Ever wondered what extra things you could do if your TV remote control had extra buttons? This project allows you to send every possible code to your TV or other domestic devices, as long as it uses one of the 8 common protocols provided here

Added a version for Mikromedia for STM32 M4 board and ARM C compiler

10 July 2012

Connect pin 33 of MMB (or better still, battery boost shield) to a 100 Ohm resistor and IR LED in series to Gnd.

Then you can send any code in any of eight IR protocols to your TV, DVD player or other domestic device.

Connect a higher current driver circuit and use a high current LED (or two) if you want longer range

Common Sony TV buttons are the easiest to work with if you have a Sony TV, but you can choose your own protocol, frequency and bytes to transmit.

I have a Samsung TV, so you will see I have set up handy Samsung buttons.

You can experiment to see what extra functions your TV (or other device) can perform in addition to the functions that your remote control will give.

To put Sony TV into test mode use the yellow buttons: Sony service - send - Sony TV inf -send
Same process to exit Sony test mode

See the sbprojects web site for an explanation of domestic IR protocols

Serial to GLCD for EasyPIC7

I found a need to build my own serial GLCD (text only). Thought I might share it in case someone else had an interest. Demonstrates circular UART buffer with interrupt and simple use of GLCD for text.
