ISP technology and Internet union applied research
Thursday, November 20th, 2008 at 16:45 | No commentsCategories: Communication NetworksShort Content: In the system programming technology (In-System Programming, is called the ISP technology) is one kind which the Lattice semiconductor company first proposed causes the product in the design, process of manufacture each link, even after selling to the end-user, has to its component, the circuit wafer either the entire electronic system's logic and the function momentarily carries on the configuration or the reorganization ability newest technology. The ISP technology eliminated traditional technology certain limits and connection disease, is advantageous ... -
Based on FPGA liquid crystal display controller design
Wednesday, November 19th, 2008 at 10:12 | No commentsCategories: EDA/PLDShort Content: Because the liquid-crystal display has the low pressure, the micro power loss, the demonstration information content to be big, volume small and so on characteristics, in domains and so on mobile communication terminal, portable computer, GPS satellite positioning system has the widespread use, becomes the amount of use biggest display device. The liquid crystal display controller is usually composed as the liquid crystal driving circuit's core part by the integrated circuit, through provides the succession signal and the demonstration data ... -
Realizes the real-time data correspondence using the GSM short note
Tuesday, November 18th, 2008 at 04:45 | No commentsCategories: Communication NetworksTags: GSM module, MCUShort Content: Carries on the long range data transmission using the GSM short note, in some situations is one kind of quite good choice. In many literature introduced the related GSM module function, the use, as well as AT order and so on, but in the practical application also many technical detail must consider. Moreover the correspondence is carries on the complex environment, the GSM module besides receives this system interior effective order, the data, will also receive some other information, the ... -
Based on VerilogHDL background noise deduction circuit design
Monday, November 17th, 2008 at 03:12 | No commentsCategories: EDA/PLDShort Content: Abstract: A design of circuit which can deduct background noise based on VerilogHDL is introduced in this paper. Compared with the circuit used chips of the forward and backward counters, its interface with MCU is more simple and operation of software is more easy. Key Word: VerilogHDL, background noise, deduction 1 introduction In the weak signal detection method, often needs to cause the direct-current quantity after the electro-optical modulation transforms for the exchange signal carries on ... -
The use based on dodges MCU which saves to realize the user data to save - en.51rd.net
Saturday, November 8th, 2008 at 19:49 | No commentsCategories: StorageShort Content: Still uses the micro controller's majority equipment also to need some kind of mechanism saves when the power failure to these establishment data which remembers. For example, after replacing the battery cannot remember the preinstall broadcasting station's radio definitely not obtain the very big success in the market. The user hoped the affection the broadcasting station, the preinstall temperature, the parameter choice and other permanent information can preserve for a long time for each time starting when uses directly. ... -
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. Its working voltage is 1.8~3.6 V, when normal work the power loss may control in 200μA about, the low power loss pattern may realize 2μA even O.1μA low power loss. The MSP430 series monolithic integrated circuit already obtained the widespread application as performance outstanding MCU in China. MSP430 has the high integration ... -
Based on MCU many machine parallel correspondence - 51rd Chinese electronic net
Sunday, September 21st, 2008 at 10:31 | No commentsCategories: SCMTags: Many machine correspondence, MCUShort Content: Abstract: Monolithic integrated circuit's many machine serial communication application is very widespread, but when the serial port is taken must carry on many machine correspondences must adopt other measures. This article introduced one kind of use and the mouth carry on many machine correspondences the methods, in reality obtained the confirmation. Key word: MCU, and mouth correspondence 1. Question statement In some system has used three group serial interface sensors (GPS, pressure and wind direction) and three groups ... -
Uses PIC16F639 the passive non-key entrance guard system design
Friday, September 19th, 2008 at 12:14 | No commentsCategories: SCMShort Content: Exempts holds type passive non-key entrance guard (PKE) to become the automobile long-distance non-key entrance guard application rapidly the mainstream, and becomes new vehicle the universal option. This method does not need with the hand to lock or to turn on the vehicle door according to the transmitter button, so long as has an effective responder to be possible to pass in and out the vehicles conveniently. Exempts holds type PKE application request base depot and between the ... -
Does not need to replace battery’s digital countdown timer
Wednesday, September 17th, 2008 at 08:31 | No commentsCategories: SCMShort Content: Only needs MCU, LCD, the 32kHz crystal oscillator as well as a resistor then constitutes a basic countdown timer, moreover only needs an ordinary button battery then to realize surpasses 10 year operating time continuously, as shown in Figure 1. For example, this kind of countdown timer may use in the restaurant providing the servicing time to guarantee that the service personnels press down a button then to start the countdown timer, the micro controller starts the automatic countdown, ... -
Based on the ARM nucleus ADμC7024 in medical electron application
Monday, September 8th, 2008 at 09:48 | No commentsCategories: SCMShort Content: 0 introductions Along with information technology's rapid development and living standards' enhancement, promoted the medical service electronic installation's development enormously, now the medical service electronic installation's trend of development is the high accuracy, timeliness, the low power loss and light-sized, takes in the medical service electronic installation core status MCU (microprocessor) also forward unceasingly to evolve along with this trend of development. Develops present 32 RISC from early 8 MCU (simplification set of instructions computer) MCU. American ADI Corporation ...
