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.
The MC68HC05K0 is a low cost, low pin countsingle chip microcomputer with 504 bytes of userROM and 32 bytes of RAM. The MC68HC05K0 isa member of the 68HC05K series of devices whichare available in 16-pin DIL or SOIC packages.It uses the same CPU as the other devices in the68HC05 family and has the same instructions andregisters. Additionally, the device has a 15-stagemulti-function timer and 10 general purposebi-directional I/0 lines. A mask option is availablefor software programmable pull-downs on all ofthe I/O pins and four of the pins are capable ofgenerating interrupts.The device is ideally suited for remote-controlkeyboard applications because the pull-downs andthe interrupt drivers on the port pins allowkeyboards to be built without any externalcomponents except the keys themselves. There isno need for external pull-up or pull-down resistors,or diodes for wired-OR interrupts, as these featuresare already designed into the device.
