Hello

I am using 24bit adc interfacted to AT89s52. i am reading the output in 8bit formate i.e (low byte, mid byte, high byte) i want to integrate all the value into a integer value.i am using keil software.

low byte=33h
mid byte =04h
high byte =02h
i want to make the value as (value=020433h)

Re: Interger value

typedef unsigned char u8;
typedef unsigned long u32;

u32 combine( u8 high, u8 mid, u8 low )
{
   return ( ( (u32)high << 16 ) | ( (u32)mid << 8 ) | (u32)low );
}

...

/* do the conversion from bytes to long */
u32 result = combine( 0x02, 0x04, 0x33 );
