Hi
Who know easy way to mesure volts with bild in analog comparator. I'll be very heppy if someone help me with schematic and or assembler or basic 8051 example file.

Here's a small project, where voltage is measured with two opamps, some resistors, capacitors and the INT0 pin.

I also remember that Atmel or Microchip had an application note about measuring voltage with an internal analog comparator.
