术语 | keyboard encoder |
释义 | keyboard encoder 键盘编码器 An encoder that identifies each key and mode with a simple binary number. The ideal keyboard encoder would be a single chip with programmable operational parameters. Requirements for four critical functions are involved in the design approach to a keyboard encoder: keyboard scanning, key debouncing, key encoding, and indication of key data availability. 一种典型的编码电路,用简单的二进制数来标识每个按键的功用和工作方式。理想的编码 器应是一个带可编程操作参数的单一芯片。在设计键盘编码器的过程中要涉及如 下四个关键的功能要求: 键盘扫描、防止按键颤动、按键编码和键数据有效性的指示。 |
