interface motor pwm - already supported and provided example?

[DL88AI88]

Hi there,

i wonder whether the interface motor PWM which is mentioned in esp_wroom32_datasheet v1.4 on page 9 is already supported. If so, is there any example of using the api and the provided timers?

Thanks for your answers in advance.

Best regards

Hi there,

is there any example or api description of (datasheet v1.5 page 10)

PWM0_OUT0~2 (shouldn't it be PWM0_OUT_IN0~2 ?)
PWM1_OUT_IN0~2
PWM0_FLT_IN0~2
PWM1_FLT_IN0~2
PWM0_CAP_IN0~2
PWM1_CAP_IN0~2
PWM0_SYNC_IN0~2
PWM1_SYNC_IN0~2

It is only said that AnyGPIOs *
Three channels of 16-bit timers generate PWM waveforms;
each has a pair of output signals.
Three fault detection signals.
Three event capture signals.
Three sync signals.

But how do they work together?

best regards

Is this video on ESP32 PWM of use to you?

There are no drivers/docs for epwm/mpwm yet but you can try ledc like nkolban shows

Hi there,

thanks for the hints.
Actually, I saw Neil's video about ledc pwm which is quite informative (as well as Neil's book is).
I read through the esp8266 reference manual as well for a motor pwm library.
Is there a special reason why this interface is not provided yet?
For me and many other potential customers motor pwm would be a great step forward for the esp32 of being a fully functional embedded device.
Maybe I can place some wishes for the library here :
one should define settings like
pwmmotor_frequency_khz (kiloHertz)
pwmmotor_frequency_hz (Hertz)
pwmmotor_period_s (seconds)
pwmmotor_period_ms (milliseconds)
pwmmotor_period_us (microseconds)
pwmmotor_pulsewidth_s (seconds)
pwmmotor_pulsewidth_ms (milliseconds)
pwmmotor_pulsewidth_us (microseconds)

This would be nice.

Any chance that we see an interface soon?
