Huffman codes 1.In telecommunication, how do we represent a set of messages, each with an access frequency, by a sequence of 0 s and 1 s? 2.To minimize the transmission and decoding costs, we may use short strings to represent more frequently used messages. 3.This problem can be solved by using an extended binary tree which is used in the 2-way merging problem. the sourse code is to encode and decode the Huffman.

This is IR (Infra-Red) learn module for home automation system. It can learn IR codes from different IR remotes, and then execute any assigned actions controlled by learned IR remote. This project was developed using Keil 8051 compiler. Processor - Atmel AT89C51 Frequency - 22.1184 Mhz (described as OSC_FREQ in "timer.h") Timer 0 - system timer (used for timeouts and delays) Also, look in folder /doc for additional information about IR codes formats and codes from different manufacturers.
