Useing an 8 pin PIC, crystal oscillator to generate variable width pulses

http://www.microchip.com from "Simple Circuit" DD00097 useing an 8 pin PIC. Use the crystal oscillator as an RF source. Generate off "CW" pulses by sleeping on the WDT with the prescaler changed to generate variable width pulses. The tank can match the crystal or be an odd multiple:[画像:[Image]]
