N Nanya New Member May 29, 2007 #1 Hi guys, Please does any one know how to generate call progress tones (dial tone, busy tone, e.t.c.) using a PIC microcontroller or does anyone know a link I can go to for more information? Preferably using the 16F84. Thanks, Nanya

Papabravo Well-Known Member May 29, 2007 #2 Not specifically, but in general I can think of at least two ways to generate audio tones. Use a sin(x) lookup table and output the values to a DAC Use a VCO with a DAC Input to control frequency FYI - as Nigel and others will tell you the 16F84 is quite obsolete and overpriced. The more capable 16F628A is the prefered part for that socket now.
