Description
The below program should blink the built-in LED and and print "Hello, World!" to Serial every two seconds. On a Nucleo L432KC it does blink the built-in LED but it doesn't print "Hello, World!" to Serial. On a Nucleo F303K8 or Nucleo F411RE the program functions correctly, the built-in LED blinks and "Hello, World!" is printed to Serial.
void setup() {
pinMode(LED_BUILTIN, OUTPUT);
Serial.begin(9600);
}
void loop() {
Serial.println("Hello, World!");
digitalWrite(LED_BUILTIN, HIGH);
delay(50);
digitalWrite(LED_BUILTIN, LOW);
delay(1950);
}
