Hello,
I have an unknown 4 segment (clock) LCD that was driven by a PCF8576CT. I've located the four baseplates and now need to identify the common segment pins for the LCD. So I just need a simple circuit I can use the output to discovery, thru trial and error, the segment pins on the LCD.
i.e. touching one lead to one baseplate and then touching the other lead to each of the other non-baseplate pins and noting which segments activate.
Thanks,
Rey
