Python的TPYBoard驱动LCD5110脚本怎么写

这篇文章主要介绍"Python的TPYBoard驱动LCD5110脚本怎么写"的相关知识，小编通过实际案例向大家展示操作过程，操作方法简单快捷，实用性强，希望这篇"Python的TPYBoard驱动LCD5110脚本怎么写"文章能帮助大家解决问题。

MicroPython的TPYBoard驱动LCD5110，

先看一下LCD5110针脚含义吧（注意：LCD5110的针脚有些不一样的）

TPYBoard的针脚与5110的针脚对应关系如下：

TPYBoard LCD5110 memo
----------------------------
# any Pin => RST Reset pin (0=reset, 1=normal)
# any Pin => CE Chip Enable (0=listen for input, 1=ignore input)
# any Pin => DC Data/Command (0=commands, 1=data)
# MOSI => DIN data flow (Master out, Slave in)
# SCK => CLK SPI clock
# 3V3 or any Pin => VCC 3.3V logic voltage (0=off, 1=on)
# any Pin => LIGHT Light (0=on, 1=off)

# GND => GND

还是看不明白的话，直接上针脚编号吧

TPYBoard LCD5110 memo
----------------------------
Y10 => RST Reset pin (0=reset, 1=normal)
Y11 => CE Chip Enable (0=listen for input, 1=ignore input)
Y9 => DC Data/Command (0=commands, 1=data)
X8 => DIN data flow (Master out, Slave in)
X6 => CLK SPI clock
VCC
Y12 => LIGHT Light (0=on, 1=off)

GND

接线ok后，可运行main.py了。

main.py源代码：

import pybimport upcd8544from machine 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 = upcd8544.PCD8544(SPI, RST, CE, DC, LIGHT)        lcd_5110.lcd_write_string('Hello Python!',0,0)    lcd_5110.lcd_write_string('Micropython',6,1)    lcd_5110.lcd_write_string('TPYBoard',12,2)    lcd_5110.lcd_write_string('v102',60,3)    lcd_5110.lcd_write_string('This is a test of LCD5110',0,4)      if __name__ == '__main__':main()
