- * Driver for IRLCD : simple USB1.1 LCD + IR Receiver based on ATtiny2313 *
- **************************************************************************
- * Hardware from http://www.xs4all.nl/~dicks/avr/usbtiny/index.html : *
- * [USBtiny LIRC compatible IR receiver and LCD controller] *
- * Ths driver is based on LCD2USB software by Till Harbaum, adapted to *
- * USBTiny protocol by Jean-Philippe Civade *
- **************************************************************************
- *
- * The IR receiving par is compatible with IgrPlug protocol
- * and can be used from LIRC.
