mikee Posted July 25, 2013 Report Share Posted July 25, 2013 Hello all you mad crazy midiboxers. I am about to build a circuit which needs two pic chips: one for a MB64 and one for a midi filter (by TK). Both chips are the same (old Pic16f877a - because I have some). Both circuits work fine with their own crystal osc, but I consider this a bit wasteful, and anyway, I have a 20mHz module I have been meaning to press into service for some years. I intend to drive both chip clock input pins "OSC1/CLKIN" from the single output of a TTL clock module (because I have one). The other clock pin "OSC1/CLKOUT" on each chip will be left open. I assume the relevant config bits will remain unchanged as 'HS'. I would appreciate any comments regarding the above. Thanks for looking. Best regards to all. edit: moot point, but I should have written MHz. Quote Link to comment Share on other sites More sharing options...
mikee Posted August 15, 2013 Author Report Share Posted August 15, 2013 I built the circuit, and used a module to drive three Pics, config is HS, not one problem found. Quote Link to comment Share on other sites More sharing options...
