ESP32 AnalogRead() Quote Postbylduprat»Mon Sep 10, 2018 8:01 am I am trying to write on a the pin 25, and I need to control the voltage with the pin 36. To do so, I am using the following code : Code:Select all intconsignePin =25;intcontrolePin =36;intledPin =5;intfreq...
https://github.com/espressif/arduino-esp32/issues/220 My preferred solution would be, if we had a DMA supported adc. Automatic continues adc (with cycle time, and number of chanels, as a parameters) via DMA. Independent from the CPU. The only CPU time we use, is , to read the memor...
Hello, I am currently programing an ESP32 C3 devboard which has multiple ADC channels and i would like to read data from 3 different sensors. The problem is that whenever i use analogRead() with any port it always only shows the measurme...

Hi, I checked yesterday the new implementation of analogRead and values are pretty incosistent. Not sure if it is because of the implementation of the method or just because the ADC on ESP32 is not very accurate. I created a simple sever...

What version of arduino-esp32? I recommend setting your voltage divider so that your output voltage runs in the range 0.4-0.8V (10K/2K2, then do the math to get back to the real value). This is in the linear measuring range of the ADC at the lowest attenuation (0db). The following...
