How to input Motor Fault signal?

[terjeio]

The signal has to be added to the driver.c input pin handling code (in several places).

Okay. Thanks.

Hi @terjeio
Thanks for your continuous support. I got the Motor Fault signal working with changes in driver.c as instructed. Now I want to invert the signal. My present $14 setting is 78, so I have to add 256 to it (as motor fault is on bit 8) which makes it 334. But somehow, it doesn't accept $14=334 with a message "Error 52: undefined". Any clues?

You have to tell the core that the signal is available here by adding:

hal.signals_cap.motor_fault = On;

Hopefully this will work...
