We are using a LCD display needs following settings:
Ampire’s 800480S series is DE only mode. The HSYNC and VSYNC are not needed.
I consider that you need give the HSYNC and VSYNC setting to your LCD controller.
You can follow the setting.
Pixel clock : 33.26MHz = CLK frequency FCPH
Hsw + Hbp +Hfp = DE period – DE pulse width=256
Horizontal Synchronization Width (hsw) = 3
Horizontal Back Porch (hbp) = 83
Horizontal Front Porch (hfp) = 256-83-3=170
Vsw + Vbp +Vfp = DE frame blanking=45
Vertical Synchronization Width (vsw) =3
Vertical Back Porch (vbp)=12
Vertical Front Porch (vfp)=45-12-3=30
Details can be found here
Please let me know how to set those parameters on WEC2013 Colibri iMX6 module.
The LCD is displaying OK but has some flickering issues due to those settings not done properly.
