P.S. It seems as when I set the max duty cycle to 8192 - that made the "fade" work full scale (0% to 100% PWM). But that actually help reveal that the following code doesn't seem to be doing anything: printf("3. LEDC set duty = %d without fade\n", LEDC_TEST_DUTY); for (ch = ...

The esp32_technical_reference_manual is still very unclear about this, is there any additional documentation?

如题所说，ledc 配置如下, led pwm在light-sleep模式下没有PWM输出。 在切换rtc_clk_slow_freq_set(RTC_SLOW_FREQ_8MD256)后，PWM输出才正常，但是电流明显增大。 请问，是否可以在rtc_clk_slow_freq_set(RTC_SLOW_FREQ_32K_XTAL)条件下，进入light-sleep后正常工作？ // Prepare and then apply the LEDC PWM timer ...

The ESP32 series chips all have a GPIO matrix, which means that (with the exception of some very specific peripherals) you can route any peripheral signal to any GPIO. In practice, this means you can use any GPIO (that is not otherwise occupied) as a LED_PWM output.

I'm new in ESP32 and want to use the LED_PWM unit in the ESP32-S3 using ESP-IDF. I've read the document about it on this link. But I don't know which GPIOs can be connected to those PWM outputs. I just need a document with a table of ESP32-S3 ...

... to drive the mosfet). This video can give a good reference: https://www.youtube.com/watch?v=vudSUDFWoQE Try checking if when you kill the PWM output the servo goes to idle, if it does, you wont need any additional circuit, just use detach (if you are using the arduino library) or disable ...

Hi McEsp32
The FSESC and VESC do not use PPM, they use PWM. It's just named wrong in their documents.

I'm having issues getting PWM above 30khz, I'm using the Arduino Framework and using the LEDC functions. Resolution is 10bit and should be able to get 78khz. If I run the same code on standard ESP32 I can get the 78khz. So it seems to ...

Our control must can control the number of pulse and the frequency of output pulse at the same time.
So, can not use PWM and only can utilize the ISR of timer that priority is more high.
