Run LittlevGL via PlatformIO

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 PC (via SDL drivers).
3. It has example, how to make multiple build targets. For example:
   • native to quickly prototype interfaces on PC
   • other, to build firmware for bare metal

How to install & use demo

Important! native build (emulator with SDL2 drivers) was tested in linux only! But you still can build MCU targets. If anyone interested to improve other OS support (Windows, macOS) - PR welcome.

Install Visual Studio Code

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

Install SDL drivers

Linux (Ubuntu, Debian, ...)

sudo apt-get install gcc-multilib g++-multilib libsdl2-dev:i386

Note:

• We use 32-bits build for more correct memory stat info. You can disable this in platformio.ini (see comments inside), and use libsdl2-dev instead.
• If you have conflicts on libsdl2-dev:i386 install, remove 64-bits version and dependencies first.

MacOS

Use Homebrew:

brew install sdl2

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.
3. Build / execute:
   • Simulator: Terminal -> Run Task... -> PlatformIO: Execute (native)
   • Bare metal: Terminal -> Run Build Task... -> PlatformIO: Build (stm32f429_disco)
