Monolithic integrated circuit beginner several are not easy the concept which grasps_MCU, beginners
Monday, November 9th, 2009 at 09:22 | No commentsCategories: Embedded systemShort Content: First, main line: We knew that an electric circuit always becomes by the primary device through the electric wire connection, in analogous circuit, including a segment into question, because between various components is the serial relations generally, between various components' segment are not many, but the computer electric circuit is actually dissimilar, it is take the microprocessor as the core, various components must be connected with the microprocessor, between various components' work must the intercoordination, therefore needs the segment ... -
51 monolithic integrated circuit assembly simulation serial port signal procedure_MCU, 51, compiled
Saturday, November 7th, 2009 at 14:11 | No commentsCategories: Embedded systemShort Content: Assembly compilation simulation serial port signal procedure T2 as baudrate controlUART_RXD interrupts 0 or 1 hardly, if can enter the interrupt, explained that this line has an outset position production, after entering the interrupt, movesWith the following receive procedure. Before withdrawing from the hard interrupt, also needs to interrupt the symbol to reposition hardly.UART_TXD is any other IO then.

51 monolithic integrated circuit address pointer and application_MCU, 51
Friday, November 6th, 2009 at 01:02 | No commentsCategories: Embedded systemShort Content: 51 monolithic integrated circuit exterior RAM address space is 64K, the address bus is 16, visit external connection RAM may carry out the following 4 instructions: MOVX A,@DPTR MOVX @DPTR, A MOVX A,@RI MOVX @RI, A And DPTR is 16 bit address register, address high 8 save in DPH, address low 8 saves in DPL; Ri(I=0,1) is 8 registers, takes when the address pointer only saves the low 8 bit address. MCS-51 carries out above instruction is ... -
In monolithic integrated circuit system
Wednesday, November 4th, 2009 at 10:09 | No commentsCategories: Embedded systemShort Content: Abstract: Needs to demonstrate when the Chinese character are many, in the monolithic integrated circuit system's Chinese character code is tedious. This article introduced that one kind takes the monolithic integrated circuit system's Chinese character code directly using the PC machine Chinese character encoding, simplifies system's design. Key word: Monolithic integrated circuit liquid-crystal display 29F040 Chinese character demonstrationIntroduction In the modern industry control and in some intellectualization instruments and meters, more and more places need to use ... -
The monolithic integrated circuit explains method and dealing with strategy_MCU, crack
Friday, October 23rd, 2009 at 22:59 | No commentsCategories: Embedded systemShort Content: Abstract: Introduced the monolithic integrated circuit interior password explains the commonly used method, showed with emphasis the invasion strikes/the physics method of attack detailed step, finally, from application angle embarking, proposed copes with several suggestions which explains. 1 introduction The monolithic integrated circuit (Microcontroller) has internal ROM/EEPROM/FLASH generally for the user depositing procedure. In order to prevent without authorization to visit or the copy monolithic integrated circuit within the aircraft the procedure, the majority of monolithic integrated circuits ... -
Lengthens the battery service life using the dual processor
Wednesday, October 7th, 2009 at 09:24 | No commentsCategories: DSPShort Content: Turns toward a lower power loss, the high performance battery to supply the electrical form system development the tendency to be without a doubt. Speaking of the battery supply, the consumer hoped that the portable electronic products can by "the lower electric quantity execution multi-purpose", simultaneously, the numerous manufactured products also start to transfer use the battery power supply. Digital signal processor (DSP) commonly used in request high performance application domain, thus causes the clock running rate to promote unceasingly. ... -
Based on MCU DSP motion control hardware platform design
Tuesday, July 7th, 2009 at 00:55 | No commentsCategories: DSPShort Content: Introduction The open style controller architecture stems from "open style" PC (personal computer) the technology, the present open style movement controller many are the PC movement control card structure, along with MCU (micro controller) and DSP (digital signal processor) the performance enhancement, MUC and DSP substitutes for PC the tendency to be day by day obvious, but this kind of embedded compact structure compares PC to have more widespread adaptability to environment. MCU, DSP and the PC difference is ... -
Studies and realizes - en.51rd.net based on the MCU CPLD phase difference and the frequency measuring technique
Tuesday, May 26th, 2009 at 15:32 | No commentsCategories: SCMShort Content: 1 introduction The phase examination is the electrical power system automatic control harmonious wave analysis and the control key technologies. The traditional phase measurement is (voltage or electric current) transforms using the zero crossing electric circuit the input two groups signals into the square-wave signal, again using the logic circuit and the monolithic integrated circuit technology to the signal some special sector counting and the mathematical manipulation, obtains the phase difference. Along with the programmable component (FPGA, CPLD) fast development, ... -
Flies thinks of Cull Flexis the JM controller series to start USB nimbly the connection the development
Tuesday, May 26th, 2009 at 14:12 | No commentsCategories: SCMShort Content: The universal serial bus (USB) connects has become the serial communication the universal standard, widely applies in each kind of equipment, to the industrial equipment and so on is too numerous to cite individually from the PC peripheral device and the memory stick. Flies thinks of the Cull semiconductor to promote Flexis the JM series micro controller (MCU), may help the designers with ease to integrate the USB connection to various expenses and the industrial application. Flies thinks of ... -
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 ...
