I am jumping into a project that has already been going for a while--other engineers have been working on it, but now I'm trying to help resolve some issues. I worked on a previous version of the same product (using a different microcontroller). In the older version I worked on, we used a counter chip to give us an edge after a certain number of pulses. When that edge was detected, the timer count would be latched automatically and I would come back later and read it, subtract the previous number from the new number and calculate frequency.
We are going for a board rev right now, and I want to make sure we have selected the right pin. We are running the output from the counter chip to R7. Should that work?
Thanks very much.
