I've got a cheap PIC board off ebay. It all seems to work fine except the 7 segment displays. I can display numbers upon the first one only or all four together but not separately. I imagine its something to do with lighting one display at a time for a few milliseconds and cycling through them using software.
I've attached the schematic. I cant see how it would work as both IC's are connected to the same PIC pins.
anybody have any idea how it can be done?
