这段代码是使用 SN8P2501B 微控制器来实现对 HGL12A 的驱动程序。代码中定义了一个 ChargeType 结构体,包含了用于充电时间的变量。接下来定义了一些宏,用于控制充电引脚的高低电平状态。在 IntIn() 中断函数中,根据 u8WihtchIOCharge 的值来控制充电引脚的状态和切换。在 StartOneTImeSample() 函数中,首先配置充电引脚的模式和初始状态,然后通过延时和定时器来进行充电时间的测量,并将结果存储在 u16ChargeTimeIo 和 u16ChargeTimeHumi 变量中。
请注意,这段代码仅提供了部分片段,并且缺少一些关键的信息,如函数定义、相关引脚配置等。如果你需要完整的驱动程序,请提供更完整的代码或详细的需求描述,以便我能够更好地帮助你。
