cf_rh320u_93_reader

Current Crates.io Version

Rust library for interaction with Chafon CF-RH320U-93 USB card readers. It's an open source implementation of the official library, which can be found on their website.

Features

  • Read and write ISO 15693 cards
  • Control buzzer and LED
  • Set and get internal serial number
  • And other commands

The main goal is to support all ISO 15693 related commands in the future.

Usage

First you need to open a device connection via open method of CFRH320U93 struct. Then you can call the desired method.

use cf_rh320u_93_reader::*;
let device = CFRH320U93::open()?;
let inventory = device.iso15693_inventory()?;
for card in inventory {
    println!("{:?}", card);
}

If something goes wrong, ReaderError enum is returned. It contains either a UsbError (which means that there was a connection error), or either a CommandError (a status code returned directly from a reader).
