KEYTEST

汇编子程序 大学课程设计需求者的最爱-compilation subroutine university curriculum design needs a favorite

说明：  在单片机中，可以实现串口调试，带按键操作的功能(Serial port debugging with keystroke operation)

常见的debug命令,与大家共同分享一下-common debug orders, we share common

LPC2000 启动代码Start.s文件简要分析 先说一下启动代码的位置，启动代码是在板子加电后首先执行的。所以非要用汇编来写才行。 要完成处理器模式的初始化、设置中断向量表、设置各个模式下的堆栈、初始某些变量从而把 系统带到一个合适的运行环境中开始用户程序的运行。 本段设置处理器的模式相关常量

压力采集程序，能够通过外接传感器来测量显示压力并做处理-Pressure acquisition program can be displayed by external sensors to measure pressure and to do deal with

MASM example of FadeIn FadeOut Transparency effect

该程序是用VC++编写的程序，是关于SQL语句中设置多个字符串检索条件方面的，成品语句，可以独立运行，参考价值较高。(The program is VC++ Preparation procedures on the SQL statement string to set up a number of search terms, finished statement, can run independently, a high reference value.)

A/D转换子程序，根据单片机的读写时序以及其丰富的I/O接口，利用汇编编程，实现模-数转换功能。-A/D conversion subroutine, in accordance with the read and write single-chip timing, as well as its wealth of I/O interface, using the compilation of programming, to achieve mold- digital conversion function.

蜂鸣器在单片机上的应用,汇编语言,附原理图及说明学习文档 蜂鸣器的正极性的一端联接到5V电源上面，另一端联接到三极管的集电极，三极管的基级由单片机的P2.4管脚通过一个与非门来控制， 用户可以通过程序控制P2.4管脚的置低和置高来使蜂鸣器发出声音和关闭。 蜂鸣器的声音大小及音调可以通过调整P2.4管脚的置高时间及输出的波形进行控制，这一点可以在调试程序的时候来试验。-On the buzzer in single-chip applications, assembly language, with a schematic diagram and instructions to study documents the positive polarity of the end of the buzzer connected to the 5V power supply above, the other end connected to the transistor" s collector, the base level by the single-chip transistor Machine P2.4 pin through a NAND gate to control, the user can be programmed to set pin P2.4 low and set high to make the buzzer sound on and off. Buzzer sound size and pitch can be set by adjusting the P2.4 pin of the high time and output waveform control, and this point could be the time to test the debugger.
