该程序用单片机来控制无线收发模块nrf905,实现数据的无线传输-the procedures used to control the microcontroller wireless transceiver module nrf905, wireless data transmission

提供I2C总线初始化、工作时的启始位、结束位、提供I2C总线的时钟信号，并返回在时钟电平为高期间 SDA信号线上状态。本函数可用于数据发送，也可用于数据接收-provide I2C bus initialization, the Start-end, provide the I2C bus clock signal, the clock and return to the high-level signal line during the SDA state. This function can be used to transmit data, can also be used for data reception

这个是用串口下载文件到交界处单片机的代码，而且可以用单片机接收数据用于显示，我们自己使用的工具的-serial download files to the junction of microcontroller code, and SCM can be used for receiving data, we use the tools
