Just curious...not having any experience in DSpics. Looking at detecting a 38KHz signal, bascially doing the function of a PLL (this is a sine wave coming in) and also doing FSK decoding. Essentially this is a 38KHz subcarrer that has FSK (38K/42K) and presently doing it with a 16F PIC and an external PLL chip (567 I think..?). Can the DSpic do the PLL function..obviously it can do the FSK decode. -- http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist
