• Scott Dattalo Tweaking a PIC for twist (use the PIC MPASM source to SX SASM Source Converter by Nikolai Golovchenko)
   
• Frequency Detection VP This example program measures power present at a specific frequency. The program is designed to run through a terminal connection to a PC, with the baud rate defined in the source code. The user is asked to enter a frequency from 0 to 13107Hz in decimal, and the program measures the amount of power present at that frequency.
