I need to convert a 32 bit binary number to gray code. i know how to do
it bit by bit, but i need to do a function to do it, so that i don't
need to repeat code 32 times. Can anybody help me?
Thanks

Mmm... It's quite some time I wrote 8051 assembler, but if memory serves
it's done like this:
num1 equ 64
num2 equ 65
num3 equ 66
num4 equ 67
clr c
mov a,num1
rlc a
xrl a,num1
mov a,num2
rlc a
xrl a,num2
mov a,num3
rlc a
xrl a,num3
mov a,num4
rlc a
xrl a,num4
end
