Simple Commands is a demonstration program for the 16F873A containing a Simple Commands decoder and example routines to enter and print single and multi-byte data values in HEX, change command bits, and control program execution from a serial port. Using the Simple Commands demonstration program as a starting point for program development and selecting and customizing the routines you need for your application, adding serial port commands and data entry to your PIC program is easy!

Simple Time Interval Counter with RS-232 Output - This counter uses a 14-pin 16F688 PIC, a GPS receiver 1PPS as a reference, has variable averaging time set by serial port command, and provides a 10-digit BCD output to an RS-232 port. It is a low-cost four-IC solution for determining the time difference between a locally generated 1PPS and a GPS 1PPS and logging the difference to a computer for analysis. Demonstrates the addition of Simple Commands in page 0 memory to alter or print a single variable in a user program.
