pwm_conf_t Struct Reference

PWM device configuration. More...

Detailed Description

PWM device configuration.

PWM configuration.

PWM device configuration data structure.

PWM configuration options.

Each device supports up to 4 channels. If you want to use less than 4 channels, just set the unused pins to GPIO_UNDEF.

Note
define unused pins only from right to left, so the defined channels always start with channel 0 to x and the undefined ones are from x+1 to PWM_CHANNELS.
