Re: ADC Voltage measurement is not right!!!

Was the voltage in the linear range ? Would you please give some details of the real voltage and the read value ? And what settings did you use to initialize and to read the voltage ? Here are some application examples of ADC module. https://docs.espressif.com/projects/esp-idf/en/latest/api-referenc...

Re: Help program

So, I think here are tasks for you to make your project run: 1. If you are going to Arduino(which is a good choice for new beginner), you need to run Arduino on your esp first. https://github.com/espressif/arduino-esp32#installation-instructions https://www.arduino.cc/en/Main/FAQ 2. To control the m...

Re: Inverting PWM signal on RGB Light

I think the best and easiest way to do that is to invert the GPIO output signal in esp32. Refer to func_out_sel_cfg register in components/soc/esp32/include/soc/gpio_struct.h. For example, if you want to invert GPIO18, you can use the following code to do that, after initializing light driver. GPIO....
