TFTs / NHD-4.3-480800EF-CTXP#-T - HX8369 continious memory write problem
« on: September 04, 2014, 02:27:24 AM »
Hello!

I am using the above mentioned display in 16-bit RGB565 mode. When writing data as single pixels (commands 0x2A and 0x2B with same start/end adress, followed by command 0x2C with a single data write afterwards) everything works fine, but a frame update is slow (12 writes for one pixel).
To speed this up I set a window via the 0x2A/0x2B commands, followed by command 0x2C with multiple data writes afterwards. This leads to a black display panel and no following single pixel write changes anything.

Is there a known problem with this setup or is there another command/setting needed to get this to work? Maybe I have overlooked something in the datasheet controller.

Many tanks in advance.

Regards,
Henning
