Further information of my question, is that I just want the TX port (pin) of the XIAO to be even parity and not its USB Serial emulation.

Yes, this is my description, and so I asked for alternation of any possible system setup method.

And I really wish the Espressif will consider to extend the overloading of the method Serial.begin( ) as it is a too narrow function for XIAO S3.

Hi, the error can be simply inputted as shown: #include "Arduino.h" void setup() { // put your setup code here, to run once: Serial.begin(115200, SERIAL_8E1); } void loop() { // put your main code here, to run repeatedly: } Here is the error: C:\Users\send2\AppData\Local\Temp\.arduinoIDE-unsaved2024...

Hi, I have an XIAO ESP32 S3 board and Iwould like to enquire how to set the serial port with SERIAL_8E1 in Arduino IDE, it's first seem to me a simple job as I can set it in ESP32CAM as Serial.begin(115200, SERIAL_8E1), but, when I changed the Board type to "XIAO_ESP32S3" in the IDE, this function d...
