According to the output window, it seems like I upload a sketch now, but it don’t seem to work.
I got no clue what may be wrong. Can it be that some of the basic functions do not work like
pinMode, digitalWrite, delay ?
I looked in the documentation for the board regarding the on board LED, called LD2. It states:
LD2 USER
This green LED is a user LED connected to STM32G4 I/O PA5 (SB6 ON) corresponding to the ARDUINO® D13. To light LED LD2, a high logic state “1” must be written in the corresponding GPIO PA5. A transistor is used to drive the LED LD2. LD2 consumption does not impact the VDD STM32G4 power measurement, since LD2 is isolated from it.
So instead of LED_BUILTIN, I tried to use D13. But it did not change anything. This is then the blink sketch:
/* Blink Turns an LED on for one second, then off for one second, repeatedly. Most Arduinos have an on-board LED you can control. On the UNO, MEGA and ZERO it is attached to digital pin 13, on MKR1000 on pin 6. LED_BUILTIN is set to the correct LED pin independent of which board is used. If you want to know what pin the on-board LED is connected to on your Arduino model, check the Technical Specs of your board at: https://docs.arduino.cc/hardware/ modified 8 May 2014 by Scott Fitzgerald modified 2 Sep 2016 by Arturo Guadalupi modified 8 Sep 2016 by Colby Newman This example code is in the public domain. https://docs.arduino.cc/built-in-examples/basics/Blink/ */ // 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_BUILTIN, OUTPUT); pinMode(D13, OUTPUT); //digitalWrite(D13, HIGH); // turn the LED on (HIGH is the voltage level) } // the loop function runs over and over again forever void loop() { //digitalWrite(LED_BUILTIN, HIGH); // turn the LED on (HIGH is the voltage level) digitalWrite(D13, HIGH); // turn the LED on (HIGH is the voltage level) delay(1000); // wait for a second //digitalWrite(LED_BUILTIN, LOW); // turn the LED off by making the voltage LOW digitalWrite(D13, LOW); // turn the LED off by making the voltage LOW delay(1000); // wait for a second }
The LD2 LED remains off. I also tried to press the reset button.
When I powered the board first time, perhaps a blink program was in the MPU already ab fabric, because this LED did blink. So the LED do work. When I uploaded this blink sketch, the LED became off all the time.
What do you think I should do to debug this case?
