Hi, I am using this code to vary duty cycle of pwm and is working fine // the number of the LED pin const int ledPin = 16; // 16 corresponds to GPIO16 // setting PWM properties const int freq = 5000; const int ledChannel = 0; const int resolution = 8; void setup(){ // configure LED PWM functionaliti...

Hi,
Seems was my mistake somehow(probably wiring) because when I started over on a clean board it worked. Even so, I noticed that esp32 cannot start if pin 12 is High, but I fixed the issue

Hi all, I am using a LOLIN32 board, v1.0.0 together with an arduino nano. ESP32 receive some data on serial from nano (using pins - 16,17), and also run in AP mode with a webserver on it. My issue is that I am not able to read a digital pin which I set as "INPUT", where actually I get LOW or HIGH fr...
