Its a Pro Micro (ATmega32U4). How do i need to change this that it also prints to Serial1 (UART): #define print(...) Serial.print(__VA_ARGS__) #define println(...) Serial.println(__VA_ARGS__) void setup() { Serial.begin(9600, SERIAL_7E2); println(); println(F("Test")); println()…

Print to USB and UART at the same time

Robin2:
What's wrong with
Serial.println("my text");

Serial1.println("my text");

That you have to write everything twice...

@-dev, thanks that works.
