Re: chip as switch
okay, so - i want to add the same functionality to all of the PBX ports.
when PB0 is set to 0, it grounds the current. when its not grounding the current the current flows through the resistor and out to where ever its going to be used.
not the problem here is that i can only use this on one port, because if i connect it to all, if one port grounds, no current flows, and i need 8 seperate ports in that sence, i have 8 different destinations for the current and i want the chip to send the current to one at a time.
say i want to send current out to destination 0, only that one destination gets the power, and the rest get nothing.
hope this explains it better
