Running TX433 and RX433 RF modules with AVR microcontrollers

I am trying to interface an RF module with AVR ATmega 128. I found this code interesting, but I couldn't understand these two lines:

//define receive parameters

#define SYNC 0XAA// synchro signal

#define RADDR 0x44

There are better ways to encode data to avoid losing synchronization. The best known is Non-return to zero (NRZ). Also, check out Biphase encoding.

Without other information, I'll think you're using C or some C-like language.

define creates a so called macro, this means in your code every reference to SYNC for example is replaced by 0XAA

Hope this helps!
