实际上,乐鑫信息科技所实现的IIC通信类的名字是TwoWire,然后在Wire.h文件已经为大家创建了两个全局的实例对象Wire和Wire1供大家直接使用。 2. setPins(int sda, int scl) 这个方法用来设置IIC通信使用的引脚。这个方法不是必须要调用的,如果没有调用本方法设置IIC通信引脚,那么将使用默认的21、22引脚作为IIC通信
Pin Plugs:Apin plug, otherwise known as a jumper wire is a simple wire with a single plug on the end that you can use to connect external devices to your Arduino. Each pin plug can connect to one pin on your Arduino. For example, one wire could be connected to pin 13 (which will...
CAN Bus is a small-scale networking standard, originally designed for cars and, yes, busses, but is now used for many robotics or sensor networks that need better range and addressing than I2C, and don't have the pins or computational ability to talk on Ethernet. CAN is 2 wire differenti...
Wire.setSCL(pin) Configure the pin used for clock. Possible alternate pins are shown on the pinout card. This function may be called before or after Wire.begin(). All pins used must have real pullup resistors. Use of Other I2C Ports To use the other ports, replace Wire with Wire1,...
