Otherwise give me a mail.
The design is based around a PIC16F84 with several PCF8574's so called IO expanders.
The PIC does the decoding of the RC5 codes send from a standard remote control. Every Device, cd, TV, has its own 5bit address followed by the command, being volume up/down etc.
The decoded RC5 codes are here indeed used for volume control, channel control and steering of an LCD.
The RC5 receiver is a standard device which is sensitive to the particular 38KHz modulated code. The device just gives you serially what you've send.
The micro also decodes the rotaty encoders, also used for volume and channel control.
After decoding all the stuff and updating the respective variables it is send out via I2C to the io expanders.
These control relays for the volume and channel selection.
The SW is in C and written for the CC5X compiler.
The eval version lets you make code of 1k max. But that is enough in this case.
Via a PIC programmer (dont buy that expensive stuff, look for the taite programmer and SW) i download the code into flash.
And that is it folks.
