i.MX RT1062: What is Force Out Logic setting on EflexPWM?

[kenji]

Hi All

I want to synchronize PWM and ADC for BLDC motor control.

And I want to know how to use FOURC_OUT trigger setting.
Does FORCE_OUT trigger setting use for control the timing of output trigger source?
In my case I want to use VAL4 compare for trigger timing.

Hello Kenji,

The FORCE_OUT signal is explained with a little bit more detail in section 55.4.1.7 of the Reference Manual.

In a typical application, software sets up the desired states of the output pins in preparation for the next FORCE_OUT event. This selection lays dormant until the FORCE_OUT signal transitions and then all outputs are switched simultaneously.

The Reference Manual provides the example of this feature for a brushless DC motor to illustrate its usage.

I hope that this information helps!

Regards,
Gustavo
