HELP Nokia 6280 LCD
« on: August 06, 2017, 09:38:19 am »
I have a display of Nokia 6280.
On the Internet write that it is compatible with MC2PA8201
Hardware scrolling does not work
Void MC2PA8201_ScrollArea (uint16_t y, uint16_t pos) {
  Uint16_t bfa = 320-pos-y;
  Wr_cmd (VERTICAL_SCROLLING_DEFINITION); // 0x33
  Wr_dat (y >> 8);
  Wr_dat (y);
  Wr_dat (pos >> 8);
  Wr_dat (pos);
  Wr_dat (bfa >> 8);
  Wr_dat (bfa);
}

Void MC2PA8201_SetScrollPosition (uint16_t pos) {
  Wr_cmd (VERTICAL_SCROLLING_START_ADDRESS); // 0x37
  Wr_dat (pos >> 8);
  Wr_dat (pos);
}

When you call MC2PA8201_ScrollArea (0.320);
The screen switches to portrait mode
When you call MC2PA8201_SetScrollPosition (uint16_t pos) in the loop, nothing
Occurs
How to solve this problem?
On the Internet write that this display stands in Nokia 6270/6288/6265/6275/6282
Where can I find the description of the commands for this lcd?

Hi Rahmon,

Don't believe everything you read on the internet. In my experience I've found that these kind of displays don't bother to implement the commands that the phone will never use. Perhaps this is to save money. You may have found one of the commands that simply doesn't work on that display.
It's worse than that, it's physics Jim!

How can I find out the exact information about this display?
I have already made a device on this display.
I spent time on this device.
Do you have any connections at Nokia?
This display is very old. Why can not you find out the exact
Information on it?
I do not speak English.
Can you help me learn something?

Official information is not available. You only know what you can find out by reverse engineering.
