PicoSystem C++ Boilerplate

This is a quick and dirty boilerplate repo to get you started quickly developing games for the PicoSystem.

Getting Started

1. Install the tool chain.

$ sudo apt update
$ sudo apt install cmake gcc-arm-none-eabi libnewlib-arm-none-eabi libstdc++-arm-none-eabi-newlib build-essential

2. Update the submodules. This pulls in Raspberry Pi's Pico SDK, Pimoroni's PicoSystem Sdk and pulls TinyUSB into pico-sdk.

$ git submodule update --init
$ cd pico-sdk
$ git submodule update --init
$ cd ..

3. Create the build folder and build hello-world. After making you'll be able to drag the build/games/hello-world/hello-world.uf2 into the PicoSystem when it's booted into DFU mode.

$ mkdir build
$ cd build
$ cmake ..
$ make -j8

Adding your own games

1. Create a new folder under games.

$ mkdir games/new-game

2. Create your game entry file in the new folder, the following can be used as a template.

#include "picosystem.hpp"

using namespace picosystem;

void init()
{
}

void update(uint32_t time_ms)
{
}

void draw()
{
}

3. Create a new CMakeLists.txt in the new folder, the following can be used as a template.

cmake_minimum_required(VERSION 3.13)

project({ProjectName})

picosystem_executable(
  {ProjectName}
  {GameFile}.cpp
)

pixel_double({ProjectName})
disable_startup_logo({ProjectName})

Replacing {ProjectName} with the name of the project and {GameFile} with the name of the file created in the previous step.

4. Add the new folder into the games/CMakeLists.txt

add_subdirectory(hello-world)
add_subdirectory({NewFolder})

5. Write your game!

6. Build your game. After making you'll be able to drag the build/games/{ProjectName}/{ProjectName}.uf2 into the PicoSystem when it's booted into DFU mode.

$ cd build
$ cmake ..
$ make -j8
