ARM Embedded Tutorial - FPC and the Raspberry Pi Pico

The Raspberry Pi Foundation has released the Raspberry Pi Pico, a very cheap Microcontroller board with quite interesting specs.

More Details here:

Raspberry Pi Pico Specifications

To best use this tutorial you will need to buy (at least) two Raspberry Pi Pico, we will use one as a target and the second one as a debug probe. Do yourself a favour, invest $4 for a second device, being able to debug is worth so much more.

As the Pico is brand new and support for the board is a work in progress I'd recommend that you set up a dedicated installation of Lazarus and Free Pascal as you will need to use both trunk version of Lazarus and a specially patched version of FPC that includes the necessary adjustments so that FPC knows about the Pico. Also expect changes as we all learn along the way.

To install the required versions of Lazarus and Free Pascal please see here:

Now we are ready for our first Program, as practice in the embedded programming world we start with blinking the on-board LED:
