I assume you mean an audio range oscillator. It would probably be much easier, and much more accurate to use the PC speaker output. It uses a hardware timer to generate oscillations. It will not be affected by jitter due to interrupt latency. Just something to think about. > Regardless ;-) > Nouman Mounajed michael brown -- http://www.piclist.com hint: To leave the PICList mailto:piclist-unsubscribe-request@mitvma.mit.edu
