Post by: darshana somarajan on October 04, 2017, 06:35:36 AM
Sir,
As I'm using Omapl138 LIDD interface to communicate with the Newhaven display, On giving command 0x0004 manufacture ID is not received.
Please do help me in finding out where I have gone wrong.

TFT_24_7789_Write_Command(0x0004);//Read device ID command

   n=LCDC->U32_LIDD_CS0_DATA;     // Dummy read
   n=LCDC->U32_LIDD_CS0_DATA;    //parameter 2 read
   n1=LCDC->U32_LIDD_CS0_DATA ; //parameter 3 read
   n2=LCDC->U32_LIDD_CS0_DATA ;// parameter 4 read

I'm sorry you are having trouble with this display.
Do you have a schematic for how you are connected to the display?
