Based on hardware arbitration and serial main line’s many machine correspondence
Friday, December 5th, 2008 at 21:02 | No commentsCategories: Communication NetworksShort Content: Abstract many monolithic integrated circuits through the serial total dimension serial interface (I2C, SPI) the memory chip may constitute simple and direct, the highly effective multi-main engine system. The multi-main engine system needs to solve uses in common the serial main line's arbitration question, this article gives use first encoder 74HCl48 and decoder 74HCl38 realizes the hardware arbitration solution. Realizes the bus arbitration with the software to compare, this method simple reliable, timeliness is high, may realize main line's appointment ... -
In monolithic integrated circuit SPI correspondence data stream synchronized question research
Saturday, November 22nd, 2008 at 10:59 | No commentsCategories: Communication NetworksShort Content: The abstract detailed introduction serial synchronous communication's characteristic, showed how guarantees the data stream through the hardware design and the software error correction the synchronization; Gives one kind of correction data displacement the method, and carries on the explanation take digital signal processor TMS320LF2407A and between the monolithic integrated circuit MsP430F135 SPI correspondence as the example.Key word SPI serial synchronous communication MSP430F135 TMS320LF2407A SPI is the serial peripheral device connection (Serial Peripheral Intcrface) the abbreviation, usually is called "the ... -

Based on TMS320LF2407 DSP controller pronunciation module design
Wednesday, November 5th, 2008 at 04:36 | No commentsCategories: DSPShort Content: Abstract: This article introduced emphatically DSP the chip SPI synchronization serial interface and SPI and the pronunciation transformation chip AD50 mailing address, has given the hardware circuit design. In view of AD50 characteristic, when software design carries on the initialization disposition through the DSP SPI mouth to it, causes its normal work. DSP processes in the interior to the voice signal and through the AD50 output. Key words: Digital signal processor DSP Synchronized serial interface SPI pronunciation module AD50 initialization ... -
TMS320C5402 and MAX147 connection design
Saturday, August 16th, 2008 at 21:49 | No commentsCategories: DSPShort Content: 1 TMS320C5402 MCBSP working MCBSP is the TMS320C5402 multichannel cushion serial port (MCBSP0 and MCBSP1). MCBSP exterior is connected through 6 base pins and other serial components, in internal and DSP essence connection. The serial data receiving and dispatching base pin and the internal each serial port register are connected. According to the MCBSP function and the structure, may its working summary be: SPI working and multichannel cushion working. This article mainly introduces the SPI operating mode. The MCBSP exterior base pin is: ...
