CUSTOM DE MODE LCD for IMX RT1176

[tbayram]

There is an Custom LCD that works in DE mode. Is IMX RT1170 eLCDIF driver support available? where can I find out?

Have a nice day!

hi @diego_charles , RGB interface,565 RGB.

But our custom LCD doesnt have HSYNC & VSYNC. Does NXP support RGB interface without HSYNC & VSYNC.

Hi @tbayram 

As far I know the eLCDIF and LCDIF  do not have a way to generate DOTCLK without HSYNC and VSYNC signals.

For a custom LCD, I think that you can use the FlexIO peripheral. We have an app note AN5280 Using Kinetis FlexIO to Drive a Graphical LCD  that shows the use of FlexIO but for an LCD that does use HSYNC and VSYNC based on Kinetis MCUs (Please note that the FlexIO IP from Kinetis is pretty similar to IP implementation on i.MX RT) . But FlexIO is not tied to work this way, you can customize. I mean that you could develop the desired interface for your LCD. Currently I do not have more guidelines about how this could be done. But I hope the AN could give you an idea.

Thanks a lot for your patience.

Hi @tbayram 

Many thanks for your patience. 

The eLCDIF module does provide an enable signal.

But do you know the interface mode of the display? for example dotclock, pigeon mode etc.

hi @diego_charles ,

First of all thanks for your reply. 

Yes, I referring to data enable mode.

Have a nice day.

Hi @tbayram 

Would you please provide the datasheet of the LCD to take a look at this custom DE mode? Are you referring to date enable mode? 

Many thanks
