Some features: - 11 LEDs charlieplexed on 2x 3 I/O pins (6 LEDs per 3 I/O lines, one LED not placed) - As low power as can get (900 nA in stand-by) - 14-pin value lin MSP430 - watch crystal sourced (32768Hz) - two buttons (of which one is on the reset line) - well under 2kB code (1.6kB) The "display refresh rate" is 512Hz, which makes the "pixel refresh rate" at 85Hz, a comfortable rate for the eye.
