此系统是本人做毕业设计时候的老东西了，是汇编写的。可以在PROTEUS上仿真，实际效果和仿真效果一模一样，电梯的功能相信大家都很了解，我就不在这多讲了。但要说明的一点是：我这个系统是仿真用的，有些东西不能和现实中的电梯相比，里面可能有某些方面考虑的不是很周到，希望有心的朋友提点意见，谢谢我的E-MAIL:qq317999920@163.com-This system is designed when I graduated to do the old things is a compilation of writing. Be able to PROTEUS on the simulation, the actual results and simulation of the effect of exactly the same as the functions of elevator think we all understand that I am not in this more than a speech. But the point is to explain: I used this system is the simulation of, some things can not be compared to the reality of the elevator, which may have to consider certain aspects of the not very thoughtful, I hope interested提点意见Friend, thank you my E-MAIL: qq317999920@163.com

EM78P153用PWM设计的源代码，其中有详细的说明。

这个源代码是可运行的。-the source code can be run.

一个背单词源码，用masm写成，作者zhasm 只是觉得其构思不错，版权归原作者所有-a source word back with masm languages, the author zhasm just think that the idea is true, All the property of authorship

系转载,液晶控制器T6963的C语言驱动程序，T6963应用广泛，特别是240×128的液晶基本上都是用这个芯片

很好的多功能数字钟的HDL代码不可多得的哦-Good multi-function digital clock of the HDL code rare Oh

将存于DAT1开始的1个8字节BCD相加,结果放在SUM.考虑溢出.-will be stored in the DAT1 began an eight-byte BCD together, the results on SUM. Consider spills.

在集成电路中，通常采用T型解码网络实现数字量往模拟的转换，再利用运算放大器完成模拟电流变为模拟电压的转换。所以，要把一个数字量变为模拟电压，实际上需要两个环节，先把数字量变为模拟电流，这是由D/A转换器完成的；再将模拟电流变成模拟电压，这是由运算放大器完成的。有时D/A转换器芯片只包含前一个环节，有些D/A转换器则包含两个环节，用前一种芯片时，需要外接运算放大器才能得到模拟电压。-In integrated circuits, the usual T-decode digital networks to analog conversion, and then complete the simulation of the use of op-amp current into the analog voltage conversion. Therefore, it is necessary to become a digital simulation of voltage, in fact, need two links, first into a digital simulation of currents, this is determined by D/A converters completed then simulate current into the analog voltage, this is determined by computing completed amplifier. Sometimes D/A converter chip contains only a part before, some D/A converter includes two aspects, before a chip, the need for external op-amp voltage can be simulated.
