Hi Carl & Volhout
Thanks for the posts. I was blatantly unaware of the PIO stuff.
I have the need to measure low frequency stuff as well & I've got the 2 PIO channels going measuring frequencies OK.
@Volhout. The only issue I have (so far) is that if the inputs drop off or become disconnected, the PIO still puts out readings, normally the same frequencies.
Is there a way of inhibiting the output (or something else) if there is no signal input? My immediate solution is to monitor the inputs with other input pins set to PIN (or FIN) to check that there is a signal there or not.
Again, thanks.
Brian
