Hi,   I came across a project that requires a 16F84/P-10 and a 10 Mhz crystal. I do not have any 16F84/P-10 but, I do have 16F84/P-20. Can I substitute 16F84/P-10 with the -20 part and still use the 10Mhz crystal ?   Thanks in advance for the help.

I have some books on the way to learn PIC programming. I think that the demos in the books are all based on the 16F84. This part seems to be a bit long in the tooth and also expensive compared to more powerful chips. Would the 16F628A be a good substitute for working through the books??? or would some other chip be a better choice. When I run a small program on the simulator the output for...

Colleagues, I'm trying to use the 16F818 for the first time (prior to this I've used the 16F84 and the 12F509). I want to use the internal oscillator, and I'm having a heck of a time getting the chip to operate reliably. I've got it set up so that OSCCON sets the clock to 4MHz, and CLK_OUT goes to RA6, so I can see what is going on with my oscilloscope. The problem is that the ch...
