本例程用于支持Waveshare的TOF Laser Range Sensor系列IIC模式通信，使用C语言编写，采用模拟IIC通信，底层代码基于STM32 HAL库编写，移植时需要根据所使用的控制器更改us级别延时函数和引脚配置等部分代码。
This Demo is Waveshare’s TOF Laser Range Sensor series IIC mode communication. It is written in C language and uses virtual IIC communication. The underlying code is written based on the STM32 HAL library. When porting the code, it is necessary to change the us level delay function and according to the controller used. Some codes such as pin configuration.
