Hi, I have a S1D13700 (SED1335 compatible) driving a Hitachi 320x240 LCD, configured in text mode, direct addressing mode. The problem is that I write a character at 0,0 O.K but it is duplicated in the Y axis for the full height of the display! Can anybody suggest an electronic reason this might happen? My initialisation settings are. MCR = 0x30 HCS = 0x07 VCS = 0x07 CBPR = 40 TBPR = 52 L/F = 239 AP = 41 SB1SA = 0 SB1SZ = 239 Thanks |

im not an expert, but it sounds like a wiring error. Probably best if you recheck it all |

What wiring connection do you use? The LPT one! |
