[Loadd]

I'm doing a BLDC drive with sensor.I want use PWM1 force funtion to switch all the output at the same time. I choose Force_External , it's done a half , becasue I found only rising edge of Extforce can switch.Dose anyone know if it's true that only rising edge of force is valid>

Hello @Loadd,

You can change the polarity using the XBARA_SetOutputSignalConfig after configuring the input for the FORCE_EXT? If you want to check how to use the API you can check the xbara example in the SDK.
