So how does a PS/2 keyboard interface work?
推荐理由
There's a good video on how PS/2 works here
说明
这是2021年由Ben Eater发布的一部教程,主题归在Electronics & circuit design。它讲的是keyboard protocols这一支里的具体问题,而不是把整个领域扫一遍。适合已经能看懂基本术语、想继续往下走的人。内容上可以概括成:Ben Eater explains how the PS/2 keyboard interface works, covering its clocked serial protocol and scancodes. He builds up the hardware-level understanding needed to read keypresses.这些读者给出的理由,核心是:HN commenters point to it as the clearest explanation of the PS/2 protocol, usually when keyboard interfaces come up.讲法不绑某一条新闻,过几年仍然可以当材料看。从2021年到2021年,有1位不同的读者在1个不同月份把它推荐出来,其中明确叫别人去看的有0次。适合打开电脑跟着做的人。如果只听不练,这集的价值会少一半。如果已经会了基本定义,就把注意力放在它怎么把keyboard protocols变成能跟着复述的例子。
