Hi
I'm new to the STM32 board but not to Arduino IDE. I want to use two STM32 boards (with DXV lr30 900) for LoRa communication. I'm starting with a minimal program (without LoRa), just to see how the communication works between the STM32 and the Arduino IDE's serial interface. I can compile and download this program without any problems, but I don't see anything on the serial interface, whether using the ttyUSB0, ttyUSB1, or ttyS0 ports at 9600 baud.
here is the test program
void setup() {
Serial.begin(9600);
delay(2000);
Serial.print("hello");
}
void loop() {
Serial.print(".");
delay(1000);
}
Can anyone help me ?
Thanks in advance
