+# LVGL web simulator project with EEZ Studio
+
+## How to get started
+
+### Install SDL
+
+Downlad [SDL](https://www.libsdl.org/) (a graphics library to open a window and handle the mouse). On Linux:
+1. Find the current version of SDL2: `apt-cache search libsdl2 (e.g. libsdl2-2.0-0)`
+2. Install SDL2: `sudo apt-get install libsdl2-2.0-0` (replace with the found version)
+3. Install SDL2 development package: `sudo apt-get install libsdl2-dev`
+4. If build essentials are not installed yet: `sudo apt-get install build-essential`
+
+### Install Emscripten SDK
+Download the [Emscripten SDK](https://kripken.github.io/emscripten-site/) and make sure it is in your PATH.
+
+1. `git clone https://github.com/emscripten-core/emsdk.git`
+2. `cd <path-to-emsdk>`
+3. `git pull`
+4. `./emsdk install latest`
+5. `./emsdk activate latest`
+6. `source ./emsdk_env.sh`
+
+More info here: https://kripken.github.io/emscripten-site/docs/getting_started/downloads.html
+
+### Build the project
+1. `cd C:\work\eez\native-interface-lvgl-no-flow`
+2. `mkdir build`
+3. `cd build`
+4. `emcmake cmake ..`
+5. `emmake make -j4`
+6. A file called `index.html` will be generated. Run this in your browser.
+
+#### Known issue with Google Chrome browser
+Chrome can't open the generated html file offline. It works if you copy the files to a server. Use Firefox or other browser for offline testing.
+
+#### Known issue with Firefox
+Firefox can't open the generated html file offline unless you go to `about:config` and change `privacy.file_unique_origin` to `false`.
