One of my dreams is to do a one-arm pullup.

我的梦想之一是单手垂挂。

This constant defines the port on which the pullup resistor is connected.

这个常量定义了上拉电阻是连接到哪个口的。

Omit resistor R3 if IC2 includes built-in pullup resistors, as do many modern microcontrollers.

如果IC2包括内置的上拉电阻，就可以忽略电阻r 3，许多现代微处理器都是这样的。

It is the responsibility of the host designer to connect external pullup resistors to those lines.

主机设计者有责任给这些连接线加上外接的上拉电阻。

I had a Pullup bar at home before, but one of my friend broke it when he tried to monkey around on it.

我有一个上拉酒吧在家过，但是我的朋友之一，他打破了它试图猴子它。
