PLL with a PIC16F876A
PostPosted: Thu Mar 01, 2007 3:49 pm     Reply with quote
Hello,
I would like to detect a frequency of 440Hz with a PIC16F876A. For this I want to implement a PLL in my PIC. This implementation will be done in C with CCS.
Can you help me?

Thank you
Guest

There are plenty of people able to help but, with a generic question like that, few will be willing.

Do you have any specific questions that you would like answered?
