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
