I wrote a simple sketch that essentially lets the buildin LED blink through the loop method. At the moment I include LinkedList.h evering breaks and the Arduino does not exit setup-method (visible via the not flashing LED).
My test code:
#include<LinkedList.h>
void setup() {
// put your setup code here, to run once:
pinMode(LED_BUILTIN, OUTPUT);
}
void loop() {
// put your main code here, to run repeatedly:
digitalWrite(LED_BUILTIN, LOW);
delay(1000);
digitalWrite(LED_BUILTIN, HIGH);
delay(1000);
}
