I have hex values of a sound in my EEPROM and I wanna use the PWM of my PIC16f877 to play this sound. So basicly how would I go about it!!!!

how do I write to the PR2 register and how can change my frequency to modulate the signal in fonction of the hex values of the sound

Open the file 93C56.C (included with CCS compiler),
to see how to communicate with a eeprom

open ex_tones.c(included with CCS compiler),
to see how to use the PWM for making noises

Marriage these 2 techniques together to get what you want

----------------------------------------------------------------

Try using 2 PWM to produce tones of mixed frequenices

eg 1kHz mixed with 10Hz etc....

Hope this helps!
