Hello.

I have made my drivers for the SED1330F and play with text and/or images.

The problem I am facing now is when I am scrolling the screen as the manul sais, that is, seven times with the HDOT SCR command, each time increasing a pixel, and then increase the SAD.

This is what is happening.
(assuming that the display moves to the right)

When I increase the HDOT SCR parameter, the display indeed moves one dot to the direction desired but I see empty space in the dots that are supposed to be filled with the new dots of the image. This empty space is filled only after the SAD is increased.

Any ideas? Is this what is supposed to happen or maybe there is something wrong with my code?

Thanks a lot for you help.

Also, can anyone suggest a nice project for my 256x128 LCD?

I made an analog clock but I would like to have something nicer.

I thought to hook an accelerometer there and made a "gravity simulator" with dots but it is just too difficult.

Any ideas?

Thanks.

I did something similar with a SED1335, maybe it belongs to yours?

As i remember, the rows also got shifted wrong in some case of code...
