pwm_chan_t Struct Reference

PWM channel. More...

Detailed Description

PWM channel.

When using a general-purpose timer for a PWM device, the outputs OC<n> of each of the four capture/compare channels can be used as PWM channel. The respective capture/compare channel is then specified with 0...3 in cc_chan for the outputs OC1...OC4.

Advanced timers like TIM1 and TIM8 have additionally three complementary outputs OC<n>N of the capture/compare channels, which can also be used as PWM channels. These complementary outputs are defined with an offset of 4, i.e. they are specified in cc_chan with 4...6 for OC1N...OC3N.
