 | C code development on the MSP430 microcontroller |
| 10-year lithium-powered real-time clock implemented using the MSP430
and taking advantage of its low-power features and dual-crystal capability (one
high-speed crystal for normal operation and one 32KHz watch crystal for time
keeping). |
| MSK Modem. MSK stands for "Minimum Shift Keying". It is a form
of audio modulation optimized for data transmission over analog radios. |
| DTMF detection and transmission. "Dual Tone Multi-Frequency"
signaling is what you hear every time you dial a touch-tone phone. |
| Infrared communications using IrDA-type transmitters and receivers |
| Serial flash memory |
| Security and encryption through the use of Dallas Semiconductor's
SHA-1(Secure Hash Standard) devices |
| LCD/keypad/beeper user interface |
| RS-232 communications |
