Re: IOT-Solution examples on ESP-wrover-kit V3
Customers can choose which screen they want to use. The iot-solution does not currently provide a 7-inch screen driver. Instead, it provides a driver template that can be implemented by itself.
Of course, larger screens require higher transfer rates.

Thanks a lot very useful information.
Got it working on the V4 wrover kit with proper Config settings.
There is no need to patch the code and no need to comment out the Touch drivers.
Just disable Touch in menuconfig as well as set the set the backlight active level to low.
All lvgl sample work with these settings.
See below for working wrover-kit board settings. Screen driver is ILI9314

Re: IOT-Solution examples on ESP-wrover-kit V3
@Alen59 To the best of my knowledge no additional resistors are needed. Is the latest version of esp-iot-solution being used and was the menuconfig option "Select Backlight Active Level" set to "Backlight Level Low"?
Re: IOT-Solution examples on ESP-wrover-kit V3
it started working buy switching back light low and then switch back to high.
but now i have problem with touch calibration, get calibration error and i can't pass this screen (however if i touch the points it moves to next so i believe touch part is working), i commented out touch calibration and it goes to main screen in temperature control project but touch doesn't work
