This repository contains an implementation of a virtual microcontroller based on the Unicorn emulator, which is in turn based on QEMU. It also contains a port of MicroPython to that virtual microcontroller. Unicorn has a JavaScript version, unicorn.js, which is obtained by running Emscripten on the C version of Unicorn, and allows the virtual microcontroller to run in the browser. This then gives a full MicroPython port running simulated-bare-metal in a web browser.
For a running demo please visit https://micropython.org/unicorn
$ git submodule update --init
Firmware binaries can be customized in the unicorn directory.
$ cd unicorn
$ make CONFIG=pyboard
The web page may be built using
$ cd www-emu
$ make
In order to build without using gzip (For example when testing with $ python -m http.server)
$ cd www-emu
$ make nogzip
There is a critical bug in unicorn-engine which is addressed here. In order for full functionality apply the patch to a unicorn submodule within a unicorn.js repository and build normally.
