IR-remote protocols NEC, Samsung and Toshiba are very close. This subroutine decode it all.

Address & Command bytes is ready received data,
Ir_receive bit indicate a received data,
Ir_repeat bit indicate a repeat key for NEC or Toshiba. Samsung has not special repeated key - transmitted whole data again.
Ir_error bit may be used to recognize receiving error.
Ir_protocol = 1 for NEC,
Ir_protocol = 2 for Samsung or Toshiba.

Subroutine is adaptive, so IR clock could go beyond the standard and AVR clock may be from 1 to 64 MHz - you can even change the frequency on the fly.
In attachment example with SSD1306 LCD.

Mrshilov,

Thank you, is a very nice program, with a new approach, I like this solution, without frequency clock problems, and the best : multi-protocol !
