关于SHT15的时钟输入的编程，以上函数可以实现SCK和DATA总线的各种输入与输出状态。在SHT15的通信中还需要延时函数，设计时采用函数void DelaylIn8(U32 tt)实现软延时。这样就能完成对SHT15通信协议的模拟。-SHT15 the clock input on programming, the above function can be achieved in a variety of SCK and DATA bus input and output. In SHT15 also need to delay the communication function, designed with function void DelaylIn8 (U32 tt) to achieve the soft delay. This communication protocol can be completed SHT15 simulation.
