Don't guess - ask instead. If you don't ask you won't know. Thanks Sapieha. Jim Mike B. Does this look familiar to anyone? The seller states he can't find any data on it but claims it is a serial display.
Any help on this item or a pointer to a similar LCD that is serail would be great if you could help me out. I'm a Prop newbie! Ale Posts: 2, Mike, that display should be a x unit. In the datasheet is all the info you need to drive it, 4 bits data, M signal maybe , frame, clock and most important bias voltage it may be positive or negative From the board: - There are 5 connections form the LC to the connector but the M signal may be routed on the other side.
M signal is not at all difficult to generate - Pins 91, 90, 89 are all connected to VDD, 89 is V3 that would mean that the bias voltage is negative. Some V are then needed I did not read that the controller specifically says negative bias!.. Look here for a dual-scan LCD with the propeller with similar interface: propeller.
