Can anyone suggest a quick and dirty circuit to detect if a voltage is rising or falling? (not fast changes) With 2 outputs for example so that 10=rising, 01=falling, 00=no change.
I'm thinking the input could charge a capacitor with a resistor connected across it, feeds an op-amp where it's in reference to a mid-point voltage. After that it seems to get complicated, maybe there's a better way?
