TMCM-1311 Reference Switch Input Pull-up

[FastRabbit]

Hi All

In the TMCM-1311 HW Manual it is stated that a pull-up resistor can be enabled/disabled by software.

How can I access this function? I found nothing in the PyTrinamic driver and also nothing in the TMCM-1311 Firmeare Manual.

Thanks in advance

This can be set using SIO 0, 0, 0/1:

• SIO 0, 0, 0 switches off the pull-up resistors
• SIO 0, 0, 1 switches them on

Thanks, that works now fro me.

But still, I can't find this in the TMCM-1311 Firmware Manual....

Id like to close this issue. Concerns regarding the firmware manual are beyond the scope of the PyTrinamic GitHub issue tracker.

Fine for me.
