此程序是I2C操作平台（主方式的软件平台）的底层的C子程序,如发送数据

及接收数据,应答位发送,并提供了几个直接面对器件的操作函数，它很方便的

与用户程序连接并扩展..... 这个头文件51系列机型可以通用.



XX7299.DRV

注意:函数是采用软件延时的方法产生SCL脉冲,固对高晶振频率要作

一定的修改....(本例是1us机器周期,即晶振频率要小于12MHZ)-This procedure is I2C platform (the main form of software platform) of the bottom of the C routines, such as the send data and receive data, response to digital transmission, and provide the face of several direct the operation of the device function, it is very convenient and user to connect and expand the headers ..... 51 Series models can be generic. XX7299.DRV Note: function is the use of software methods delay SCL pulse, solid crystal of high-frequency have to make some changes ... . (in this case is 1us machine cycle, that is, less than crystal frequency 12MHZ)
