Please, can anyone give me idea or link on how to do this project: generating range of frequency from Hz to KHz (in square and sine wave mode) programmable using PIC16F876A. Its a function generator. Thanks in anticipation for your help.

For sinewave generation:

MSLOSC from MSI

For square wave generation:

Linear Technology LTC6903 & LTC6904

All are small serially programmable chips.
