Virgil Dupras 1a6a549857 Make the SPI Relay protocol support multiple devices
Working on programming AVR chips exposes a glaring omission in my
first design of the SPI Relay: not allowing multiple devices make
this task hard. I constantly have to unplug my SD card before, plug
the AVR chip holder, then play a bit, then unplug the AVR holder,
then replug the SD card...

My prototype for a SPI relay design is built, but I haven't tested
it yet. I need to adapt the code first, which is what I do here.

When the prototype is tested, I'll update the SDC recipe with a new
schema.

emul

This folder contains a couple of tools running under the libz80 emulator.

Requirements

You need ncurses to build the forth executable. In debian-based distros, it's libncurses5-dev.

Build

First, make sure that the libz80 git submodule is checked out. If not, run git submodule init && git submodule update.

After that, you can run make and it builds the forth interpreter.

Usage

The ./forth executable here works like the one in /cvm, except that it runs under an emulated z80 machine instead of running natively. Refer to /cvm/README.md for details.

Not real hardware

./forth doesn't try to emulate real hardware because the goal here is to facilitate "high level" development.

These apps run on imaginary hardware and use many cheats to simplify I/Os.

For real hardware emulation (which helps developing drivers), see the hw folder.
