micropython 播放 52CM 娃娃主板 TF 卡上 mp3 文件

A、首先要确定TF中有什么MP3文件，文件在什么目录下，文件名叫什么。

B、使用“串口调试软件”得到播放的16进制代码

现在假设在TF卡上有一个目录为“系统声音”，该目录下有一个名为”欢迎访问.mp3”的文件，利用“串口调试软件”，可以得以到如下代码

0xAA, 0x08, 0x10, 0x01, 0x2F, 0xCF, 0xB5, 0xCD, 0xB3, 0x2A, 0x2F, 0xBB, 0xB6, 0xD3, 0xAD, 0x2A, 0x3F, 0x3F, 0x3F, 0x27,

A、上面的代码的设置截图

SD卡就是主板上的TF卡。系统后面的 * 是多字符通配符。？是单字符通配符，？？？通配mp3，也通配mp4。

A、micropython代码

python

import machine

uart = machine.UART(1, baudrate=9600, tx=4, rx=19)

# 发送数据

data = bytes(
    [0xAA, 0x08, 0x10, 0x01, 0x2F, 0xCF, 0xB5, 0xCD, 0xB3, 0x2A, 0x2F, 0xBB, 0xB6,
     0xD3, 0xAD, 0x2A, 0x3F, 0x3F, 0x3F, 0x27, ])

uart.write(data)

上面的 tx=4 表示 esp32 的 IO4 做为发送数据，tx19 表示 IO19 接收数据，语音识别时，语音芯片向 ESP32 发数据。 uart.write() 发数据，uart.read() 读数据。
