PIC Tone generator


Posted on Oct 3, 2012

This program uses an 8 bit DAC along with a 16F84 PIC microcontroller to generate a keyed sine wave. The 16F84 uses an RC clock which can be varied (with a suitable potentiometer) to allow a variable frequency control for the sine wave output. A key or keyer output can be connected to pin 1 of the PIC to control the tone output.
