Monolithic integrated circuit system multi-serial port design technique research_serial, microcontroller, serial port
Saturday, December 5th, 2009 at 22:21 | No commentsCategories: Embedded systemShort Content: 1 introduction In take monolithic integrated circuit as in core observation system. The micro controller often needs two either two above serial ports carries on the communication with other main engines or the peripheral device, how to cause the system to have many serial interfaces, is one has the universal question. Especially in aerospace field, because GPS, the air data system, the digital compass, the radio altimeter, even aviation electronics and so on top generally select the serial communication ... -
51 monolithic integrated circuit
Wednesday, November 4th, 2009 at 04:22 | No commentsCategories: Embedded systemTags: 51, serial portShort Content: Abstract: In take the monolithic integrated circuit as in the core multistage distributional systems, needs to expand the monolithic integrated circuit frequently serial to pass unguardedly, this article introduced separately based on the SP2538 special-purpose serial port expansion chip and the Intel8251 two serial port expansion method, and has given the actual hardware circuit principle and the corresponding correspondence segment.Key word: Serial port expansion; Monolithic integrated circuit; SP2538; Intel8251 1 introduction In the research stope gas accumulation ... -
Realizes - en.51rd.net based on the computer serial port DSP program load
Monday, September 7th, 2009 at 15:50 | No commentsCategories: DSPShort Content: Outline In the embedded system DSP software's performance history, is simulator's to the DSP software carries on the online debugging and the load compared with the general method through DSP on JTAG port which provides using the manufacturer. This method is convenient in the software debugging stage, but in the complex embedded system, the DSP system is only possibly an overall system's part. After completing system docking, DSP subsystem and overall system adjusting work, once has the problem, needs separates ... -
Based on the STC monolithic integrated circuit and GPRS chart article LED screen
Tuesday, May 26th, 2009 at 18:39 | No commentsCategories: SCMShort Content: 1 preface GPRS (General Packet Radio Service, general grouping wireless service) the appearance has used the existing GSM network fully, is not only suitable for interrupted, burst characteristics or frequent, the few data transmission, is also suitable for the occasional great data quantity transmission. It causes the mobile communication and the data net combines, it uses "the packet switching" (Packet Switch) the concept develops a set of wireless transmission mode, but uses the existing radio-frequency spectrum highly effective, is the ... -
Modbus the RTU communication protocol realizes - en.51rd.net on MCF51QE128
Thursday, December 11th, 2008 at 03:42 | No commentsCategories: Communication NetworksShort Content: Introduction The industrial control moved toward the centralized monitor, the collection and distribution control from the single plane control, now entered the network intensive manufacture time. Industry controller Lian Wang has also provided for the network management conveniently. Modbus is in the industry controller's network protocol one kind. The Modbus agreement is applies on the electronic controller's one kind of communication protocol. Through this agreement, the controller, the controller (e.g. ethernet) and between other equipment may correspond by way ... -
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 C8051F020 general serial port adapter’s design
Monday, November 17th, 2008 at 19:52 | No commentsCategories: Communication NetworksShort Content: 1 introduction Serial communication's widespread application may cause each kind of transmission facility organically to be united as one body, can carry on the data exchange and the information transmission reliably safely. But because on each equipment transmission channel's signal is different, applies the serial port are also various, must complete the numerous equipment correspondences, inevitably must involve to each equipment's between serial port transformation question. In order to cause computer's RS-232 connection to carry on the correspondence with each ... -
