-- LCD接法示例, 以Air105开发板的HSPI为例
LCD管脚       Air105管脚
GND          GND
VCC          3.3V
SCL          (PC15/SPI0_SCK)
SDA          (PC13/SPI0_MOSI)
RES          (PC12)
DC           (PE8)
CS           (PC14)
BL           (PE9)


提示:
1. 只使用SPI的时钟线(SCK)和数据输出线(MOSI), 其他均为GPIO脚
2. 数据输入(MISO)和片选(CS), 虽然是SPI, 但已复用为GPIO, 并非固定,是可以自由修改成其他脚
