What works

REQuest A
SELECT for single size UIDs

TODO

[x] Make sure this works with the spidev crate (i.e. with the Raspberry Pi)
[ ] Anticollision loop -- SELECT works when there's only one nearby tag
[ ] Authentication (MFAuthent)
[ ] Reading / writing data into the tag
[ ] Configurable timeout
[ ] Make the API non-blocking and compatible with the interrupt pin
[ ] Support double and triple size UIDs -- I don't have hardware (tags) to test this.
???

Examples

There's an example for the Raspberry Pi (3) in the examples directory. The example turns an LED on when a card is nearby and turns it off when a tag in nearby. There's a video of the example [here]. To reproduce the example you'll have to tweak the values of the card and tag UIDs (Unique IDentifiers).

The same example has been implemented for the [Blue Pill] development board. You'll find the code for that example in [this branch] of the blue-pill repository. If that branch is gone, check the master branch.
