Need help with addition, I guess
PostPosted: Wed Oct 03, 2012 8:56 pm     Reply with quote
i is a byte
value is a long 3
code is a long 0x0000

I'm checking the first digit in a 4 digit code to see if its 0, if so add 0x1000 value times and put the result in code. When I am done with this, code still printf's as a 0000. printf("%4x\r", code); when it should be 3000 if value is 3, right? Please help.
Code:

 if ((code && 0XF000) == 0)       // First Digit
  for (i=1;i<=value;++i)
   code += 0x1000;
  goto Getout;

Thank you,

Download the CCS manual:

Look in the printf section at the list of format specifiers that are
used to display the various data types. Find the correct format
string to display a "Hex long int". Then use it instead of what you
have above.
