Hello, when i try to write like (an A)

00000
11110
10010
10010
10010
11110
10010
10010

it gives me

000000
111110
100110
100110
100110
111110
100110
100110

ie double the 2nd last line.

This is not the only writecombination, but others give it too. The above is with my own written display drivers, but it does the same with LCDinfo.

Can anyone suggest if some pinout is wrong? I've went trough the pcb with multimeter, can't find anything :o

Thx in advance.

Maybe some noise in the enable line.
