430的段式液晶的小程序，自己也是新手，大家分享下(msp430 and LCD code)

7128芯片设计原理图，适合3A一下电流的步进电机驱动器设计，非常实用(7128 chip design schematics for what current 3A stepper motor driver design, very practical)

Abstract—Selection combining cascaded with maximum-ratio combining (SC/MRC), which is particularly useful when site diversity is available, combined with low-density parity-check (LDPC) codes is able to combat the effects of fading. The biterror rate (BER) expressions of uncoded SC/MRC and SC/MRC with LDPC codes over an independent and identically distributed Rayleigh-fading channel are derived based on the Gaussian approximation approach. These expressions are also applicable to the selection combining and maximum-ratio combining as special cases. The derived expressions are in good agreement with simulation results and approach the density evolution (DE) thresholds. These expressions are able to achieve a significant reduction in computational time with a reasonable accuracy for analyzing the BER performance as compared to simulations and DE.

* 通过本例程了解 DS1302时钟芯片的基本原理和使用 ,理解并掌握DS1302时钟芯片驱动程序的编写以及实现数字字符在数码管中的显示(By understanding this routine DS1302 clock chip on the basic principles and use, understand and grasp the DS1302 clock chip driver for the preparation and the realization of numeric characters in the digital tube display)

说明：  PADS库文件,比较合适下载，分享给使用PADS的用户，我为人人，人人为我(The pad library file is suitable for downloading and sharing to users of pads. I am everyone and everyone is me.)

底层调用了PCSC的通信库Winscard，可用于PC上读卡器与智能卡的通信(It calls the underlying communication library Winscard PC can be used on a PC to communicate with the smart card reader)

一个完整的ASM程序，用于通过SPI口采集7022电能量，2404储存，双计度器显示，485通讯，掉电保护功能。此程序配合硬件已是一成熟产品(A complete ASM procedures, through the SPI port for collecting electric energy 7022, 2404 storage, dual display of degrees, 485 communications, power-down protection. This procedure with the hardware is already a mature product)

超全的AD库 包含了比较全的一些常用库文件,常用51单片机以及C8051F系列，还有一些常用的IC(Ultra-wide AD library contains more full of some commonly used libraries, common C8051F series microcontrollers and 51, there are some common IC)

基于链式STATCOM的三相不平衡负载的平衡化补偿(Three-phase STATCOM based chain balancing of unbalanced load compensation)

神经网络中的权值、阈值以及中间变量很多，但是单片机的程序区和数据区的容量都是有限的。89C52程序区为8K字节，数据区为256K字节。由于探测器受体积限制应尽量避免外扩存储器，所以在实现计算时，要将权值和阈值写成立即数形式减少资源占用。(Neural network weights, threshold and intermediate variables, but procedures for single-chip area and the volume of data are limited. 89C52 process area for 8K byte, 256K-byte data area. As the detector by the volume limit should be avoided as far as possible outside the extended memory, so in the realization of the calculation, the right to the threshold value and written in the form of an immediate reduction in the number of occupied resources.)
