ESP32 – micropython蓝牙触控空鼠制作记录

一、ESP32-CAM固件下载和烧写

（过程请看视频：蓝牙鼠标制作记录一,micropython固件和HID库配置篇）

micropython固件：

http://www.micropython.org/download/esp32/

下载：Releases v1.17 (20210902) .bin

打开win控制台：

安装：pip install esptool

擦除：esptool –chip esp32 –port com3 erase_flash

烧写：esptool –chip esp32 –port com3 –baud 460800 write_flash -z 0x1000 esp32-20210902-v1.17.bin

查看支持模块：help(‘modules’)

touch_right = TouchPad(Pin(14)) ##鼠标左键,定义14脚为触摸脚，esp32-cam电容触摸输入IO口只有两个能用？: 12, 14

touch_left = TouchPad(Pin(12)) ##鼠标右键,定义12脚为触摸脚，因为esp32-cam的板增加了很多外设，所以就剩下12和4引脚能用触摸按键，但可以改造增加IO口

#就像我视频里用脚控制的蓝牙键盘一下，也是用esp32-cam改造增加的

3、引导文件：boot.py

<span class="token function">exec</span><span class="token punctuation">(</span><span class="token function">open</span><span class="token punctuation">(</span><span class="token string">'./mouse.py'</span><span class="token punctuation">)</span><span class="token punctuation">.</span><span class="token function">read</span><span class="token punctuation">(</span><span class="token punctuation">)</span><span class="token punctuation">,</span><span class="token function">globals</span><span class="token punctuation">(</span><span class="token punctuation">)</span><span class="token punctuation">)</span>

exec(open('./mouse.py').read(),globals())

写入后重启ESP32，用上位机蓝牙搜索添加即可正常控制了。

在此有个问题，初次连接蓝牙成功后，此时可以使用，但是一旦重启ESP32就需要在PC或上位机端删除该蓝牙设备进行重连才可以正常运行，不论是micropython还是Arduino的程序都是如此，可能是我对蓝牙连接的过程不太明白，不知道有否大佬可以解答一下，谢谢了！
