Run LittlevGL via PlatformIO

CI

This demo should help you to organize your project with awesome PlatformIO IDE.

  1. It automates installing everything - just open folder with this project in vscode, and agree to install all it offers.
  2. It contains working LittlevGL demo, runnable on both are metal and PC.
  3. It has example, how to configure PlatomIO.

How to install & use demo

Install Visual Studio Code

https://code.visualstudio.com/ - follow instructions there, if you don't have vscode yet.

Install SDL drivers

Linux (Ubuntu, Debian, ...)

Use one of options below:

# 64 bits
sudo apt-get install libsdl2-dev
# 32 bits
sudo apt-get install gcc-multilib g++-multilib libsdl2-dev:i386

Note:

  • Use 32-bits build for more correct memory stat info.
  • If you have conflicts on libsdl2-dev:i386 install, remove 64-bits version and dependencies first.

MacOS

Use Homebrew:

brew install sdl2

Note: On MacOS you need to include (uncomment in provided example platformio.ini file) these lines in your platformio.ini file to import the drivers:

  ; SDL2 includes
  !find /opt/homebrew/Cellar/sdl2 -name "include" | sed "s/^/-I /"
  !find /opt/homebrew/Cellar/sdl2 -name "libSDL2.a" | xargs dirname | sed "s/^/-L /"

If you get the following error on M-chip Mac with VSCode, you can add -arch arm64 to build_flags in platformio.ini or just run pio run -e emulator_64bits -t execute in the system Python environment. (pio should be installed in system Python first).

ld: warning: ignoring file '/opt/homebrew/Cellar/sdl2/2.30.1/lib/libSDL2-2.0.0.dylib': found architecture 'arm64', required architecture 'x86_64'
ld: Undefined symbols:
  _SDL_CreateRenderer, referenced from:
      _window_create in sdl.o
...

Windows

Use MSYS2

pacman -S mingw-w64-x86_64-gcc mingw-w64-x86_64-SDL2

Add the path to your Mingw-w64 bin folder to the Windows PATH environment variable (usually C:\msys64\mingw64\bin). See instruction, 4.

Install flasher drivers (optional)

If you plan to upload firmware & debug hardware, read notes in PlatformIO install docs.

Build/Run

  1. Clone this repository or download as zip.
  2. In vscode, open folder via File -> Open Folder... menu.
    • If you do it first time - agree, when it suggests to install PlatformIO plugin, and wait when PlatformIO then install build tools and package dependencies.

To build/execute, on PlafomIO tab expand desired env and click target:

Note, for emulator env upload also executes compiled binary.
