Hi i am interfacing a 4.3 inch TFT with LPC1768 ,the controller in the display is SSD1963
it is basically a parallel 8 bit interface but the problem is even though the interface is of 8 bit in the SSD_init() function if i am sending a command to say it is 8 bit interface my display is not working properly but if i configure it as 9 bit interface it is working for some of the GUI in emwin but for some GUI's the colors are not displaying as normal

thanks and regards
Akshay H V

Hi Akshay,

I just responded to your other thread (http://www.lpcware.com/content/forum/can-we-configure-emwin-16-bit-data-transfer-our-8-bit-data-lines). In the future please try avoid opening multiply threads on the same subject.

By the looks of your code, the low-level routines are not according to spec, and the 18bpp mode you selected in the init functions is not supported by the emWin driver. If you fix those two issues, you just might be lucky and have a working LCD.

Regards,
Wouter
