The tree-based routing mechanism includes configuring a tree-based address and a tree-based address route. When the Coordinator establishes a new network, it will allocate the network address 0 and the network depth d = 0 to itself. The network depth indicates the minimum number of hops transmitted from one transmission frame to the ZigBee coordinator in a parent-child relationship network. If "node A" is added to the network and connected to the coo

Serialapp-ZigBee serial port application instance this example application Z-stack version ZStack-1.4.3-1.2.1 The serial application of serialapp in Z-stack is used to connect two cc2430eb boards to the computer through serial port, and data is transmitted to each other. The working process is: The cc2430 antenna receives data (OTA data), triggers sys_event_msg in serialapp_task, judges the small event af_incoming_msg_cmd in sys_event_msg, and CALLS s

flashes at intervals of 1 s (the system resets every 1 s ). Iii. Conclusion This section describes the principle and usage of the watchdog timing circuit. In practical application, if high reliability is required, the watchdog can be applied to the system. When the system is shut down for some reason (the dog cannot be fed), the dog that is not fed will bark: "Master, there is an exception, there is an exception !" For a wireless sensor network, the power consumption during operation is a cruci

conversion is completed without interruption. Each time a sequence is converted, the ADC generates a DMA trigger.

In my opinion, the algorithm and the data structure are like the methodology and epistemology in philosophy, the former clarifies the idea of solving a problem, and the latter provides the object of solving the problem.The term "algorithm" d
