Or grasps in the equipment in the modern portable smart instrument, Chinese man-machine contact surface becomes one profession standard in fact. Can demonstrate that the Chinese character the graph lattice liquid crystal and may input digital the small keyboard to become the intelligent equipment essential constituent. ... -
Based on MSP430 smoke eye optimization design
Tuesday, May 26th, 2009 at 20:52 | No commentsCategories: SCMShort Content: Introduction The traditional smoke eye generally by the smog sensor and the smog survey chip constitution, the survey chip receive sensor signal and carries on processing, thus judges whether to have the fire to occur. This kind of smog detector structure is simple, the cost is low, but has the rate of false alarm to be high and environment adaptiveness bad shortcoming. In order to solve this problem, the monolithic integrated circuit is inserted to the alarm apparatus, distinguishes the ... -
Based on Lonworks main line’s embedded intelligent node design
Tuesday, May 26th, 2009 at 19:19 | No commentsCategories: SCMShort Content: 1 Foreword The LonWorks field bus is the partial operation network which American Echelon Corporation promotes, it has unified, open, the interoperability and the support many kinds of correspondence medium and so on fine performance, is now one of most popular field buses. But because LonWorks control node core neuron chip (Neuron Chip) application handling ability is relatively weak, thus often uses regarding the complex application main from the processor structure, the main processor completes the user the application function, ... -
With realizes - 51RD based on the MSP430 track circuit online reflectoscope reflector design the Chinese electronic net
Tuesday, May 26th, 2009 at 18:25 | No commentsCategories: SCMShort Content: Along with the train vehicle speed's unceasing enhancement, is also getting higher and higher to the train track's request. Original has the insulation track circuit to be unable to satisfy the railway transportation enterprise need to develop, thus the world each advanced industrial nation starts to develop non-insulation track circuit [1]. And, develops the successful UM71 non-insulation track circuit application by French CSEE Corporation to be most widespread. This system introduced our country in the late-1980s, this kind of non-insulation ... -
Based on MSP430 and PROFIBUS monitor sub-station design
Wednesday, December 10th, 2008 at 05:29 | No commentsCategories: Communication NetworksShort Content: Abstract: Realized using MSP430F149 and the SPC3 chip had the PROFIBUS-DP main line's speed reducer condition to monitor the sub-station, could monitor the vibration, the axis to be warm, the rotational speed, electrical machinery's voltage and the electric current, simultaneously had the LCD demonstration, the parameter memory function. Has realized speed reducer's online intelligent monitoring. Key word: PROFIBUS; MSP430; SPC3 Introduction In professions and so on electric power, steel and iron, petroleum, chemical industry, has the ... -
Based on MSP430 pronunciation and audio frequency compression/solution compress technique
Friday, November 28th, 2008 at 00:35 | No commentsCategories: SCMShort Content: Introduction Uses micro controller (MCU) to implement the pronunciation recorder to be quite simple. Many MCU uses the integrated modulus (A/D) switch. The loudspeaker will catch the sound provides to the amplifier, then presents again gives a/D switch's analog input. May the sound which records save, in dodges saves or memories and so on RAM, presses down the button to be able to trigger the sound which MCU broadcasts records, its principle is the data which saves provides first ... -
Micro controller management power source sorting and control
Monday, November 17th, 2008 at 18:12 | No commentsCategories: Power SupplyTags: MSP430Short Content: Along with the double voltage architecture and the multi-processor board's rapid popularization, possibly needs several processor voltage skeleton line including the simple application. Because each processor has own Canada and the power failure request, power source skeleton line sorting and the control turn a complex duty. The power source designers face the challenge is needs to consider that each processor fixed time with the voltage request, and buys in these requests in the overall system, guaranteed that designs finally satisfies ... -
Realize - en.51rd.net based on the MSP430F449 data storage and the USB serial communication
Sunday, November 2nd, 2008 at 03:49 | No commentsCategories: StorageShort Content: Abstract: In the data acquisition equipment as well as has in the related function instrumental design, the data memory and the transmission are a very important link, this article in the success practice foundation, introduced that after micro controller MSP430F449 realizes the data gathering data storage and with the superior machine data communication related content. In the article has given the practical hardware circuit and the partial software code, explained some links which in detail needs to pay attention in ... -
Between MSP430 multi-processor’s mailing address and agreement
Tuesday, October 28th, 2008 at 05:23 | No commentsCategories: Communication NetworksShort Content: Abstract: The MSP430 function was already formidable, its internal peripheral device is rich, suits the numerous situation uses; But in the large-scale complex situation or the timely request high situation, uses processor processing all services, always appears some insufficiencies. The introduction multi-processor cooperation work's pattern, may enhance system's timeliness, the reliability and the serviceability; Using the MSP430 inherent characteristic, chooses the UART pattern, uses .ModBus the communication protocol, may carry on between the different processor's data exchange.Key word: Multi-processor UART ... -
MSP430 system application structural design and shaping
Sunday, October 26th, 2008 at 21:20 | No commentsCategories: SCMShort Content: 1 MSP430 synopsis MSP430 is 16 monolithic integrated circuit serial products which TI Corporation promotes, has the unique superiority in battery power supply's low power loss application.
