| 摘 要： | 在分析现有键盘电路的基础上，提出了一种全组合式键盘电路构造方法．这种键盘根据排列组合原理，用n条双向I／O口，最多可以实现2^n-1 n(2^n-1-1)个按键，数量远大于传统矩阵式键盘电路，而且可根据实际需要用其部分电路构成多种实用键盘电路。

| Abstract: | A new method for constructing keyboard circuit, namely, completely combinatorial keyboard circuit, was proposed. The new key board is composed of n bidirectional interfaces based on the principle of permutation and combination. It allows the maximum number of 2~n-1 n(2~(n-1)-1) keys to be implemented on the n bidirectional interfaces, much larger than the conventional matrix key board. Its components can also be utilized to construct key board circuits according to practical requirement. |
