-- LuaTools需要PROJECT和VERSION这两个信息
PROJECT = "ccdemo"
VERSION = "1.0.0"
log.style(1)
--[[]
运行环境：Air780EHV核心板+AirAUDIO_1000配件板
最后修改时间：2025-6-17
使用了如下IO口：
[3, "MIC+", " PIN3脚, 用于麦克风正极"],
[4, "MIC-", " PIN4脚, 用于麦克风负极"],
[5, "spk+", " PIN5脚, 用于喇叭正极"],
[6, "spk-", " PIN6脚, 用于喇叭负极"],
[20, "AudioPA_EN", " PIN20脚, 用于PA使能脚"],
3.3V
GND
执行逻辑为：
设置i2s和音频参数，读取文件qianzw.txt里面的内容，然后播放出来
