[Emc-users] Raw tachometer input ?

2010-08-19 Thread Rick Calder
I'd like to hook up a tachometer sensor to my mill. My idea is to have emc2 count/process the input stream of pulses and display the rpm on a pyVCP dial. I've tried searching the archives, and cnczone, without finding info on how to implement this. Any ideas ? TIA, Rick
