    Joby Taffey got a reaction from petertux in MSP430G2221 jar-of-fireflies   
    MSP430G2221 jar-of-fireflies
     
    A classic project, re-told on the MSP430 Launchpad's MSP430G2221.
     
    Glass jars of LED fireflies which synchronize over time. A piezo transducer in the lid detects tapping and randomizes the pattern.
    MSP430G2221, 7 LEDs, 2 resistors and a piezo transducer. Cheap and simple.

    (I've just finished this project and published the details, but it was already mentioned on 43oh back when I started it http://www.43oh.com/2010/10/msp430_firefly_throwies/ So, perhaps it's ineligible for the competition - no problem).

    Joby Taffey got a reaction from bluehash in Minimal CC111x OS   
    The Chronos watch is based on a CC430 - an MSP430/radio microcontroller.
     
    The pack also contains a CC1111 based USB dongle - an 8051/radio/usb microcontroller.
    I've written a minimal operating system for the CC111x, which should be capable of running on this device (without USB support).
     
    It's available here: http://code.google.com/p/pinkos/
    (note - to get at the serial console, you'll have to do some fiddly soldering)
     
    It should be possible to use the GirlTech IM-Me handset and dongle units to communicate with the Chronos watch, the IM-Me units both contain the CC1110 chip.
     
    If you don't know what an IM-Me is - this will explain everything.

    Joby Taffey got a reaction from jsolarski in GoodFET   
    Hi,
     
    I've reflashed the IM-Me using GoodFET. It's pretty easy. I'm using Linux, but it may also be possible from Windows.
     
    I have a GoodFET31. It wasn't too hard to assemble, but if you haven't tried surface mount soldering before then you might want to read up on it first (use plenty of flux and get a fine tipped iron). Travis Goodspeed will send you a PCB for $5 (or nothing if you're a student).
     
    The IM-Me chip is a CC1110, which is an 8051 based microcontroller. SDCC does support this, but MSPGCC is for MSP430 only.
     
    The GoodFET supports MSP430 JTAG, but I haven't tried it out yet.
     
    For goodfet questions #goodfet on irc.freenode.org is a good place. It's pretty quiet, but if you leave your message in the channel someone will usually respond eventually.

    Bill,
     
    I've built a couple of projects which parse serial input (based on NJC's code). They should be easy to adapt:

    It's the RFID reader is SPI, then my SPI Explorer should get you most of the way there.
