On the LPC13xx, programming, erasure and re-programming of the on-chip flash can be performed using In-System Programming (ISP) via the UART serial port, and also, can be performed using In-Application Programming (IAP) calls directed by the end-user code. For In-System Programming (ISP) via the UART serial port, the ISP command handler (resides in the bootloader) allows erasure of one or more sector (s) of the on-chip flash memory.

This application note contains a reference design consisting of HDL IP and Xilinx AdvancedConfiguration Environment (ACE) software utilities that give designers great flexibility increating in-system programming (ISP) solutions. In-system programming support allowsdesigners to revise existing designs, package the new bitstream programming files with theprovided software utilities, and update the remote system through the JTAG interface using theEmbedded JTAG ACE Player.

Frequently, voltage reference stability and noise defi nemeasurement limits in instrumentation systems. In particular,reference noise often sets stable resolution limits.Reference voltages have decreased with the continuingdrop in system power supply voltages, making referencenoise increasingly important. The compressed signalprocessing range mandates a commensurate reductionin reference noise to maintain resolution. Noise ultimatelytranslates into quantization uncertainty in A to D converters,introducing jitter in applications such as scales, inertialnavigation systems, infrared thermography, DVMs andmedical imaging apparatus. A new low voltage reference,the LTC6655, has only 0.3ppm (775nV) noise at 2.5VOUT.Figure 1 lists salient specifi cations in tabular form. Accuracyand temperature coeffi cient are characteristic ofhigh grade, low voltage references. 0.1Hz to 10Hz noise,particularly noteworthy, is unequalled by any low voltageelectronic reference.

目前市场上不少的单片机具有ISP功能。 ATMEL公司最近新推出的AT89SXXXX系列单片机也提供了一个SPI串行接口,让用户能对内部程序存储器编程（ISP）。 什么是 ISP ? ISP（In-System Programming）在系统可编程，指电路板上的空白器件可以编程写入最终用户代码， 而不需要从电路板上取下器件， 已经编程的器件也可以用ISP方式擦除或再编程。ISP技术是未来发展方向。 应一些单片机爱好者的需求,现介绍本站开发的利用串口对89S51及89S52 ISP编程的软件及最简单的硬件连接方法． 下图是个简化了的硬件连接方法,虽然不能全自动的在线编程，但其连接简单实用稳定，比较适于初学的爱好者DIY

Description: Microsoft?Windows?HTTP Services (WinHTTP) provides developers with a server-supported, high-level interface to the HTTP/1.1 Internet protocol. WinHTTP is designed to be used primarily in server-based scenarios by server applications that communicate with HTTP servers. WinHTTP is also designed for use in system services and HTTP-based client applications. WinHTTP is more secure and robust than WinInet. However, single-user applications that need FTP or gopher functionality, cookie persistence, caching, automatic credential dialog handling, Internet Explorer compatibility, or downlevel platform support should still consider using WinInet.

This application note describes the three methods that can be used to program the Flash code memory of the 89C51Rx+/Rx2/66x families of microcontrollers. It discusses in detail the operation of the In-System Programming (ISP) capability which allows these microcontrollers to be programmed while mounted in the end product. These microcontrollers also have an In-Application Programming (IAP) capability which allows them to be programmed under firmware control of the embedded application. This capability is also described

n present power system, the engineers face variety of challenges in planning, construction and operation. In some of the problems, the engineers need to use managerial talents. In system design or upgrading the entire system into automatic control instead of slow response of human operator, the engineers need to exercise more technical knowledge and experience. It is principally the engi- neer’s ability to achieve the success in all respect and provide the reliable and uninterrupted service to the customers. This chapter covers some important areas of the traditional power system that helps engineers to overcome the challenges. It emphasizes the characteristics of the various components of a power system such as generation, transmission, distribution, protection and SCADA system. During normal operating conditions and disturbances, the acquired knowledge will pro- vide the engineers the ability to analyse the performance of the complex system and execute future improvement
