@ -26,6 +26,28 @@ Here is the command to build ESP32 + LittlevGL which is compatible with ILI9341
This make command will create ESP32 port of Micropython, and will try to deploy it through USB-UART bridge.
`LV_CFLAGS` are used to override width height and color, for ILI9341 compatibility.
### For JavaScript port
You need Emscripten installed and working. There are lots of guides about that on the web, but here's the [official one](https://emscripten.org/docs/getting_started/index.html).
Once you have Emscripten working, you also need to install the `clang` package:
1. `cd <path to emsdk>`
2. `./emsdk install clang-e<sdk version>-64bit # for example: clang-e1.30.0-64bit`
3. `./emsdk activate clang-e<sdk version>-64bit`
Now you can build the JavaScript port.
1. `cd <path to lv_micropython>`
2. `. ./emsdk_env.sh`
3. `git checkout lvgl_javascript`
4. `git submodule update --init --recursive` (*can be very important!*)
5. `cd ports/javascript`
6. `make`
7. Run an HTTP server that serves files from the current directory.
8. Browse to `/lvgl_editor.html` on the HTTP Server.
## Super Simple Example
First, LittlevGL needs to be imported and initialized
