基于Intel 8253定时器的两端Asm,包括配套电路,流程图
1。设计基于ISA总线的Intel 8253 的接口电路,用Intel 8253 的1个通道作定时器,演奏C调的各个音符,利用查表程序的方法依次演奏,每个音符演奏1s,停0.5s 演奏三遍后退出程序
2。利用Intel 8253的一个通道产生一个100Hz的方波,用示波器测试信号的正确性
以产生的方波作为另一个通道门控信号。利用此通道测量其高电平的宽度,在PC机显示屏上显示其数值并退出程序

LANDSCAPE SOURCE
There is a makefile, two C sources and one ASM file here. As it should
always be, the ASM stuff contains the innermost pieces of code for the
effect, and also some other stuff related to low-level keyboard input.-LANDSCAPE SOURCE

伟福LAB2000单片机仿真系统直流电机控制:利用实验仪上的D/A变换电路,输出-8V至+8V电压,控制直流电机。改变输出电.压值,改变电机转速,用8255 的PB.0 读回脉冲计数,计算电机转速。在电压允许范围内,直流电机的转速随着电压的升高而加快,若加上的电压为负电压,则电机会反向旋转。本实验仪的D/A变换可输出-8V到+8V的电压,将电压经驱动后加在直流电机上,使其运转。通过单片机输出数据到D/A变换电路,控制电压的高低和正负,观察电机的旋转情况。
在电机转盘上安装一个小磁芯,用霍尔元件感应电机转速,用单片机控制8255读回感应脉冲,从而测算出电机的转速。
