as an Internet of things professional students, feel not to learn these things connected to the knowledge of the Internet can not afford their own, well, learning to start!!! The CC2530 has 21 digital input/output pins, namely p01-p07, P10-P17, P20-P24. In particular, it is important to note that the input and output of the CC2530 pin is different from the 51 single chip microcomputer, look at the comparison of the picture.Well, this has a basic understanding of our own
Keygen first to choose:Why?Before said CC2530 is to support ZigBee protocol wireless chip, in fact, it is this hardware has a support ZigBee protocol Radio Road, not only the circuit, but also a CPU circuit, it is 8051cpu. Then all these circuits are packaged together, called cc2530 chips.Then select GetID, copy the license number below, and copy the key from the back to the corresponding place.Create a pro

RPM: Zigbee/z-stack CC2530 Introduction to Configuration for low-power operationHttp://bbs.elecfans.com/jishu_914377_1_1.html(Source: China Electronic Technology Forum)Device support low-power operation is a major feature of ZigBee network, this feature with the help of CC2530 chip can be well reflected. The CC2530 chip has five modes of operation, namely active mode, idle mode, PM1, PM2, and PM3. The activ
Research on Controllable networking methods based on ZigBee Wireless Networks (1)
ZigBee wireless network application nodes mostly use self-networking to access the network, which may cause excessive consumption of some nodes in the network. In this case, a controllable networking mode is proposed. By selecting and controlling the parent node of a node to access the network, the topology and Node Distribut

1. Experiment Introduction
I have been learning ZigBee for almost a year. I have been learning the protocol stack for some time. This semester, because of the computer network course, therefore, I had a deeper understanding of the architecture of the ZigBee protocol stack, a deeper understanding of the operating
ZigBee technology is a wireless communication technology applied to various electronic devices at low transmission rates within a short distance. ZigBee technology has the following features: low power consumption, low cost, low rate, close range, short latency, high capacity, high security, and license-free frequency band. There are three types of devices in a ZigBee

ZigBee is a short-range wireless communication technology based on 802.15.4, featuring low power consumption, low transmission rate, and simple architecture. Its application in the field of automatic control is attracting more and more attention in the industry. Industrial Automation is mainly used in power supply, water conservancy, medical care, and other industries. In the future, it will be more like

At a minimum, the function should be called once in each while cycleIf the network information is very heavy, especially at the receiving end, the function should be called more. Ideally, when you receive a pa

Recently, when the ZigBee protocol was simulated in NS2. after the energy model was added, it was found that all nodes were green, and the changes in node color in the program were ineffective, you cannot add tags to a node. After carefully observing the source code, we found that the following two lines of the void mac802_15_4mac.cc line 919th: Recv (packet * P, Handler * h) function are in the p802_15_4mac.cc file:

The PIN mapping scheme of the timer 1 is a standby 2 scheme: P07 corresponds to Channel 3, p06-Channel 4, p12-Channel 0, p11-Channel 1, p10-channel 2~output comparison mode for timer 1: In output comparison mode, channel-dependent IO is set to output mode. (What is the output comparison mode, operating mechanism) after the timer starts, the content of the counter is compared with the content T1CCNH:T1CCNL in the channel comparison register. If the two contents (values) are equal, the output pin
informationThere must be some advantages to adding this macro definition. But the problem also comes, assuming that the terminal wants to add another network of coordinators, both Panid and channels are the same.No matter how many times you reboot, the new coordinator is not added. What should we do then?As a matter of fact ti takes this into account, here is the official noteApplication wants to delete the stored NV information It just needs to set the Zcd_nv_startup_option as explained below
