900 MHz Wireless Control for a Stepping-Motor-Driven Rover

A TI TRF6903 Demo
Board will be able to transmit signals for pressing each of its 4 buttons (Red,
Orange, Green, Yellow) such that on a receiver board with the same ID code (see
8 below) LEDs of the same colors will light, and logic signals will be available
from a connection strip. See below for image of 6903 demo board.
A 20 x 2 female "breadboard" strip will be soldered to pins 3 above, on the receiver board. Power for the receiver board will come from a local 3.3v regulator on the rover, through power connection pins below ON-OFF 1, above.
The code for the MSP430F449 chip on the board will be written in C, with comments for documentation. The duration of the receiver signal can be varied in the C code, from 100msec to 1000 msec.
BONUS:
1. Other code will be written for the receiver to read 8-bits in parallel from
a LabVIEW connector card and transmit the bits down to the receiver. The bits
will be stored in a register for use in rover navigation algorithms.
2. For either the MSP430F449 or the MSP430F1232 Timer A will be configured to
to oscillate at 1000-10,000 Hz, available on pins of the respective Demo Boards.
