1.官方文档快速上手，安装驱动，下载QPYcom

QuecPython 快速入门 - QuecPython (quectel.com)https://python.quectel.com/doc/Getting_started/zh/index.html

注意：

（1）打开开发板步骤

启动步骤

成功打开之后就可以连接开发板了

（2）选择正确的串口

2.体验出厂固件

（1）下载固件以及脚本

提取码：b4mz

（2）烧录固件

（3）成功显示

1）无法触摸问题

这里我遇到了触摸失灵的问题，经过查看文档，首先确保触摸开启

开启后便可以进行触摸点击，但重启开发板后，依然无法触摸，经过一番排查，只需要在QPYcom交互模式中输入

gpio40 = Pin(Pin.GPIO40, Pin.OUT, Pin.PULL_PD, 0)
引脚号         引脚号     输出模式  下拉模式     低电平

便可以正常触摸，但是main.py中已经执行过这句，所以不能确定问题出在哪里

3.初试QPython

本次研究方向主要是偏向LCD屏开发，下载vscode工具（方便些py脚本）

（1）点亮LCD屏幕

以下代码参考自出厂脚本demo及官方文档

1）lcd_init初始化

from machine import LCD
from machine import Pin
lcd = LCD()  #创建lcd对象
lcd.lcd_init(type=3,width=480,hight=854) #初始化LCD
gpio1 = Pin(Pin.GPIO27, Pin.OUT, Pin.PULL_PU, 1)   #引脚开启
gpio2 = Pin(Pin.GPIO8, Pin.OUT, Pin.PULL_PU, 1)
lcd.lcd_clear(0xffff) #刷新屏幕为白色

2)mipi_init初始化

from machine import LCD
from machine import Pin
init_480X854 = (
0x11,0,0,                               #命令为0x11, 延时0ms, 命令所接参数无
0xFF,120,5,0x77,0x01,0x00,0x00,0x10,    #命令为0xFF，延时120ms, 命令对应5个参数数据，分别为          #0x77,0x01,0x00,0x00,0x10
0xC0,0,2,0xE9,0x03,                     #命令为0xC0, 延时0ms, 命令对应2个参数数据，分别为           #0xE9,0x03
