自己使用VB编写的串口通信程序，1号和2号。将两个COM口用串口线连接，就可以运行这两个程序了。实现的功能：1号程序随机发送两个数字，2号程序接收并进行计算，然后发回1号机，1号机接收并显示出来。-its own use VB prepared by the serial communication program, 1 and 2. The two COM ports with serial line connectivity, it can run on the two proceedings. The functions : 1 random procedure to send two figures, the No. 2 receiver and procedures for calculating and then sent back No. 1, No. 1 receiver and displayed.

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
