measuring frequency with a 16F628A PIC

After disappointing results measuring frequency with an Arduino due to the Arduino system interrupts stealing clock cycles, I tried a 16F628A PIC. This is a much more primitive chip. In my system it has only one job, to spit out a count of 4MHz main system clock cycles that have passed between the onboard comparator … Continue reading "measuring frequency with a 16F628A PIC"
