Title: Interfacing Newheaven st7789s driver 3.5inch Lcd with iMx6Q SabreAutomotiveBoard
Post by: nandishsg on January 13, 2017, 01:36:01 AM
Hi All,

I want to interfacing the st7789s 3.5 inch lcd with iMx6q Sabre Automotive Board with parallel RGB565, My board have parallel interface so for that first i would need to initialize the LCD,So
I am Facing the problem with interfacing the st7789s driver 3.5inch lcd with iMx6q Sabre Automotive Board, My doubt is
(1) Where to connect the IM3 it is not mentioned in the Datasheet.

I tried the initialization of lcd with example code from Newheaven Display(http://www.newhavendisplay.com/app_notes/2-4TFT_ST7789.txt) but its not working to me,
I assume that IM3 is connected to LOW(Ground) internally then i tried the initialization of LCD with following mode select (a) [IM3:0] =0000
(b)[IM3:0] =0101  (c) [IM3:0] =0110 then also its not working to me, Then

I assume that IM3 is connected to HIGH(VDD) internally then i tried the initialization of LCD with following mode select (a) [IM3:0] =1001 it is also not working to me, 
can you any one suggest me how to initialization of this LCD and If Any more input is need from my side please let me know,

Thanks In Advance
