OneWire requires a single 4.7K pullup resistor, connected between the pin and your power supply. When using very long wires, or with counterfeit DS18B20 chips and 3.3V power, a resistor in the 1K to 2.7K range may be required. Then just connect each 1-wire device to the pin and ground...
使用后者下载的库文件在Arduino项目文件夹的Libraries文件夹里。在OneWire库中定义了一个OneWire类,下面我将带你从类定义、构造函数、reset()、write_bit()、read_bit()、write()、read()、select()、skip()等各类函数快速了解它。 1、下载OneWire库文件 图1 使用库管理器下载Onewire库文件 如图1所示,点击“...
-OneWire库是针对单总线推出的扩展库,了解并掌握其使用方法对于Arduino的学习非常重要。 单总线(One-Wire)是Dallas公司的一项特有的总线技术,它采用单根信号线实现数据的双向传输,具有节省I/O口资源、结构简单、便于扩展和维护等优点。One-Wire适用于单个主机的系统,能够控制一个或多个从机设备。
//用OneWire建立一个目标myWire,对应一个特定引脚 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 isolate wiring problems. You...
当你在 Arduino IDE 中尝试编译代码时,有时会遇到错误消息“包括<OneWire.h>:Arduino 没有这样的文件或目录”。这意味着编译器找不到要包括的库文件 OneWire.h。 原因 这个错误通常发生在以下情况: OneWire 库没有正确安装。 OneWire 库的路径没有正确配置。
