  • Microsoft Word - HP-IR Receiver with Arduino.doc - HP-IR Receiver with Arduino.pdf
    A Hewlett Packard Infrared Signal Decoder
    Martin Hepperle
    June 2015
    Several Hewlett Packard pocket calculators are able to send printer output via Infra-Red (IR) signals to a small portable printer. They use an HP-specific transmission protocol which is also called “Red Eye”. This protocol is different from the better known IrDA protocol. This document gives a brief overview of the format and describes hard- and software to build a decoder system for this protocol.
    This system allows receiving the “Red Eye” signals with a computer via a serial or an USB interface.
