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, In recent threads a number of you have sounded words of caution about using C for the "smaller" PICs, such as the 12- and 16-families. What would you recommend as a sensible PIC family for programming in C? To put this into context, I have used C successfully with small projects, most notably with the 16F818, and also the 12F509 and 16F84. But I'm not an expert and appre...
