ESP32-S3 log to non-default UART pinsby ihabawad » Tue Mar 12, 2024 5:01 am Greetings, I am using ESP-IDF with an Adafruit Qt Py ESP32-S3, which has the following pinouts: https://cdn-learn.adafruit.com/assets/a ... pdated.png I would like to redirect the standard ESP_...
Description of Change ESP32-P4 has UART default pins only for UART0 and UART1. This PR allows the board definition from pins_arduino.h to define RX2 ... RX4 and TX2 ... TX4 if necessary. It also so...

Initializing ESP32 UART in Arduino IDE We use the HardwareSerial library when working with ESP32 UART communication using UART1 or UART2 ports. So, firstly include the library in the script. #include <HardwareSerial.h> Next, if we use Serial.begin(), then pins 1 and 3 are used, which...
