串行通信和并行通信 在硬件通信里,一般有两种通信方式:串行通信(Serial Communication)和并行通信(Parallel Communication)。这两种通信方式的区别从字面理解也很简单:串行就是数据一个接一个的发送;并行就是所有数据都同时发出。 但由于并行通信在线路成本和同步困难方面的问题使其在实际应用上面远不如串口通信来得广泛。
myWire.select(addrArray) Do a ROM select. Select a device based on its address. After a reset, this is needed to choose which device you will use, and then all communication will be with that device, until another reset. Issue a 1-Wire rom select command, you do the reset first. /...

At any given time only the master will be able to initiate the communication. Since there is more than one slave in the bus, the master has to refer to each slave using a different address. When addressed only the slave with that particular address will reply back with the information whil...

The Import Library option allows you to import functionality from a library created for a specific purpose, for instance, working with Motors or I2C communication. These can be either the default libraries that come with Arduino or a library that you have created yourself. If you select the Ste...
