GUI Guider v1.8.0 not displaying on ST7789 240*240 LCD Display for the IMX93 board

[mohamed_gaseen]

Hi,

I'm currently working on the i.MX93 board with ST7789 240 * 240 LCD display attached.

My query is that I'm using the GUI Guider library version v1.8.0, Here I'm creating the button counter interface with the configuration which I have attached below ButtonCounter.png for your reference.

And the file gui_guider also got generated successfully and the same binary running in the Remote desktop successfully. I'll share the Working-RDP-ButtonCount.png below for your reference.

But while running it on my ST7789 240 * 240 display the button counter Image is not displaying on the LED. There's no issue with the display as we are running other graphical interfaces on the same display.

Please let me know Is there any configuration I need to change for my display. Please help me to sort out this issue.

Thanks in Advance.

Hi

Did you test it when you disable the RDP?

Best Regards

Thanks for your reply,

Yeah we've disabled the weston through the remote desktop and we ran it through the frame buffer fbdev. The below command is for your reference.

weston --tty=1 --backend=fbdev-backend.so --device=/dev/fb0 &

The gui-guider demo is running on our screen but the image color is not proper. It is displaying a glitch on the screen.

The below attached image files are for your reference.

But we tested the cairo graphics to draw a font and a line on the st7789 LCD screen. there the screen color is working properly.

Please verify and let me know whether I need to change anything in the weston.ini file.

Please find the weston.log while running the fbdev below
