Hi Chris, I wonder if you could say a few things in general terms about how you adapted nonpareil to make use of your I/O hardware. The source tarball compiles to a GTK application, but I intend to interface to a physical keyboard and display over GPIO pins. Do I need to rewrite display.c and keyboard.c? Is there a command line interface to nonpareil? Thanks.
