Hi all,
I connected a T6963C based display (240X64) to a National COP8 microcontroller. I am writing the software but I found some problem:

- I try to inizialize the controller then I write some data to the graphic memory but I get nothing on the display
- Every command or data I write I have to wait a long long time before the status bits STA0 & STA1 go high (from 0.5 to 1 second).

I am know that the display work (I tested it with PC parallel port & PowerLCD 1.1)

I really cannot understand and I need help.
Many thanks,

Have you tried without status checking and just with a little delay in place of that ? How about the code, is the initialization ok and is the memory pointer set in correct place before trying to write ?
