Long time ago, I got a (free) TI ez430-F2013 development tool (a USB stick basically); it has a MSP430 CPU, a LED, and some pins.

Ubuntu comes with everything you need: binutils-msp430, gcc-msp430, gdb-msp430, mspdebug and a kernel driver for the USB/JTAG converter.

Use msp430-gcc -mmcu=msp430f2013 -std=gnu99 -g ledon.c -o ledon.elf to compile a simple program to turn on the LED. The resulting binary can be loaded using mspdebug -d /dev/ttyUSB0 uif and executing

erase
load ledon.elf
run

Debugging is straighforward: run, step.

#include <msp430f2013.h>

int main (void) {
  /* We want P1.0 output */
  P1DIR = 1;
  /* Turn on the LED */
  P1OUT = 1;
  return 0;
}
         

128 Byte RAM and 2 KB Flash Memory ought to be enough for everybody...
