picOS

The Pico Operating System (pico + OS = picOS).

Introduction

I always wanted to start development on an ARM based chip, and the rp2040 is the perfect start. Thank you @klaxxon for creating rp2040os. With that project I wouldn't be able to learn that quickly about how the ARM cortex-m0+ model works.

The goal of this project is, to create a simple framework that allows for quick usage of both cores with different features of the scheduling process itself.

Getting started

Project setup

$ git clone https://github.com/oltdaniel/picos
$ cd picos
$ cd toolchains
$ wget https://developer.arm.com/-/media/Files/downloads/gnu-rm/10.3-2021.10/gcc-arm-none-eabi-10.3-2021.10-x86_64-linux.tar.bz2
$ tar -xf gcc-arm-none-eabi-10.3-2021.10-x86_64-linux.tar.bz2
$ cd ..

Manual build

$ mkdir build
$ cd build
$ cmake .. -DCMAKE_BUILD_TYPE=Debug
$ make

Example

The current example can be found in src/main.c.
