TFTs / NHD-2.4-240320CF-CSXN#-F-- Regarding its manufacturing ID read
« 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
