==================================

You can use BOTH LCD and TOUCH

1) Enable overlays for spi and cs1

sudo nano /boot/armbianEnv.txt
add the following to the bottom

overlays=spi-spidev spi-add-cs1 
param_spidev_spi_bus=0 
param_spidev_spi_cs=1
2) Reboot your device

==================================
https://github.com/notro/fbtft/blob/master/fbtft_device.c
找到驱动对于名字fb_ili9341
LCD

1) Load fbtft and fbtft_device on boot

sudo nano /etc/modules-load.d/fbtft.conf 
fbtft
fbtft_device
2) Load fbtft_device options

nano /etc/modprobe.d/fbtft.conf 
options fbtft_device rotate=90 name=piscreen speed=16000000 gpios=reset:2,dc:71 txbuflen=32768 fps=25
3) Since there is no GUI in mainline, lets enable the console to be displayed to LCD instead

# ll /dev/spidev*
crw------- 1 root root 153, 0 Dec  6 18:16 /dev/spidev0.1

常用的模块参数有:
gpios用于指定reset,  dc, led等具体使用哪个io口
mode用于指定spi使用哪种时序
busnum用于指定使用第几个spi控制器
rotate用于指定翻转角度
name用于指定设备名
