Hi, I'm Fomu! [This workshop](https://workshop.fomu.im/) covers the basics of
|
|
|
|
|
Fomu in a top-down approach. We'll start out by learning what Fomu is, how to
|
|
|
|
|
load software into Fomu, and finally how to write software for Fomu.

|
|
|
|
FPGAs are complex, weird things, so we'll take a gentle approach and start out
|
|
|
|
|
by treating it like a Python interpreter first, and gradually peel away layers
|
|
|
|
|
until we're writing our own hardware registers. You can take a break at any
|
|
|
|
|
time and explore! Stop when you feel the concepts are too unfamiliar, or
|
|
|
|
|
plough on and dig deep into the world of hardware.

# Developing the Workshop
|
|
|
|
|
|
|
|
|
|
The workshop is written in
|
|
|
|
|
[reStructuredText (rst)](https://en.wikipedia.org/wiki/ReStructuredText) and
|
|
|
|
|
[generated using Sphinx](https://www.sphinx-doc.org/en/master/).
|
|
|
|
|
|
|
|
|
|
It is hosted on [Read The Docs](http://readthedocs.org/) and currently uses the
|
|
|
|
|
[Material Design style](https://material.io/) developed by Google through
|
|
|
|
|
[a slightly custom version of the `sphinx_materialdesign_theme` package](http://github.com/SymbiFlow/sphinx_symbiflow_theme).
|
|
|
|
|
|
|
|
|
|
It uses the [`sphinxcontrib-session` extension](https://github.com/mithro/sphinxcontrib-session)
|
|
|
|
|
to properly highlight the example sessions and to allow copying only the
|
|
|
|
|
session lines.
|
|
|
|
|
|
|
|
|
|
Other sphinx extensions which are used include;
|
|
|
|
|
- [`sphinxcontrib-verilog-diagrams`](http://sphinxcontrib-verilog-diagrams.rtfd.io/)
|
|
|
|
|
to generate nice diagrams from Verilog examples.
|
|
|
|
|
|
|
|
|
|
- [`sphinx-wavedrom`](https://github.com/bavovanachte/sphinx-wavedrom) to
|
|
|
|
|
generate [nice waveform diagrams](http://wavedrom.com/).
|
|
|
|
|
`sphinxcontrib-wavedrom`?
|
|
|
|
|
|
|
|
|
|
- [`symbolator`](https://kevinpt.github.io/symbolator/) to generate block
|
|
|
|
|
level diagrams from Verilog examples.
|
|
|
|
|
|
|
|
|
|
- [`sphinx_tabs`](https://github.com/djungelorm/sphinx-tabs) to support tabs
|
|
|
|
|
for different Linux / Windows / Mac OS X instructions.
|
|
|
|
|
|
|
|
|
|
