Based on DSP three axle track turnplate servocontrol design
Tuesday, November 4th, 2008 at 22:29 | No commentsCategories: DSPShort Content: Abstract: This article introduced with realizes based on the TMS320F2812 three axle track turnplate servocontrol's design. Replaces the turnplate tradition using "the exchange servo electrical machinery reduction gear" the direct-current moment of force electrical machinery direct drive load way; Using DSP and CAN bussing technique; Using on, the lower position machine coordination control's method, enables the system to satisfy the ultra low speed, the width velocity modulation, the high accuracy, the redundant reliable request. Key word: Three ... -
Expansion realizes - en.51rd.net based on enlargement mode SPI the connection large capacity Flash
Friday, October 17th, 2008 at 23:54 | No commentsCategories: StorageShort Content: 1 introduction Along with information age's arrival, each kind of information's integration and is alternately getting more and more frequent. In the motion control system needs to process the information content which and to save also to grow day by day, majority of motion control system's core component MCU oneself already integrated the large capacity memory (to compare with beforehand MCU), but depends upon MCU own memory to be very generally difficult merely to satisfy the system to the large ... -
Based on GIO/FVID DSP video processing driver - 51rd Chinese electronic net
Monday, October 6th, 2008 at 07:28 | No commentsCategories: DSPShort Content: The abstract take based on the TI Corporation TMS320F2812 DSP video processing system as an example, designs the GTO/FVID model in the DSP/BIOS foundation the video equipment first floor driver, provides the convenience for the high-level application procedure development personnel the API connection function to operate the first floor video equipment, raised the video processing system's development efficiency. Elaborated the video equipment driver method of exploitation, has well to the similar video processing platform may profit from the nature.Key word ... -
8051st, ARM and DSP instruction cycle test and analysis
Saturday, September 20th, 2008 at 07:17 | No commentsCategories: SCMShort Content: The abstract in the real-time embedded control system, the instruction cycle has the very important influence to system's performance. Introduced that several kind of most commonly used micro controller's working mechanisms, use a section of cyclic sentence to carry on the test to these kind of micro controller's instruction cycle, and carries on the analysis comparison. The analysis conclusion has certain instruction function to central controller's choice. The key word instruction cycle tests AT89S51 LPC2114 TMS320F2812 When the real-time control ... -
Based on DSP precision semiconductor laser actuation electrical power system
Wednesday, September 17th, 2008 at 21:23 | No commentsCategories: DSPShort Content: Abstract: This article introduced one kind of DSP control's semiconductor laser actuates power source's design. The main power source uses the electric current negative feedback type constant current electric circuit, the control and the protection circuit take TI Corporation's TMS320F2812 as a core, the sur- periphery driving circuit and the hardware protection circuit, DSP can the accuracy control output current size.Key word: DSP; TMS320F2812; Semiconductor laser; Constant current Introduction At present, semiconductor laser (LD) has widely applied in the correspondence, ... -
eCAN module and SJA1000 application comparison
Thursday, July 31st, 2008 at 01:46 | No commentsCategories: DSPShort Content: Introduction TMS320F2812 is the DSP chip which TI Corporation promotes newly, in inlays CAN the bus control unit eCAN module (below Jian Chengwei eCAN), performance existing DSP (for example TMS320C24x) in inlays the controller has the very big enhancement; The data transmission is more flexible conveniently, the data quantity is big, the reliability is higher, the function is more complete. But SJA1000 is the new independent CAN controller which the Philips semiconductor company promotes, is the PCA82C200 substitution product, supports the ...
