although i do have one question, what does the F() do inF("raw: ")It is a macro that ensures that constant strings are kept in flash memory (32 KBytes), and not loaded into SRAM. you only have 2048 bytes of SRAM, and every character takes up a byte. the F() macro ensures that only 1 character at a time is loaded from flash into RAM before being passed to the UART.
