I am considering using an MCU that has built in LCD drivers, but it only implements 1:8 multiplexing. In other words, it has eight "common" lines that are sequentially asserted. I need to connect it to an eight character seven segment display. None of the displays that I have found are designed for 1:8 multiplexing. Is it possible, and reasonable, to use this MCU with a display that only has four commons (1:4 multiplexing)? If so, would I use four consecutive commons, or every other one? Would the appearance suffer in any way? And what if the display is 1:3?
Thanks for any help. Howard Delman
