Hey guys, I got a board from an old machine that has 5x NEC D7225G connected to 5x 6-character 14 segment LCDs, the board is damaged and has quite a lot of components missing. I was wondering if anyone would know how I could possibly hook up the D7225G to an arduino to drive a single LCD. Tried to read the datasheet but I really have no idea where I should start. Will be grateful for any form of help Thank you Photos: https://www.dropbox.com/sh/1r7yenmil3w9d3d/AAA_aZl_Bn2M3caVtNMMC_JXa?dl=0 |

The uPD7225G is a standard LCD controller/driver. The interface is a synchronouse serial 8 bit port. Thus you can control it with any MCU/CPU which has 3 ports or SCI. See more details: https://www.lcd-module.de/eng/pdf/zubehoer/upd7225.pdf /PeLuLe |
