The purpose of this application note is to describe the main elements of an RS-422 and RS-485 system. This application note attempts to cover enough technical details so that the system designer will have considered all the important aspects in his data system design. Since both RS-422 and RS- 485 are data transmission systems that use balanced differential signals, it is appropriate to discuss both systems in the same application note. Throughout this application note the generic terms of RS-422 and RS-485 will be used to represent the EIA/TIA-422 and EIA/TIA-485 Standards.

《多傳感器數據融合手冊》 《Handbook of Multisensor Data Fusion》 作者: David L. Hall 定價: USD 199.95 出版社: CRC 出版年: 2001-06-20 簡介 · · · · · · Multisensor data fusion is an emerging technology with important applications in both the military and civilian sectors, such as target recognition, robotics, medical diagnostics, and "smart" buildings. It draws on techniques from wide-ranging disciplines, including artificial intelligence, pattern recognition, and statistical estimation. This handbook is an up-to-date, comprehensive resource for data fusion system designers and researchers. Top experts in the field lead readers from a basic introduction and survey of data fusion technology to advanced mathematics and theory and to some very practical advice for systems implementers.

This leon3 design is tailored to the Altera NiosII Startix2 Development board, with 16-bit DDR SDRAM and 2 Mbyte of SSRAM. As of this time, the DDR interface only works up to 120 MHz. At 130, DDR data can be read but not written. NOTE: the test bench cannot be simulated with DDR enabled because the Altera pads do not have the correct delay models. * How to program the flash prom with a FPGA programming file 1. Create a hex file of the programming file with Quartus. 2. Convert it to srecord and adjust the load address: objcopy --adjust-vma=0x800000 output_file.hexout -O srec fpga.srec 3. Program the flash memory using grmon: flash erase 0x800000 0xb00000 flash load fpga.srec

What Does the code DO? Sometimes we may desire to hide our file contents from others.One of the possible way is encrypting these files.Here a simple encryption technique is used(In VB - The same technique can be implemented in "c" also.) Program flow Explained * Open the File to be encrypted for Binary Access Read(Say Source File) * Open a temparory file where encrypted data is stored for Binary Access Write(Say Destination File) * Loop through the Source File Byte by Byte * For each byte read from the file, Complement the data. (Using Not operator (in C we have to use "~" operator) * Write Complemented Data to Destination File * Delete the Source File * Rename Destination file as Source File(Now Encryption is over)

This C++ code example provides a method for transferring objects or chunks of data from one device to another via the Bluetooth OBEX protocol. These chunks are typically files or other blocks of binary data. This example demonstrates how to run OBEX on top of the Bluetooth RFCOMM protocol, but OBEX can also be used with other transport media, such as IrDA and USB.

BlueCore supports a mechanism called Device Firmware Upgrade (DFU) to enable its software and configuration data to be replaced. To guard against unauthorised changes, downloaded files can be verified by means of signatures. The DFU Tools are a suite of programs that enable firmware and persistent store files to be signed and combined to form DFU files.

From the point of view of quality management, it is an important issue to reduce the transmission time in the network. The quickest path problem is to 6ndthe path in the network to senda given amount of data from the source to the sink such that the transmission time is minimized.

This application report describes the use of Timer_A3 to decode RC5 and SIRC TV IR remote control signals. The decoder described in this report is interrupt-driven and operates a background function using specific features the Timer_A3. Only a small portion of the MSP430 CPU?s nonreal-time resources is used. Specific hardware bit-latching capabilities of the Timer_A3 module are used for real-time decoding of the IR data signal, independent and asynchronous to the CPU. CPU activity and power consumption are kept to an absolute minimum level. The Timer_A3 decoder implementation also allows other tasks to occur simultaneously if required. The solutions provided are written specifically for MSP430x11x(1) and MSP430x12x derivatives, but can be adapted to any other MSP430 incorporating Timer_A3. 電視遙控器設計基於MSP430

Welcome to the software files for the ADS8361 to TMS320F2812! There are two project files in each of the folders McBSP, SPI and Both. Mode II and IV are explored using the McBSP port alone, as well as the SPI port. These projects are located in the SPI and McBSP folders. Modes I and III are explored using both McBSP and SPI. In Mode I, the M0 and M1 pins are controlled by use of the jumper on the evaluation module. A0 is controlled by the DX pin of the McBSP port. In Mode III, the A0, M0 and M1 pins are controlled via GPIO functions of PortF. The "SRC", "CMD" and "INCLUDE" files in the archive are from "C28x Peripheral Examples in C" (document # SPRC097). If you have questions about this or other Data Converter products, feel free to e-mail us at:
