How can I turn on low side PWM idle state on STM Workbench?

Hi @SkyWork​ ,

Consider that having the low side MOSFETs always on during the idle state, means that the motor is always braked.

Then, be sure that the driver you are using has an interlocking function, to avoid cross conduction.

It means that even if you set both the HS input and the LS input high, the drivers do not turn on together.

In general it is better to have all the power stage off during the idle state.

So, to avoid any potential issue, the #error directive is inserted in the code whenever you try to change the idle state.

However according to the motor driver used it is possible to use the idle state high for the low side.

Which driver/evaluation board are you using ? Can you share the part number ?

You can check on your board what described above and if you are ok with it, create your project as you have already done, changing the "Low side PWM idle state" from "Turn-off" to "Turn-on".

After code generation you can just comment the line:

#error "Error: LOW_SIDE_IDLE_STATE in driver_parameters.h must be false (TURN_OFF)."

Try to to compile and download the code and let me know if it works.
