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

equipment, because of this ID can be used with each other, Chint's switch can control Philips lights ...Endpoint, the name seems easy to misunderstand, think it is the serial number of the device, it is not. In this example, Z1 has key1/key2 two endpoint, doing different things separately. It corresponds to the same "application" in the 0-240 different "sub-applications", of which No. 0 endpoint is "ZDO" reserved, can not occupy. If you are familiar with TCP/IP, you may feel that the Endpoit an

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

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

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
