gray code decode

Archiver

firstly, thanks to everyone who replied. I looked, nada.

maybe what I should try to do is just have a look up table in eeprom
and feed the stamp with the decoded binary since there is a finite
number of combinations used.

what do you think of this an which stamp would work best in this case.

thanks

nada? Here is an 8 bit gray code to binary routine:

gc var byte ' input gray code 8 bits
gc0 var gc.bit0 ' alias for lsb of gc
bn var byte ' output binary 8 bits
bn0 var bn.bit0 ' alias for lsb of bn
ii var nib ' index for conversion loop

gc=10110101 ' pick a gray code to enter here
' this number is just for a demo
' now start the conversion routine here
bn.bit7=gc.bit7 ' start with most significant bits
for ii=6 to 0 ' bit by bit XOR
bn0(ii)=bn0(ii+1)^gc0(ii)
next
debug bin8 gc,tab,bin8 bn,cr
' the result printed is the gray code
' and the corresponding binary code
end
