Debugs the UART data receiving and dispatching through the waveform analysis method_RS-485, RS-232, serial communication
Wednesday, October 21st, 2009 at 19:42 | No commentsCategories: Embedded systemShort Content: Abstract: This article through to the asynchronous serial data form's analysis, elaborated that debugs UART data receiving and dispatching through the waveform analysis method the principle and the method. Runs into the beginner frequently, had problems to the monolithic integrated circuit serial communication did not know how to manage situation. Actually the most effective debug method is observes the receiving and dispatching data with the oscilloscope the profile. May determine following situation through the observation profile: ... -
Realizes DSP and the PC machine high speed serial communication using TL16C750_DSP, TL16C750, serial communication
Sunday, October 18th, 2009 at 21:52 | No commentsCategories: Embedded systemShort Content: Abstract: TL16C750 is the asynchronous communication chip which TI Corporation produces, when communications system's timely request is high, may realize system's high speed serial communication through expansion asynchronous communication chip TL16C750, thus enhancement system's correspondence interface control ability. In the article introduced the TL16C750 performance and with the correspondence related register, has given TL16C750 in TMS320C50 and in the PC machine communications system's hardware application electric circuit and TMS320C50 the initialization TL16C750 software programming. Key word: The ... -
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.
