Dalomus Posted June 8, 2019 Report Share Posted June 8, 2019 (edited) Hi all I use a Nucleo-F767ZI board and a 4.3" touch display (ER-TFTM043-3) with RA8875 display controller (connected via SPI). So the initialization is working but the colors are wrong (black and red are yellow). Can anyone help me with this problem? Thanks in advance Kind regards Edited June 8, 2019 by Dalomus Link to comment Share on other sites More sharing options...
Joel Bodenmann Posted June 8, 2019 Report Share Posted June 8, 2019 This is most likely a mismatch of the color formats. Check the color format configuration of your GDISP driver (eg. /drivers/gdisp/RA8875/gdisp_lld_conf.h). It defaults to RGB565. You have to ensure that the display controller on the other end is using the same color format as specified in the GDISP driver configuration.

Dalomus Posted June 8, 2019 Author Report Share Posted June 8, 2019 Hi Joel Thanks for your answer. I checked this more than one time and it's set to RGB565 what i think actually is the color format of the controller. Or am I wrong? Link to comment Share on other sites More sharing options...
inmarket Posted June 25, 2019 Report Share Posted June 25, 2019 If both black and red are turning out yellow then the problem is more likely in the controller initialization sequence for your panel. If you have any code that can initialize the panel copy that into the gdisp driver and see if that solves your problem. Link to comment Share on other sites More sharing options...
