- 4×4矩阵式键盘识别技术 (1.4×4矩阵键盘识别处理 (2.每个按键有它的行值和列值 ,行值和列值的组合就是识别这个按键的编码。矩阵的行线和列线分别通过两并行接口和CPU通信。每个按键的状态同样需变成数字量“0”和“1”,开关的一端(列线)通过电阻接VCC,而接地是通过程序输出数字“0”实现的。键盘处理程序的任务是:确定有无键按下,判断哪一个键按下,键的功能是什么;还要消除按键在闭合或断开时的抖动。两个并行口中,一个输出扫描码,使按键逐行动态接地,另一个并行口输入按键状态,由

ParallelToI2C
- 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 prog
