1.官方文档快速上手,安装驱动,下载QPYcom
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

(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
python
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
python
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
python
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

gpio2 = Pin(Pin.GPIO8, Pin.OUT, Pin.PULL_PU, 1)
lcd.lcd_clear(0xffff) #刷新屏幕为白色
(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
