LVGL screen recommendation for nRFLM20DK

[ramkumarkoppu]

Hi,

I a\m looking for your recommendation on screen to use with nRFLM20DK board to experiment with LVGL display. Assuming that latest version of nRF Connect SDK has everything required to develop graphical screen and touch input.

Still waiting for response from Nordic on this.

Hi,

As said on my previous message, we can't give you any LVGL display recommendation...

Best regards,

Has Nordic team tried LVGL on nRF54LM20 MCU at all? if they dis, are there any reference example to try our end? without trying how do we know this MCU is suitable for graphical display?

Hi,

The Zephyr LVGL API doesn't require any particular hardware. So, as long as the MCU is powerful enough and has enough space it will be able to run. Of course the resource needed are determined by the wanted resolution, color depth, refresh rate, and so on. But the nRF54LM20 should already be able to handle quite a lot of screens.

I just want to point that It seems you are a bit confused about what LVGL actually is. LVGL is a graphical API that is hardware-agnostic, it does not handle any hardware directly. LVGL will send data to Zephyr display driver. And that driver will send it to the screen through SPI/I2C/.... So even the term LVGL display is not exactly correct.
