/*
* @Description(CN):
* 基于Arduino_DriveBus库的SY6970充电芯片例程
* 以下是使用该款芯片需要注意的几个点：
* 1. SY6970在获取芯片电压电流的时候需要开启ADC测量功能才能正常检测到电压电流等数据
* 如果未开启则获得的是错误信息
* 2. 在使用Arduino_DriveBus库时，初始化阶段会对芯片进行一次初始化的写入数据，具体
* 初始化内容可以前往芯片文件下的XXX_Initialization_Operations[]这个数组查看
* 3. Arduino_DriveBus库使用枚举的方式寄存操作芯片的命令和值，具体的可执行命令已经在
* 芯片文件的@Description有说明
*
* @Description(EN):
* SY6970 Charging Chip Routine based on Arduino_DriveBus Library
* Here are a few points to note when using this chip:
* 1. When obtaining voltage and current data from the SY6970 chip, the ADC measurement
* function must be enabled to correctly detect the voltage, current, and other data. If not enabled,
* error messages will be obtained.
* 2. When using the Arduino_DriveBus library, the chip is initialized with data during the initialization
* phase. The specific initialization content can be viewed in the XXX_Initialization_Operations[] array in
* the chip file.
* 3. The Arduino_DriveBus library uses enumerations to register commands and values for operating
* the chip. The specific executable commands are explained in the chip file under @Description.
