hey guys,
im kinda new at this, im trying to program a 16F877A PIC microcontroller to recognize specific audio frequencies at certain time intervals - for example, 300Hz at 0 sec, 545Hz at 2 sec, 1231Hz at 5 sec, 300Hz at 7 sec and the loop goes on.. of course the audio input is supposed to be through a microphone or two
now herez my problem, i've read a whole bunch of tutorials on programming PICs, but i havent found what i seek
i've also read the Microchip datasheet on their ADC module
but i havent found an example on how to program such thing
so im kinda really totally lost here and in need of help, if any1 may kindly suggest any solutions
thnX 4 ur time
