I am new to PIC programming in C and have decided to learn by doing three various task, at the moment these worksheets I am totally stuck on where to start.

It goes as follows:

Task 1 : Transmitting Serial Data using the PICRadio

Write a PIC C program that will continuously output a UserID followed by a ID number on the RadioPIC PCB in serial ASCII form at 19,200 Baud, 8 bit data, 1 stop bit and no parity check, to the ER400TRS radio transceiver. Use the ER400TRS to RS232C PCB connected to a PC running Hyper Terminal to confirm the correct output.

Task 2 : ER400TRS Low Power Short Range Digital Radio Transceiver

Two ER400TRS digital radio transceivers are to be used to establish a bi-directional serial communication link operating at 19,200 Baud. Write a PIC C programme that will echo back every ASCII character received by the ER400TRS on the PICRadio PCB. Use hyperterminal and the ER400TRS to RS232C PCB to test out the system.

Task 3 : Serial Sequence Recogniser

An ER400TRS will be used to produce a continuous stream of serial data consisting of student userids. The byte following each userid is an integer value (0 to 9) that is to be displayed on the four LEDs on the PICRadio PCB. Write a PIC C program that will recognise only your specific userid and display the immediately following integer value on the LEDs. Undertake suitable tests to verify correct operation.

Any pointers would be great.
