So, while waiting for parts to arrive, I have been diddling sketches on an A4 piece
of paper, on how to design the the minimal cost attenuator, for the PIC scope I am planning.
Now I peaked at one scope I have here, and it has an 11 position switch
10mv, 20 mV, 50 mV, 100 mV, 200mV, 500mV, 11V, 2V, 5V, 10V, 20V
Now that sucks in a way, as counting to 5 is very difficult,
as we all think binary these days ;-)
You could make the attenuator steps user programmable through some setup
menu.
BTW, why torture yourself with a PIC, when you can get a cheap LPCxxxx
ARM that can be programmed in C ?
The PIC can be programmed in C quite easily too, didn't you know?
Only masochists write entire programs in assembler these days.
