Incrementing Help

[Srigopal007]

Now I have another question! What about the result. Will that be in hex form or a decimal representation of the hex value.

for example lets say do the following

counter = counter + $01 will the result in counter variable now have the HEX representation. or will it have the decimal representation.

Also lets say I do the following

PORTB = 128 'which is 1000000 in binary.
this means that PORTB.7= 1 while the rest of the pins in portB = 0

if I am not mistaken this is the same thing as saying PORTB = $80.

So basically it does not matter if you are incrementing in HEX form or Decimal form because the output will eventually be converted back to binary form.

It doesn't matter how you "view" the number (hex, binary, or decimal), the value is still the same. So, adding one is the same, whether you add one "in hex" ($01) or "in binary" (%00000001) or "in decimal" (1). You still just have "a number".

One thing that might help clarify this for you is to use the Calculator in Windows (if you're using Windows). Using the "Scientific View" (View >> Scientific), type in a number, then change the radio buttons to Hex, or Bin, or Dec. The VALUE hasn't changed, just the way it's represented.
