LVGL example with lcd 5.5 inch (RK055HDMIPI4M) on evkmimxrt595

[nghi2112]

Hello,

I just bought the new lcd 5.5 inch (RK055HDMIPI4M).

I am playing with some LVGL examples as the picture

We configured displayport.h as below for my LCD.

#ifndef DEMO_PANEL
#define DEMO_PANEL DEMO_PANEL_RK055AHD091
#endif

Here is picture of evk and lcd

My LCD could not display anything with LVGL examples. Please give me some advice.

Thank you for any help,

Nghi

Hello,

Make sure you build and erase and burned the rt, also is possible that the lcd is damage, which error appears in serial console.

Dear  Bio_TICFSL,

Thanks for your reply.

I would like to inform you that there are not issue related hardware of LCD and flashing, it work well with below lcdif examples such as lcdif_cursor_argb and lcdif_rgb565.

There are no display on all lvgl examples. Would you like confirm that I only do below configure for LCD RK055HDMIPI4M. What else do I do?

#define DEMO_PANEL DEMO_PANEL_RK055AHD091

From now, I don't see any error logs in console. I will try to enable some log level of LVGL and feedback you soon.

Best regards,

Nghi.

Dear  Bio,

I bring up lvgl example successfully. I was wrong at configure target of LCD. It is RK055MHD091A0.  

#define DEMO_PANEL_RK055MHD091 4 /* NXP "RK055MHD091A0-CTG MIPI Rectangular Display  */

The web link made me confuse. I checked its datasheet and I figure out it is RK055MHD091A0-CTG

Thanks for your help.

Best regards,
