ARM Embedded Tutorials

Overview

Tutorials for programming ARM microcontrollers with FPC and Lazarus. This applies, for example, to the STM32 microcontrollers and RP2040 (Raspberry Pi Pico) microcontroller.

Set up driver / cross compiler / IDE

STM32

• Introduction to STM32 and FPC - How do I set up FPC / IDE (MSEide) to program an STM32F103C?

Raspberry Pi Pico

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.
