Any interest in adding an example that lets a user exercise microcontroller I/O from the console?

[potto216]

I have a program I'm working on in a fork of libtock-rs https://github.com/potto216/libtock-rs/blob/c3872d49b1a86600f9c6ce4f323c8548bdaf83e7/examples/signal_generator_cli.rs that allows a user or Python script to manipulate an embedded device's I/O from the console. So, for example if a user wants to send the bytes 0x01, 0xaa, 0x03 over the SPI interface they would type over the console

spi tx aa

and the console would reply

OK spi tx tx_len=3 truncated=0 tx=0x01aa03

and over the spi port one sees:

I'm currently testing the code for the other I/O. If there is interest let me know otherwise, I am going to create a separate repo for it and link it to libtock-rs, but I'm not sure how to do that.

Since it sounds relatively self-contained, I think it could reasonably be an example.

An external repository works too though, and might be a better fit if it ends up being large/complicated. As for linking it to libtock-rs, here are a couple suggestions:

1. git dependency in Cargo.toml.
2. git submodule. These are quite confusing to anyone who is unfamiliar with them, but if you find that you want to make changes (PRs) to libtock-rs to support your application then submodules make that easier.

@jrvanwhy I created a PR #594 for feedback.
