Hi all,
Has anyone got any ideas about where to get some C code to read a barcode?
Ive got a pen but dont know what to plug it to.
" I think I see a pulse for each black bar"
Decoding this is quite advanced - you have to cope with speed variations as the user sweeps the pen, possibly not sweeping in a straight line, imperfections in the barcode, etc, etc,...
You would be far better advised to get a "smart" pen that does the hard work for you.
You might try looking to Agilent (formerly HP) for chips to do this...
