读取

Through circularly exporting certain electrical levels on the rows of matrix keyboard, the electrical levels of the lines will be read, then the aim of scanning matrix keyboard will be realized by comparing the output and input. As the electrical level array of rotary keyboard is different when positive and negative circumvolving, the direction can be judged by comparing the electrical level of A and B phase.

本题目利用Mega16单片机以及外围电路，以C程序设计语言为基础，通过使矩阵式键盘的行端口循环输出一定的电平，接着读取列端口的电平，经过比较就可以实现对矩阵式键盘的扫描，因为旋转编码器的正反方向输出电平序列的不同，因此通过对其输出端A和B的相位进行比较即可实现对旋转编码器的方向判定。
