mplab help

Hi guys,
i need your help,how do i convert a hex to decimal using MPLAB assembly language?

Added after 2 minutes:

oh,forgot to mention. How do you convert FE to 254 with each digit in a different register?because i want to display it LCD
 

using mplab

When the data is stored in the main memory it is stored in binary, not hex
 

c convert to hex mplab

Hi,
I don't think there is a conversion module in MPLAB.

But using the Assembly Editor of MLPAB numbers can be represented in HEX or DECIMAL. For example: 0x10 (HEX) is equivalent to .16 (DECIMAL, don't forget the dot before 16 !!!)

Is that what you wanted?

I would convert your number to BCD format..

BCD is good for this because it sort of extracts each individual digit - so you can easily convert each digit to ASCII or what ever.
 

binary coded decimal conversions with mplab

owh,i think you guys misunderstood..

i want help in designing a program that produce ten base output so that the seven segment produce an appropriate number.

since the result in programming produce a hex base,how do i write a program to convert the hex base to ten base?
 

convert asm to hex using mplab

Hi,

If want to display a value that is in hex as a decimal value on a seven segment led the easiest way is with a Lookup table.

Have a look at this tutorial for a multiplexed 7 segment array, it might be of general help to you, if you download the lessons zip file the code contains the full lookup table .
