Feig RFID integration

Feig RFID hardware integration and API for simple implentation and control.

This software is released under MIT license from Deichman Public Library.

Short description: This is a service that exposes a simple API to communication with FEIG hardware, either connected by USB, Serial or TCP. It encompasses the operations to read and write tags and AFI alarm on ISO15693 transponders using a FEIG device. It also wraps an HTTP eventsource endpoint for easy use by any browser app. In addition it allows for embedding any HTTP web page if included under ``./cmd/html` folder.

Installation and Requirements

go version 1.19 or later is required, as well as make and FEIG SDK drivers and header files for the expected system to run on (windows / linux 64bit or Raspberry PI). Header files feusb.h etc. need to be placed under drivers or in system header folders. Drivers need to be included under drivers/<architecture> or in system driver folders.

To build, e.g. for windows: run make build_windows

Usage

  -debug
    	turn on verbose logging
  -port string
    	port of http API (default ":1666")
  -library string
        the ISIL number of the library (exclusive country code)
  -wake
    	Keep inventory state and keep all transponders awake (default true)
  -axeHost
        host ip/name of a TCP connected Feig Axe in same network
  -axePort
        port of a TCP connected Feig Axe in same network

Application fires up a http server and mounts optional web content from ./html folder

API routes:

    /.status 	server status endpoint
    /events/    eventsource subscription

    /scan    	scan inventory once
    /start 		start scan loop (send to any connected EventSource client)
    /stop 		stop scan loop
    /write 		write to tags in range (param: barcode)
    /writetagbarcode  write to a single tag in current inventory (params: tagid, barcode)
    /alarmOff 	turn off AFI alarm on all tags in range
    /alarmOn 	turn on AFI alarm on all tags in range

Basic flow is:

• inventory is fetched and kept in memory either by polling /scan or by activating scan loop with /start
• barcodes can be used to fetch and present information, e.g. from spore
• at any time a current inventory can be
  • rewritten: all tags in range are written to using sequence number and number of tags (/write?barcode=1234567890)
  • desensitized: (/alarmOff)
  • sensitized: (/alarmOn)
• /.status will at any time display uptime status, current inventory and read success/failures
