When I have added velocity estimation in hal_pru_generic, I have
validated with a python script and a wire between a pwmgen output and
the encoder input.
Results are here:

And the scripts are attached to

Hi,
On my side, I am using eQEP2 hardware encoder along with index.
It is able to manage high pulse rate. Mandatory because I have a 4096
ppr encoder at 6000 rpm: 400 kHz.
Not yet tested with a real threading, but validation I have done so far
by using a signal generator shows that the index

Hi,
Is any body else using the Pru encoder - I’ve been using it for spindle feed
back on my Lathe for some time now, but I’ve just come to do some thread
cutting and the index-enable isn’t being cleared on and index pulse.
I’ve double checked the hardware and the pulse is being sent to the
