# idp8
`idp8` - `Infrared Data Protocol 8`

# Abstract
Implementation of a experimental `3 bit` `IR` data protocol on a `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! <br>

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

Schematics for the project are provided.

Folders:
* `/firmware` - `TX` and `RX` `avr-asm` firmware.
* `/schematics` - circuit schematics for `IR` `TX` and `RX`.
* `/spec` - `IDP` protocol specification.
