At present widespread has used in each kind of electronic products, the automobile, the expense entertainment, the phantom, the industrial control, the ... -
Based on PIC18 monolithic integrated circuit
Wednesday, December 2nd, 2009 at 02:04 | No commentsCategories: Embedded systemShort Content: 1 introduction RS-485 is an electricity interface specification, it has defined one based on the list to the line of balance multi-spots, bidirectional (half-duplex) the information link, only makes the stipulation to the connection electrical specification, but does not involve the connector, the electric cable or the agreement, based on the user may establish own high-level communication protocol, from that time's point of view is one relative economy has the quite high noise abatement relatively high transmission speed transmitting ... -
Based on uclinux CAN main line embedded actuation programming_uClinux, CAN
Sunday, November 29th, 2009 at 06:01 | No commentsCategories: Embedded systemShort Content: Abstract: Introduced the uclinux operating system's essence structure as well as the equipment actuate the programming the basic principle, and has carried on the hardware design and the software to the CAN main line's embedded system actuates the programming, proposed that the CAN bussing technique applies in embedded system's one kind of plan. 1 introduction The early time applies in eight monolithic integrated circuit software design embedded system mainly before the background system (or ultra circulatory system), the procedure ... -
Realizes the CAN main line correspondence with the PIC18F458 CAN module_CAN, PIC, bus, PIC18F458
Thursday, November 26th, 2009 at 13:55 | No commentsCategories: Embedded systemShort Content: CAN (Controller Area Network) is the controller regional network, is one kind mainly uses in each kind of equipment monitor and the control network. CAN has the unique design concept, good function characteristic and extremely high reliability, scene antijamming ability. It widely was already applied in the domestic and foreign industrial control domain, becomes most has one of career development field buses. The American micro core company's PIC18F458 monolithic integrated circuit integrated the CAN correspondence connection, carries out ... -
Embedded CAN bus control unit and DSP connection
Thursday, October 1st, 2009 at 11:10 | No commentsCategories: DSPShort Content: The field bus is one kind open style, digitized, the multi-spot correspondence control system confined network, in the automated domain most has one of now application prospect technical. The CAN main line is in field bus's application hot spot, the CAN main line supports the serial communication network which the distributional control and at the right moment controls. Because the CAN main line has the correspondence speed to be high, openness is good, the text is short, error correction ... -
Based on DSP high low speed CAN main line automobile control system design
Monday, June 15th, 2009 at 09:35 | No commentsCategories: DSPShort Content: Along with the modern automobile performance's unceasing promotion, the new control function increases unceasingly, like central door lock, light control, glass fluctuation, rear view mirror adjustment, roof louvre window control, chair adjustment and ignition timing control and so on. The traditional control system uses the relay and the independing mode control, causes in the vehicle the group of lines to be excessively many, and the wiring is complex, thus has created the serious electromagnetic interference, causes system's reliable drop. At ... -
AT90CAN128 switch quantity control unit design
Tuesday, May 26th, 2009 at 23:32 | No commentsCategories: SCMShort Content: Introduction CAN (Controller Area NetWork) the bussing technique is one kind supports the distributional control and the real-time control serial communication network effectively, widely applies in the industrial control. Its hardware connection is simple, the reliability is good, timeliness and the performance-to-price ratio are high, can satisfy the computer interlock system communication network well to timeliness and the reliable request. The AVR monolithic integrated circuit is the enlargement mode built-in Flash RISC high speed 8 monolithic integrated circuits which ... -
Enhances CAN using the CAN transceiver the network the secure
Thursday, December 11th, 2008 at 10:22 | No commentsCategories: Communication NetworksTags: CAN, The heat inserts pulls outShort Content: The CAN transceiver must in the very severe under the working conditions guarantee that the data transmission the reliability, this set the very high request to component's electronic performance. The transceiver usually is between the expensive node component and the CAN main line the only connection, therefore Texas Instruments (TI) Corporation's CAN transceiver SN65HVD1050 has many job safety characteristic speaking of the CAN application specially importantly, for example, the anti-electromagnetism (EM) disturbance, the low EM radiation, noise abatement, the static ... -
The CAN bus system’s design with realizes - en.51rd.net
Tuesday, December 9th, 2008 at 20:36 | No commentsCategories: Communication NetworksShort Content: In the field bus concept's appearance to present's in the recent 20 years, already presented several kind of field bus technology and moves toward maturely. And the CAN main line already by the recognition was one of several kind of most promising field buses. CAN is one kind by has the high performance serial data confined communication network which the CAN controller is composed, internationally applies one of most widespread field buses. At first, CAN is designed takes in ... -
The SOPC technology in the electric locomotive transforms the application
Saturday, November 29th, 2008 at 14:55 | No commentsCategories: EDA/PLDShort Content: The abstract introduced briefly Shaoshan 3 4000 are the electric locomotive has the contact control malpractice and the non-contact logical control module LCM basic principle; According to the locomotive control circuit function, designs fu gathers the standard interface standard special-purpose IP; Based on the SOPC design concept, quoted SOPC Builder to integrate 32 NiosII microprocessors, logical control unit IP, CAN on 1 piece of FPGA bus control unit IP and some essential periphery module, gave the logical control module the ...
