Thx, amazing work!

nice tutorial👏🏻👏🏻🤩

Very nice video, THX.

Thank you so much

if I wanted to use a bezel/shell, resizing the screen would be possible?

Thx!

FYI I have a recent version of the board and the clock that comes on after using the EspTouch app now seems to configure its time zone automatically. At first it showed 12:34 (which was not local time in China, just the 1-2-3-4 digits) and then it switched over to my local time. Also the EspTouch app reported an error and said no device was found, but the board still picked up the wi-fi network credentials and configured itself successfully after a few tries. The process doesn't seem exactly reliable but with a little patience I was able to get it to work eventually.

Thank you for sharing your experience!

What about of the brighteness of the display? It is readable outdoor under a sunshield/suncover? Maybe the brightness can be regulated/pumped up?

@usefulelectronics

The brightness can be controlled by driving the backlight pin with PWM signal. I can add this feature in the future. Stay tuned:)

You need to make some tweaks to make it work with Arduino IDE

Nice presentation, but why you tell we can show 256 colors (video at 2:17) ? 8bit is the communications interface, not the color depth. Indeed, in your example you set the colors as 24bit RGB value.

ESP32 has pin signal multiplexing capability. You can change the I2C pins to the available ones.

Can you do a video with LGVL Studio using GPIO pins with buttons? Turn something on/off.

I will be having more tutorials related to LVGL with T-HMI board. Stay tuned for that !

Very good and helpful video. Just one thing I do not understand about displaying a simple image using lvgl: Every image must have a .png and .c component. Lets say I download a .png format image from google. How can I create the .c part for that image? For example, in your project you have ue_logo.c and ue_logo.png. How did you create ue_logo.c?

Where are you from ?

How are you supposed to mount the display to anything if it doesn't have 4 x mounting holes at each corner? I'll never understand why display manufacturers don't think about this...

Well, the library needs a good RAM footprint and high speed to handle the display

Compile won't work because of people that love werror. Component library won't compile. The commented options in cmakelist don't work.
