本程序实现应用软件通过并口模拟I2C通讯。

使用前将porttalk.sys复制到 System32\Drivers目录下，

再将porttalk.reg导入注册表。

将其它四个代码文件导入VC工程，主要调用 CParallelToI2C类中的函数。

相信大家可以看明白这个类的函数的作用。

另：

1. 本程序中I2C时钟周期默认为2ms，可以适当调整。

2. 电于电路不同，使用并口引脚不同，可以对类进行适当修改。-Applications of this program through the parallel port I2C communications simulation. Before use porttalk.sys copy System32 \ Drivers directory, and then import the registry porttalk.reg. The other four code file into VC projects, the main class to call a function CParallelToI2C. I believe we can see to understand the function of this type of role. Other: 1. The process by default I2C clock cycle 2ms, can be appropriately adjusted. 2. Electricity in the circuit is different from the use of parallel port pins are different categories can be amended as appropriate.
