Hello all,

Can someone explain is 5A-75E board work now or still is work in progress as i presume
I wach this topic, but is quiet for some time..
I have two of this board so if someone need to test something i can do that..

github Peter-van-Tol is not updated from January, is it stoped development or is in other github project active??

github.com/Peter-van-Tol/LiteX-CNC/commits/main
 

Work on the project is in progress in another branch, github.com/Peter-van-Tol/LiteX-CNC/tree/...tensions-to-litexcnc
The way of configuration has changed: in this branch, the configuration is prepared during gateware (==the firmware of FPGA) compilation and upon start the driver fetches it from the FPGA. Also, the current state of firmware expects another structure of configuration JSON file. I appreciate any help regarding this issue as the new way of configuration is not documented yet.

Can anyone force (11-add-external-extensions-to-litexcnc) an encoder to work ?

Have you tried this?

Yes.
I got some hal pins but values not change when encoder acts.
I need working hal configuration.

some encoder needs pullup resistors

Most of encoders needs pullups.
These have built-in can burn 3.3 V inputs...
I always use pullups and Schottky diodes.
