Arduino Example - Blink

Now that we have the board package installed, it's time to make sure everything was assembled properly and we can upload code to the Processor. We'll just do a simple functionality check with the Blink example to make sure the Processor is working properly and can accept code uploads.

Example - Blink

Blink is one of the built-in example sketches in Arduino. Open it by navigating to File > Examples > Basics > Blink. You can also copy the code below into a blank sketch if you prefer:


  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:

  This example code is in the public domain.


// the setup function runs once when you press reset or power the board
void setup() {
  // initialize digital pin LED_BUILTIN as an output.

// the loop function runs over and over again forever
void loop() {
  digitalWrite(LED_BUILTIN, 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
  delay(1000);                      // wait for a second

Next, select your board (MicroMod STM32) and the correct Port and click the "Upload" button. After uploading finishes, the blue STAT LED on the Processor should blink on and off every second.
