C types understood by the gcc-avr compiler



Note:  The AVR microcontrollers are 8 bit devices, with a small number of 16 bit registers. 
The compiler will correctly handle 16 bit values, including writing pairs of 8 bit registers in the correct order.
However, beware of using 32 bit or larger register definitions - the compiler will probably do the right thing, 
but the delay and complexity in your code may be prohibitive.


Here is a list of C types, defined in the header inttypes.h

int8_t		8 bit signed value
uint8_t		8 bit unsigned value
int16_t     16 bit signed value
uint16_t    16 bit unsigned value




and the ones to avoid:
int32_t		32 bit signed value
uint32_t	32 bit unsigned value
int64_t		64 bit signed value
uint64_t	64 bit unsigned value
