Internal Osc question.
Hi everyone.
I am using an 'F819 for a little thing I am doing.
I am doing some serial stuff using DEBUG at 600baud.
This works perfectly when using XT osc with a crystal, but as soon as I go over to INTOSC and define osc 4, the sent stuff turns into junk. I am viewing these items on the PBP terminal view.
This begs the question, just how accurate is the internal oscillator on these (& other) PICs. It's just going to be a pain to have to use a crystal, since I have already done the PCB for the project, or at least pinched one from another project that doesn't use serial coms.
