Using Serial1 TX as a GPIO (ATP) result in undefined behavior #403
Description
#define LED_BLINK 24
// the setup function runs once when you press reset or power the board
void setup() {
// initialize digital pin LED_BUILTIN as an output.
pinMode(LED_BLINK, OUTPUT);
}
// the loop function runs over and over again forever
void loop() {
digitalWrite(LED_BLINK, HIGH); // turn the LED on (HIGH is the voltage level)
delay(1000); // wait for a second
digitalWrite(LED_BLINK, LOW); // turn the LED off by making the voltage LOW
delay(1000); // wait for a second
}
No blink on pin 24
