Hello,
I use a ili9341 + xpt2046
I use the ili9341 on 4-line serial interface II mode ( miso + mosi + sck + dc + cs )
and the xpt2046 on spi with only ( miso + mosi + cs )

The LCD work great ( I just need to select a invalid gpio ( 0 ) in menuconfig for the reset and de backlight gpio )
but the tactile doesn't work.
I think it's because the driver of the xpt2046 need to use the IRQ gpio but on my project I don't use it ( it work fine with other driver and other GUI lib.

为什么我git下来你这代码，然后把path设置好了，编译的时候出现如下错误：
