EL5101 encoder interface was created by papagno-source
Hi at all.
I wanted to ask if anyone has ever tried to use an el5101 encoder card to do spindle orientation and read the position value. In the documentation I read that there is a PDO where to read the position, but I did not understand how to reset the counter when the zero mark of the encoder is hit. Can you help me ?
Thanks

this is handled like homing on index.
for sensor on the external latch input
set the "enc-index-ext-pos-enable" or "enc-index-ext-neg-enable" pin
for sensor on the C Line from the encoder
set the "enc-index-c-enable" pin
if the zero event ocoured the card sets its internal counter to zero or to the pos
you told with the set_raw_count_val pin and clears the enc-index-xxx pin.

i am talking about the native el5101 driver.
Module name is "EL5101"

Ok thanks, about scaling the position value , use some component or another pin the el5101 driver ?
Exist some hal example for pin connection ?
Again more thanks

enc-pos-scale is the scale pin. (increment per machine unit)
github.com/sittner/linuxcnc-ethercat/blo...er/src/lcec_el5101.c
there all pins are listed. line 75-95
