12 KEY1 Key
13 RST Reset
15 LCD_RS LCD instruction control, Instruction/Data Register selection
16 KEY2 Key
18 KEY3 Key
19 LCD_SI / TP_SI SPI data input of LCD/Touch Panel
21 TP_SO SPI data output of Touch Panel
22 KEY4 Key
23 LCD_SCK / TP_SCK SPI clock of LCD/Touch Panel
24 LCD_CS LCD chip selection, low active
26 TP_CS Touch Panel chip selection, low active
13==RST 15==RS
==================================
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
