This is a demonstration of the LVGL graphics library running on the NuttX LCD
driver with the ILI9341 display. You can find LVGL here::

This configuration uses the LVGL demonstration at `apps/examples/lvgldemo` and
can be executed by running the `lvgldemo` application.

is provided via the ESPTOOL_BINDIR variable.

depends on LCD_ILI9341
---help---
The ILI9341 and ST7789 specify that the maximum clock speed for the
SPI interface is 10MHz. However, in practice the driver chips work
fine with a higher clock rate, and using that gives a better
framerate. Select this to try using the out-of-spec clock rate.
