当前LCM的主流接口有并口和串口。并口引脚多，产生串扰，串口则没有诸如此类的缺点。SPI作为串口家族的一员，具有高速同步、芯片管脚少和信号稳定不产生串扰等优点，越来越受到开发人员的青睐。但是，具有SPI的LCM并不是毫无缺点的，市场上以COG(chip on glass)方式封装的LCM大都是基于单工方式传输的，这将给开发带来了非常大的麻烦。本文主要论述基于单工SPI的GUI开发方案，详细地分析了基于单工SPI的GUI的开发开台，论述并分析在GUI开发过程中遇到的问题，最后提出增加虚拟LCD的方案解决这个问题。

是英文 “ Surface mount technology ”的缩写。即表面安装技术，这是一种较传统的安装方式。其优点是可靠性高，缺点是体积大，成本高，限制 LCM 的小型化。 是英文 “ Chip On Board ”的缩写。即芯片被邦定(Bonding)在PCB上，由于IC制造商在LCD控制及相关芯片的生产上正在减小QFP（ SMT 的一种）封装的产量，因此，在今后的产品中传统的 SMT 方式将被逐步取代。

This program would work fine only with a specific flash tool through PC printer port under EPP mode.Program is capable of identifying flash chip manufacturer, device type, capacity,... It also allows user to dump flash data, edit/revise the content of flash chip on the Screen, and re-write them back to the chip.

Libnet is a generic networking API that provides access to several protocols. It is not designed as a all in one solution to networking. Currently many features that are common in some network protocols are not available with Libnet, such as streaming via TCP/IP. We feel that Libnet should not provide specific features that are possible in other protocols. If we restrict Libnet to the minimal needed to communicate (datagram/packets) then this allows it to support more interfaces. 很好的学习linux网络变成的源码

内存管理程序，功能与FASTMM相似，PLEASE NOTE: There are two ways to install BigBrain. You may use the memory manager code natively compiled into your EXE or you can use an included external DLL which will allow you to share memory across multiple DLLs with one central place for memory management. Using the DLL allows your application to share strings, and serves the same purpose as the ShareMem unit included with Delphi. BigBrainShareMem.dll should be 100％ compatible with the DelphiMM.dll and could even simply be renamed to DelphiMM.dll to simplify deployment.

The MAX481E, MAX483E, MAX485E, MAX487E–MAX491E, and MAX1487E are low-power transceivers for RS-485 and RS-422 communications in harsh environments. Each driver output and receiver input is protected against ±15kV electrostatic discharge (ESD) shocks, without latchup. These parts contain one driver and one receiver. The MAX483E, MAX487E, MAX488E, and MAX489E feature reduced slewrate drivers that minimize EMI and reduce reflections caused by improperly terminated cables, thus allowing error-free data transmission up to 250kbps. The driver slew rates of the MAX481E, MAX485E, MAX490E, MAX491E, and MAX1487E are not limited, allowing them to transmit up to 2.5Mbps.

Generating Fractals with SSE/SSE2 You probably have heard about fractals before. They are beautiful pictures such as the one shown above. Any fractal can be described using iterative formulas. So you can generate a fractal by evaluating these formulas and finding the color of each pixel. That is a large computational task, and drawing a fractal needs a fast CPU and a carefully optimized program.
