Glcd problems

Hi

I am having problems using a lcd from everbouquet of the type MG1203D. Its a 122x32 pixel display which uses two sed1520 ic as control of the panel. Some of the trouble I have might be because the manufacturer has choosen to leave out some of the connections to the controller ic’s, such as read/write, which is tied to ground. However, if anybody has used the controllers or chips and has some assembler code they might be willing to share, id be very gratefull.

Best regards,

Ok… so I managed to work it out. It turned out that I had forgot to set some cs lines to output state - stupid me. Anyway, is there anyone that has an idea of where its best to do such a thing as set the ports. I fell so dirty be having them in the lcd init routine…
