This a simple bootloader for AT91SAM7{S,X}{64,128,256} processors. It permits you to download new code to the device over USB. This bootrom is installed at address 0x00000000 in the ARM, which means that it is the first piece of code to execute after reset. At startup, it waits for a few seconds to see if the downloader is trying to connect. If not, then the bootloader gives up control and jumps to your program. If the downloader is trying to connect, then the bootloader receives the new program over USB and writes it into flash.

Hey. This some pid code for the atmega88 that I once used to control a heater. It s purpose is pretty specific, and I only wrote it to work on the mega88, so the code itself won t be too useful. It is a good place to start if you re trying to use or figure out pid though.

Universal Serial Bus (USB) is a communications architecture that gives a personal computer (PC) the ability to interconnect a variety of devices using a simple four- wire cable. The USB is actually a two-wire serial communication link that runs at either 1.5 or 12 megabits per second (mbs). USB protocols can configure devices at startup or when they are plugged in at run time. These devices are broken into various device classes. Each device class defines the common behavior and protocols for devices that serve similar functions. Some examples of USB device classes are shown in the following table

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

Example to support XML files using MSXML. ========================================= XML (Extensible Markup Language) is a commonly used basis for representing a huge range of structured data file formats. The specification is maintained by the World Wide Web Consortium (W3C?. This plugin is intended as an example of how XML data can be read with a DataPlugin. You can adjust it to meet the needs of your own XML file format. After installing the URI file (double click on it), you can find the VBScript file located at "C:\Program Files\National Instruments\Shared\USI\plugins\DataPlugins\XML Example" You can make changes to this file to read your specific XML file.
