How to remove PWM signal from the pin?

[Dystman]

Hello! I'm working with several digital servomotors and I need to deal with overload situation. In case when my servomotor stays in overload state for too long I need to turn off the servomotor. I don't want to power off them so I'm looking for a function to turn off PWM signal.

Currently, I'm using mcpwm_gpio_init() and mcpwm_init() functions. But i cant find deinit functions.

I've searched deeper and find out, that there are functions gpio_matrix_out and gpio_matrix_in which, on my thoughts, do the mapping of MCPWM unit to certain GPIO. But I've bumped into some signalIdx parameter which I do not understand.

Can you help me please not to burn all my servomotors? ))

you dont need to de-init the pin. just set the PWM to 0.

Thanks for answering, username!

I was trying to do this also, but functions mcpwm_set_duty_in_us, mcpwm_set_signal_low and several others do not work properly. PWM signal still present on GPIO. Can you show me the function to switch it off?

It may be useful to figure out why the mcpwm functions don't do what you expect, but to answer your initial question: you can use gpio_reset_pin() to disconnect a GPIO from a peripheral.

Thanx for helping!
