Topic: LCD DV-24200-S1FBLY (KS0066 chip) (Read 1 time) previous topic - next topic


I have a bunch of these Data Vision DV-24200-S1FBLY LCD modules. They are 24x2 displays with a 14-pin interface. The information I've seen indicates that the KS0066 chip used on them is HD44780 compatible. Links to some data:

Product at Data Vision Website


I also have some 20x4 displays from a different manufacturer that I have been using successfully in 4-bit mode with the LiquidCrystal library. The pinout for both of the displays is the same.

When I plug in the DV-24200, all I get is garbled junk.

I have been over the connections several times to make sure the right pins are connected to the right places, and all seems in order.

Any suggestions from the hive mind?
