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. Register: The ADC has two data registers:AdclAndAdchThree control registers:Adccon1,Adccon2,Adccon3To configure the ADC and return the conversion result. [1] configure the apcfg register When ADC is used, the port 0 pin must be configuredADC analog input. To configure a port 0 pin as an ADC input,Apcfg registerMust be set to 1. The default value of this register is 0, and port 0 i

The size of the neighbor table of the master node is 24, which means that the master node can have up to 24 subnodes (enddevice or router ). In the JZA_vStackEvent event on the master node, you can set the following parameter when the network is

Talking about the blue ocean strategy of Iot Security 0 × 00 Preface In the past two years, the mobile phone market has shrunk, and global chip manufacturers are no longer able to maintain their competitiveness in the mobile phone field. Iot is the next blue ocean after mobile phones. Therefore, how to implement Iot security is worth thinking of information security workers. Iot is an emerging industry. It is very important to know the current industrial technical standards and the degree of app

1 Introduction With the continuous development of computer technology, the integration of computer science and other disciplines is becoming more and more close. The integration of computer science and the various disciplines of power system has promoted the development of China's smart grid business. However, as most of the substation is located in the field area, very susceptible to the surrounding environment, weather and other effects, substation equipment failure rate is also increasing, an
