cupi's Issues

Documentation

Is there any documentation?

the link in the readme doesn't work
when going on docs.rs, there is no comments, only function signatures

I've read the examples, there are parts I don't fully understand.

For instance, is this comment supposed to enlighten the reader about some functionality or has it been put here for debug purpose (I don't know what export does)?

    let cupi = CuPi::new().unwrap();
    let mut pinout = cupi.pin(0).unwrap().high().output();
    //let mut pin = cupi.pin_sys(0).unwrap();
    //pin.export().unwrap();
    //let mut pinout = pin.output().unwrap();

FYI: Just published a crate using CuPi!

Just wanted to leave a note to let you know that I published https://crates.io/crates/cupi_shift last night which uses your excellent lib. Thanks to you I'll now have a Rust-powered holiday lights display =)

Incorrect revision-detection in cupi/src/board.rs

Hello,

I just noticed that the // old way code at the bottom of cupi/src/board.rs is wrong.
I'm not a Rust programmer, but it seems to be treating revisions "0005" and "0009" the same (RaspberryModel::B) but if you look at http://elinux.org/RPi_HardwareHistory you can see that "0005" is indeed a Model B, but "0009" is actually a Model A! And you make a similar mistake with "0007" (again, Model A and not Model B)

And less importantly, "000f" (made by Qisda and not Egoman) and "0014" (made by Embest and not Sony).

BCM2835 is not supported

Raspberry Pi comes with BCM2835, but CuPi lists BCM2708 and BCM2709.

The enumeration in board.rs should be expanded to include BCM2835.

Cannot compile cupi in my project - transitive dependency problems?

I'm trying to compile the blink example project on my Raspberry Pi Zero W, but the build command fails as it tries to compile cupi. I'm getting this terminal output:

If you want more information on this error, try using "rustc --explain E0432"
error: Could not compile `cupi`.

I'm still very much a Rust noob, so does this mean I'm having problems with dependency versions within nix, libc, and ioctl? Should I try to pin one of these versions in my lockfile, or is there something else I should try?

Thanks!

Raspberry pi zero support

Are you planning on supporting it?

How to set GPIO mode, e.g ALT0?

I can't find anywhere in the docs how to change the mode of a pin, which I need for toggling between UART and other modes on Raspberry Pi 3B+.
