This module contains the Zerynth driver for ID-20LA RFID tag reader from ID Innovation. This is the ID-20LA, a very simple to use RFID reader module from ID Innovations. With a built in antenna, the only holdup is the 2mm pin spacing (breakout board available below). Power the module, hold up a 125kHz card, and get a serial string output containing the unique ID of the card.
Creates in instance of the ID20LA class.
serial_port – Serial port to be used (RX only). (i.e. SERIAL2) callback – Callback to be called whenever a tag is read. read_timeout – Milliseconds to wait when polling sensor. (Default: 100)
The serial communication is initialized using the specified serial port. The TX pin is not used since the communication is one-way only.
The callback must take exactly one argument, which will be the 10-bytes bytearray read from the tag. It is suggested to put the ID-20LA in ASCII mode to be able to decode the 10 bytes as 10 characters, refer to datasheet for further informations.
This method stops the reading from the sensor.
