1. Introduction to ZigBee protocol stackProtocol is a series of communication standards, both sides of the communication need to follow this standard for normal data transmission and reception. Protocol stack is a concrete implementation of the Protocol, the popular protocol stack is a protocol and the interface between users, developers through the use of protocol stack to use this protocol, to achieve wireless data transmission.1: The

Introduction: PWM for a lot of software engineers may be familiar and unfamiliar with PWM to adjust the LED brightness For example, its essence is in every period of cutting corners, the overall performance of the LED under-voltage brightness of different effects. As you can see the seven color lantern its principle is similar, just with 3 PWM control red, green, blue three colors of the lamp output brightness, and then combined with the principle of mixing color to show the colorful effect ~Wri

I. PrefaceHello everyone, I am a college student, recently to ZigBee very interested, so I bought from the internet a fire cc2530 ZigBee Development Board, want to through this platform to share their own study and research experience, below to simple introduction of ZigBeeTwo. ZigBee definitionZigBee is a low-power LAN protocol based on the IEEE802.15.4 standard

Comparison of main ZigBee chip vendor's ZigBee solution competitiveness Comparison of main ZigBee chip vendor's ZigBee solution competitivenessAt present, there are major ZigBee chip vendors (2.4 GHz), including Ti/chipcon, Ember (ST), jennic (), Freescale, and microchip.Cur

generate a system reset signal to let the system reset. Therefore, 69 lines in the code if the comment out feed the dog, the result is the system constantly restart LED2 flashing, if the dog feed LED2 solid.ZigBee Series Articles:[ZigBee] 1, ZigBee introduction[ZigBee] 2, ZigBee development environment construction[

value of the 12-bit valid data that obtains the ADC sample is saved in value value = ADCL >> 4; ADCL Register low 2 bit invalid, because he only 12 bit valid, ADCL register low 4 bit invalid. A lot of code on the network here is the right shift two bit, that is not the value |= ((UINT) ADCH) But the value is only the ADC value, not the temperature value, need to convert, the code 18, 19 lines is to complete the conversion: (As for how to calculate I guess there should be a form

ObjectiveAt present, China vigorously promote the internet of Things is the main battlefield of ZigBee applications, the Internet of things through intelligent sensing, recognition technology and pervasive computing (I also specifically applied for a domain name PSJS.VIP), ubiquitous network fusion application, known as the second computer, the world's information industry after the development of the third wave. If you want to make a difference on th

First knowledge of ZigBee technology 1 Zigbee protocol 1. ZigBee is a short-distance, low-rate wireless data transmission protocol (IEEE 802.15.4 protocol ). Wireless network operating frequency: 868 MHz, 915 MHz, 2.4 GHz Maximum data transmission rate: 250 kbps 2. Zigbee protocol: 2.1 Adopt a layered approach and dif

First, understand the basic knowledge of ZigBee1) Three types of nodes, three roles--cc2530Coordinator Coordinator: (only one) starts from it, assigns network addresses, allows the device to join or exit, and transmits datagrams.Router Rooter: Large area network or tree network, used to find the best path, other same coordinator (cannot build network)Terminal Enddivice: Joining or exiting the network, transferring data2) network topologystar Topology (simplest, only terminal and node, ready for

Solemnly declare: The following articles are suitable for beginners of ZigBee children's shoes, the great god please skip ... 1 reasons: work has heard of ZigBee technology, just know is a wireless communication technology, specific technical details and use are not very clear. Unexpectedly, a project requires the use of ZigBee technology, which is to take
