idp8 - Infrared Data Protocol 8

Abstract

Assembly implementation of a 3 bit IR data protocol for the AVR ATtiny85.

Firmware Features

1. Variable 38 kHz IR transmitter burst time (protocol independent)
2. Pulse delay encoding
3. TX error detection
4. High noise immunity
5. Uses internal 8 MHz RC oscillator
6. Timer resolution of 100 μs
7. Fully configurable and extensible

Warnings

The sample protocol provided is only intended to be used by one TX/RX pair.

Note: The addition of multiple transmitters may cause data corruption or other unknown side effects!

Info

Included in the main source files is a LED demo.
Four LED's can be controlled remotely using four tacticle push-buttons.

Schematics for the project are provided.

Folders:

• /firmware - TX and RX AVR firmware
• /schematics - circuit schematics for IR, TX and RX
• /spec - IDP protocol specification
