Actually, the whole instrument seems as a pretty clever design. I think
that I will try to build one, just for fun. It is only pitty, that there is
no .ASM file included. To retype the whole program from PDF file will be
pretty boring.

The only thing which I am missing in this system is some kind of I2C
protocol analyser. But maybe with bigger PIC, this function can be added.
