.com/download.html   -  then scroll to the bottom of the page.
    It is called     FET-Pro430 Lite Software.   The user interface is pretty easy.
    I in fact used this tool to copy / save / reprogam the firmware initially delivered with the 430 LP.
     
    Hope this is of use to you.

    Hi guys,
     
    I'm new here. Just bought an msp430 Launchpad and a Capacitive Touch Boosterpack.
    Will be leeching the first few weeks (e.g. account enables download for touch library) but I might contribute some useful stuff later on.
     
    43oh looks great, nice meeting you all!

    I think at least 4 of the views on this thread are mine. ;-)
     
    I owned a TI-99/4A back in the early/mid 80's. I find it curious Tandy would pick up the publishing rights for a processor they never used.
    The TMS990 and 9900 had HUGE advantages over the 8086 and 8088, like separate data and address buss.. 16 bit as opposed to 8 bit....
     
    the 9918 vdp was a 'marvel' if you will, allowing the various video modes it did and sprites while permitting "background" video sources.
    One could theoretically play a video through the chip and overlay graphics on top....

    I've found myself doing some things with Energia, then going into their source trying to figure out how and why what I've done works.

    Energia does ship with the command line program called msp430-gdb which can be used to attach to mspdebug in gdb mode.  You can use that to debug your code. Granted, it isn't a GUI based tool but it works great.  This is one of the big advantages the Energia + Launchpad combo has over the Arduino.  Our hardware debugger is included in $4.30. On the Arduino, if you purchased an avrdragon debugger,  it would set you back about $50.

    For developing my code I am using the latest version of code composer studio.
    I tried energia, but its too simple and doesn't have the debugging tools that code composer has. I also use CCS, because energia (arduino stuff), is not allowed at my school.

    Not trying to distract anyone, but I have 20 pin 2452 chips, which came with my Launchpads, in addition to the 2553's.

    Forget about the hardware behind CS. It is up to the programmer to drive the SS low when it want's to address a certain slave and can do that with _any_ of the GPIO's and does not have to be P2.0 or P1.4 for that matter. This gives flexibility and allows you to address more than one slave on the bus. Ignore the the hardware behind it. P1.4 (STE) is not setup as SS so you are free to use that pin for anything else.
     
    Hope this explains it.

    C code has been written for everything that can be done in C - and it still is working.
     
    Should compile with GCC with few if any changes,
     
    The assembly code that remains will require some changes to work with GAS. Probably less than an hour of work.
     
    Hope to post the code tomorrow. Have a few things to clean up.

    Actually, I don't understand as  pins_energia.h shows
    #if defined(__MSP430_HAS_USI__) static const uint8_t SS = 8; /* P2.0 */ static const uint8_t SCK = 7; /* P1.5 */ static const uint8_t MOSI = 14; /* P1.6 */ static const uint8_t MISO = 15; /* P1.7 */  
    and
    #if defined(__MSP430_HAS_USCI__) static const uint8_t SS = 8; /* P2.0 */ static const uint8_t SCK = 7; /* P1.5 */ static const uint8_t MOSI = 15; /* P1.7 */ static const uint8_t MISO = 14; /* P1.6 */

    Yeah, you're right, on the 2553 the hardware STE (/CS) is on port 1.4.
    I wonder, why did you choose 2.0 in the first place? Did you use a source library that had this pin set as the default?

    Hi all,
     
    First sorry for my english, I'm french ...
     
    So, trying to play with SPI and a nRF24L01, I met a lot of issues, nothing worked. After several days I was desperate and looking at pin mapping in the datasheet of the MSP430G2553 I found a difference with the schema displayed on energia's wiki : USCI_B0 CS pin is not on pin 2.0, but on pin 1.4 !
     
    Unfortunately I chose this pin in order to command the CS of my nRF, and I don't know why exactly but SPI refused to work. I changed to another pin and ooowwwww miracle it works

    On 43oh, a copule of people have made a bus pirate and a logic analyzer. You should be able to port them to the Stellaris Launchpad easily.

    Hello to the forum !! I'm posting from The Netherlands.
     
    I'm really turned on by the Launchpads and have 430 + ARM (latter should be delivered by end October). I'm busy with CCS and Energia for 430. I heard of possible Energia for Stellaris, nice for quick stuff.
     
    My background is more hardware/firmware; work with larger machines x86. But my roots and passion are smaller machines (HC11, 12, 08, 805x, etcetera). I am also a radio amateur and build stuff.
     
    A teaser: anyone want to build some basic but practical low-cost experimenter tools around LP? Thinking of small logic analyzer, small o'scope (like spmu025a), L/C meter, signal generators, etcetera?
