IRTX

$34.95


Key Chain Infrared (IR) Remote Control Transmitter Development Kit
Control virtually any Infrared device by transmitting the proper code from IRTX. An Atmel AVR ATMega88V(P) is the heart of this transmitter. Write your own code to transmit any command to any TV, VCR, and any other Infrared enabled device.
Software Tools
Compiler Compile and build your code using the Free GNU GCC compiler tools for AVR. GCC on Linux You will also need C libraries Clib for GCC WinAVR GCC for Windows Download Example source code Source code in C to demonstrate how to send IR commands to an Olevia Syntax LCD TV. irtx.source.tar.bz2 Programming software Programming software is used to communicate with Programming Hardware to send compiled code to the microcontroller. Any programming software that supports the ATmega88V(P) will work. UISP AVR In-System Programmer
Hardware Tools
Programming hardware Programmers are used to download compiled code into the microcontroller. Any programming cable that supports the ATMega88V(P) will work. AJBMV ByteBlaster MV cable Remove CR2032 when ISP supplied power is connected so current doesn't back flow into the battery. CR2032 are not chargeable. Just like any other battery types, charging non-chargeable batteries can result in injury.
