OneWire myWire(pin) Create the OneWire object, using a specific pin. Even though you can connect many 1 wire devices to the same pin, if you have a large number, smaller groups each on their own pin can help is
· MsTimer2 - uses the timer 2 interrupt to trigger an action every N milliseconds. · OneWire - control devices (from Dallas Semiconductor) that use the One Wire protocol. · PS2Keyboard - read characters from a PS2 keyboard. · Servo - provides software support for Servo motors on any ...

and the eighth bit determines if it's being written to or read from. The Wire library uses 7 bit addresses throughout. If you have a datasheet or sample code that uses 8 bit address, you'll want to drop the low bit (i.e. shift the value one bit to the right), yielding an addr...

Wire.requestFrom()主机向从机请求字节/数据 Description Used by the master to request bytes from a slave device. The bytes may then be retrieved with theavailable()andread()functions. As of Arduino 1.0.1, requestFrom() accepts a boolean argument changing its behavior for compatibility with certain...

如此一来,以太网的拓扑结构就成了星型;但在逻辑上,以太网仍然使用总线型拓扑和CSMA/CD(Carrier Sense Multiple Access/Collision Detection,即载波多重访问/碰撞侦测)的总线技术。以太网实现了网络上无线电系统多个节点发送信息的想法,每个节点必须获取电缆或者信道的才能传送信息,有时也叫作以太(Ether)。(这个名字...
