Hi, I'm new to using the PIC uProc and am trying to setup a target circuit. I am working with a PIC16c74. I have a 4M Hz, 8M Hz, and 20M Hz crystal (CYL XTAL CA-301 Type). All should be compatible provided I'm not running at low power. My problem is I didn't receive any spec sheets on the crystals, and do not know the proper circuit configuration for them. Any information on how to use the crystals I have to provide the oscillator input to the PIC would be appreciated. Thanks, -Aaron Buchanan ***------------------------------------------------------------------*** * Aaron Buchanan axb9910@rit.edu * * Dept. of Computer Engineering Rochester Institute of Technology * ***------------------------------------------------------------------***
