程序示例：

# main.py -- put your code here!
import pyb
import lcd5110
from pyb import SPI,Pin

def main():
  SPI    = pyb.SPI(1) #DIN=>X8-MOSI/CLK=>X6-SCK
  #DIN =>SPI(1).MOSI 'X8' data flow (Master out, Slave in)
  #CLK =>SPI(1).SCK  'X6' SPI clock

  RST    = pyb.Pin('Y10')
  CE     = pyb.Pin('Y11')
  DC     = pyb.Pin('Y9')
  LIGHT  = pyb.Pin('Y12')
  lcd_5110 = lcd5110.LCD5110(SPI, RST, CE, DC, LIGHT) #设置LCD5110使用SPI1及其它功能引脚
