开漏输出即漏极开路输出。这种输出方式指场效应管漏极开路输出。需要接上拉电阻才能输出1。漏极经上拉电阻接到电源，栅极输出0时，场效应管截止（阻抗无线大），电压被分到场效应管上，此时输出为1。当栅极输出1时，场效应管导通，输出端口相当于接地，此时输出0。开漏输出高电平时是由外接电源输出 … See more 输入信号经过施密特触发器接入输入数据存储器。当无信号输入时，电压不确定。因为浮空输入既高阻输入，可以认为输入端口阻抗无穷大，这样可以检测到微弱的信号。（相当于电压表测电 … See more 浮空输入在外界没有输入时状态不确定，可能对电路造成干扰。为了使得电路更加稳定，不出现没有输入时端口的输入数据被干扰 （比如手碰一下电压 … See more 推挽输出既可以输出1，又可以输出0。但是无法调节输出电压，因为输出高低电平均为三极管输入端电压，此电压在由芯片内部供电，无法改变。推 … See more WebOct 14, 2024 · GPIO, General Purpose Input Output is a set of pins in the microcontroller, which functions by passing data into and out of the board.
