Hi..

i'm using a optocoupler.. for making pulses...

but because of the fact i use the output as the emitter to switch my pin on / off..

i know that the voltage rise and fall...

is there a point where the micro doesn't know the state..???

i see it read a 1 realy fast 1,2volts..???

Some of the PIC input pins have schmitt trigger inputs, if you use one of those it should sort out any problems.
