Me again,

I've bough a Gameboy Camera, which I want to use for robotic vision, it's got an analog output for each pixel, clocked out by an I/O line. This Analog signal comes out between 0-2 volts.

As I'm memory deficient already, I don't want to use an A2D then see if the value is over 128 for black othwerwise it's white, I just need to boost the 0-2 volts up to 2-4 volts, so darker pixels will be logic 0 and light colors logic 1.

Can anyone point me in the right direct/tell me exactly what to do :-)


Many thanks

Chris Brooks.
