When all the devices on the bus have "released" the communication lines, the only influence on the circuit is the pull-up resistors, which pull the lines high. 当总线上所有的设备都“释放”掉通信线时,对输出目标电路的唯一影响就是上拉电阻将输出端的电平拉高。 WikiMatrix The isolation unit...
The function of a pull-up or pull-down resistor is toconduct awayany undesired electrical chargeso that it cannot impact the input pin's state. (Pull-upresistors prevent the pin from floating by forcingthe signalto VCC when it is not being actively driven.) For this, the resistance of th...
Since pull-up resistors are so commonly needed, many MCUs, like the ATmega328 microcontroller on the Arduino platform, have internal pull-ups that can be enabled and disabled. To enable internal pull-ups on an Arduino, you can use the following line of code in your setup() function: ...
1 Introduction Pull-up resistors are very common inmicrocontrollersor any digital logic device. With a pull-up resistor, the input pin willread a high state when the button is not pressed. When the button ispressed, itconnects the input pin directly to ground. ...

A pull-up resistor on the 10K between the node and the positive 5V power is used to pull up the point of the node. I really do not understand, in order to put the potential up, directly connected to the power supply is not enough The power supply through this 10K resistor will ...
