1. Forewords

The goal is to restore the original demo application which come with the EvB4.3 boards. Unfortunately, the resulted code is not optimized and will require at least ATmega32 micrcontroller inserted on the board.  But don't forget that the entire set of tutorials for this board, using Arduino language, are for the ATmega644P micrcontroller. Of course, the application can be written on other compilers/languages and can be much smaller and faster.

2. Setup the board

4. The Result

The green LED indicate when an IR code is received. On LCD are displayed date, time, temperature and RC5 IR code.


And with this, our fist target is achieved!!!
