Examples

Let’s have a look at the blink example. It conisists of the source code blink.cpp

#include "Arduino.h"

// the setup function runs once when you press reset or power the board
void setup() {
  pinMode(LED_BUILTIN, 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
}

This looks like a standard Arduino sketch. Please note the following differences however:

The sketch file name must end with .cpp and not .ino
The #include "Arduino.h" is mandatory
You need to provide a CMakeLists.txt file

To build the example go to the pico-arduino/examples/blink directory and execute the build steps:

mkdir build
cd build
cmake ..
make

The result can be found in the arduino/examples/blink/build directory.

Here is the list of the provided examples using the Arduino functionality

The Pico has 2 processors, so here are the examples which use this Pico specific functionality:

Here is some other Pico specific functionality:

And now some more complex examples:
