Arduino for STM32

Posted: **Mon Oct 04, 2021 7:26 pm**

Hi,

I'm using an NUCLEO F103 board and try to send monitor data over Serial1.

This works in setup:

void setup() {
	HardwareSerial Serial1(PA10, PA9);
	Serial1.begin(9600);
        Serial1.println("Testpoint 1");
       ......

but I have found no way to use Serial1 in other functions
or globally for classes in other files.

You have to define the Serial1 outside the setup function to be global else it is local at the function.

HardwareSerial Serial1(PA10, PA9);

void setup() {
        Serial1.begin(9600);
        Serial1.println("Testpoint 1");
}

Serial1 usage
