I wonder if this will be corrected or if arduino usesrs will be limited to one serial on the ESP32S2 for eternity?

How do you explain this works? #include "driver/uart.h" // ESP32S2 usb cdc on boot on, usb dfu on boot off, upload mode internal usb. const int VEBUS_RXD1=13, VEBUS_TXD1=12; const int VEBUS_RXD2=10, VEBUS_TXD2=11; const int UART_USED1 = 0; //UART_NUM_1; // serial1 const int UART_USED2 = 1; // serial...

Me thinks console, serial0, is not uart but usb.

I did read with esp-idf both serial do work. Seems an arduino-ide problem.

Serial == Serial0 (aka the default console). <-- not hardwareserial, but USB Serial1 == HardwareSerial(1) Serial2 == HardwareSerial(2) <-- this one not working in arduino ide I interpret "2 uart" as "2 hardwareserial". See "uart" here: https://docs.espressif.com/projects/esp-idf/en/v5.0.2/esp32s3/hw...

This compiles, has outpunt on pin 12 but no output pin 11 #include <hardwareserial.h> HardwareSerial Seriala(1); HardwareSerial Serialb(2); void setup() { Seriala.begin(9600,SERIAL_8N1,13,12); Serialb.begin(4800,SERIAL_8N1,10,11); } void loop() { Seriala.println("hello 1"); Serialb.println("hello 2"...

The S2 has usb plus 2 hardware uart. Serial usb Serial1 = hardware first Serial2 = hardware second Arduino IDE: void setup() { Serial1.begin(9600,SERIAL_8N1,13,12); Serial2.begin(4800,SERIAL_8N1,10,11); } void loop() { Serial1.println("hello 1"); Serial2.println("hello 2"); delay(100); } gives compi...

TY Explains it. In the main Arduino loop, above loop() function, in the file cores/esp32/main.cpp we see yieldIfNecessary() function. It works on ESP32-S2 for example as it only has one core. Function adds a 5ms delay every two seconds. Under some specific circumstances, this causes problem with loo...

The actual code is in the git link. It's: void loop() { debug_gpio = !debug_gpio; digitalWrite(MY_GPIO, debug_gpio); } The same code works glitch-free on the old esp32. Could this be an internal usb thing? Edit: I did test moving it to "task1" at priority 1. No 5ms gaps there. I do not understand it...

Basically this issue:
https://github.com/espressif/esp-idf/issues/10055

The ESP32S2 stalls every 2 seconds for 5ms.
This is very annoying when using it for a quadcopter with 2ms cycle time.

ESP32 and ESP8266 do not have that issue.

Works perfectly. TY

Next thing is mounting esp32cam on this:
