注意
1打开开发板步骤 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 链接https://pan.baidu.com/s/1p3r3EglmYc1qoOAypOBltA?pwdb4mz 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
1lcd_init初始化
from machine import LCD
from machine import Pin
lcd LCD() #创建lcd对象
lcd.lcd_init(type3,width480,hight854) #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 (

2 LCD函数及问题
在命令行中查看LCD类并未发现提供 lcd_show_jpg 函数官方文档却提供了这个函数可能是使用的固件未包含官方的固件我都下载测试过都没有这个函数有思路的朋友可以提供一下
其他函数均可使用有需要的朋友自行尝试 注意 1py测试文件不要以main.py命名开发板启动会自动运行main文件 2不要重复初始化操作会报错
