Appendix 2: Sample Code

The sample code below is used to communicate to the FMT using a PIC
micro controller, when using this method in conjunction with
outputting information on a video screen a user is able to see visually
on screen the status of the FMT.

Example Code

I/O Name Function
SEL1_A: Clear
SEL2_B: Clock
FMTLOAD: Load (reset)
*** INITIALIZATION PROCESS ***
// Initialization I/O
SEL1_A = 1;
SEL2_A = 1;
FMTLOAD = 1;
// Reset Counters
SEL1_A = 0;
< delay 2 microseconds >
SEL1_A = 1;
// Restore Previous
< read stored station from EEPROM >
< call function to update the FMT device with stored station >
*** FMT DEVICE UPDATE PROCESS ***
// verify that new station is to be programmed
// reset counter
SEL1_A = 0;
< delay 2 microseconds >
SEL1_A = 1;
// increment counter until desired station is achieved
