Compile to mpy

The gateway currently supports uploading .mpy file compiled from Python scripts. The specific steps are as follows:

Note

• A mpy-cross Web version is currently available, which compiles .py code into .mpy file via the web interface.

• The tool is a static page built with emsdk that runs mpy-cross via WebAssembly and JavaScript. Uploaded scripts are not stored.
