Hello

Can someone advise how I can extract the first 8 bits and last 8 bits from a 16 bit integer.

for example decimal 64339 = 11111011 01010011

I need the 1st 8 bits decimal 251 (11111011) and then the last 8 bits decimal 83 (01010011)

Can you give me an example of how to write this in C

Thanks

Hi Codey,

Just mask them off;

   int  Value, Upper, Lower;

  Value = 64339 ;
  Lower = Value & 0xFF;
  Upper = (Value >> 8) & 0xFF;


Good Luck,
Kent
