[Emc-users] Encoder Index Support Survey

2014-01-26 Thread Charles Steinkuehler
I'm working on adding software encoder support to the BeagleBone PRU code. Counting up/down is easy, but I'm wondering how to deal with the index pulses. Both the Mesa VHDL code and the existing software encoder component have quite a variety of options, and I'm wondering if it is necessary to su
