• "NuttX RTOS for PinePhone: Feature Phone UI in LVGL, Zig and WebAssembly"

• "(Possibly) LVGL in WebAssembly with Zig Compiler"

See nuttx-build-files.zip below for the NuttX Build Files that are required for building the Zig LVGL App for PinePhone and WebAssembly. (Assuming we're not building NuttX from scratch)

Bundled with the NuttX Build Files is the Source Code for LVGL 8.3.3. Which will be used for building LVGL for PinePhone and WebAssembly.

The NuttX Build Files were created with these commands...

git clone https://github.com/lupyuen/pinephone-nuttx
git clone https://github.com/lupyuen/pinephone-lvgl-zig
git clone https://github.com/apache/nuttx nuttx
git clone https://github.com/apache/nuttx-apps apps
cd nuttx
tools/configure.sh pinephone:lvgl
make
