Hi at all,
i'm working to make alive my bigboard 1. It has input for a parallel
keyboard so I'd like to build or to know where to find an interface to
convert a ps2 keyboard in parallel way. Well here
http://www.rasmicro.com/FTP/an434.pdf there is a schematic to convert ps2 to
IIC way. What I asking for is:
1) Is there anyone who know the way to modify the assembly to make the
8xc751 working on its p1.0 to p1.7 output to generate a parallel ascii code
corresponding to the key pressed on the ps2 keyboard?
2) What could be the programmer to save the program onto the 8xc751?
