## Ilitek 9341 TFT + XPT2046 touch controller support
Thas adds Ilitek's 9341 LCD and XPT2046 touch controllers support over SPI. One needs to enable via 'luckfox-config'.
Certain linux kernel and buildroot packages need to be enabled. My configs can be found here: [buildroot config](config/pottendo-buildroot-config) and [kernel config](/pottendo-kernel-config).

Here some demo I wrote: [TFT screen & Touch - blending with camera stream](https://photos.google.com/photo/AF1QipO2BUhd35yjDADPHEMfYXdPDCh_vv_lHku0w498). Source can be found [here](https://github.com/pottendo/pottendo-mandel).
Note that to run the demo one needs a more recent opencv-mobule (4.10) to be compiled and used (support for direct renedering into a framebuffer using `imshow("fb", ..)`).
