32 bit hex conversion in to decimal
Ideally this is how I would break down the problem,
First make a assembly routine that correctly displays a digit given the appropriate number - such as 5 produces a '5' on the LCD
Convert the integer number to a hexadecimal value using assembly - search the net, there are several examples.
By using integer division extract the digits in the reading on a one-by-one basis and pass this value to the display section of code.
Unfortunately my time is limited atm, and I cannot provide the actual code.
