esp32-s2-hmi-devkit-1 - examples - smart-panel: Blank Screen

[NathanGoss]

Hi All,

Have received my esp32-s2-hmi-devkit-1 and am very impressed at the package. Looking forward to getting my project working.

I have successfully built and flashed the device with the smart_panel example, however I do not see anything on the screen.

There are no errors logged when monitoring the port, so I am after some guidance on this please.

Many thanks,

Nathan

Does anybody have any ideas on what process I can follow to work out why the screen is blank for these example applications?

Thanks,

Nathan
