[assembly language] test DL : 0: 一. 实验目的： 1.了解光电开关的使用方法 2.了解利用光电传感器测量电机转速的方法二.光电测速基本原理光电测速的基本电路由光电传感器、计数器和定时器组成。测量时在被测电机主轴上固定一个圆盘，圆盘的边缘上打上小孔。传感器的红外发射端和接收端装在圆盘的两测，电机带动圆盘转到有孔的位置时，红外光通过，红外接收管导通，输出低电平。红外光被挡住时接收管截止，输出高电平。用计数器记录在一定时间内传感器发出的脉冲个数就可以计算出电机转速。三.实验内容 1.接线方法：直流电机计数端接8253 CLK1；8253 CLK0接1MHZ脉冲；OUT0接CLK2；OUT2接8255的PA0；GATE0、GATE2接+5V；GATE1接PC0；8253 CS接280H；8255 CS接288H；DJ接电位器RW1的中间头。 2.编程：利用8253定时器1记录脉冲个数，8253定时器0和定时器2组成10～60秒定时器，测量在一定时间内脉冲个数，算出电机每分钟转速，显示在屏幕上。-1.Understand the operation method of optoelectronics switch 2.The method understood to make use of optoelectronics to spread a feeling machine to measure electrical engineering to turn soon Two.The optoelectronics measures soon basic principle The optoelectronics measures soon basic electric circuit to be spread a feeling machine by the optoelectronics, count a machine and in fixed time the machine constitute.Fix a disk in being measured an electrical engineering principal axis while measuring, beat eyelet on the edge of disk.The red outside blast-off that spreads a feeling machine carries and receives to carry to pack in the disk of two measure, when the electrical engineering arouses a disk to turn to the position of having the bore red outside and only pass, red circumscribe to accept a tube to lead, output low electricity even.Red receive a tube to close while outside and only being held up, output Gao Dian Ping.Use to count a machine record in certain time inside spread the p

[assembly language] control DL : 0: 一、实验目的 1、进一步了解DAC0832的性能及编程方法。 2、了解直流电机控制的基本方法。二、实验内容 1、按图55线路接线。DAC0832的CS接290H～297H，Ub接DJ插孔。8255 CS接288H～28FH。３、编程利用DAC0832输出一串脉冲，经放大后驱动小直流电机，利用开关K0～K5控制改变输出脉冲的电平及持续时间，达到使电机加速，减速之目的。三、实验原理简述小直流电机的转速是由Ub输出脉冲的占空比来决定的，正向占空比越大转速越快，反之越慢。见下面图例：在本实验中，模拟量输出Ub为双极性，当输入数字量小于80H时输出为负，输入等于80H时为0V，输入大于80H时输出为正。因而本实验中，DAC0832输入数字量只有2个（80H和FFH），通过不同的延迟时间达到改变小电机转速的目的-A,Test a purpose 1, the function and plait distance method of further understanding DAC0832. 2, understand the basic method of direct current electrical engineering control. Two,Test a contents 1, press the figure 55 circuits to connect line.The CS of DAC0832 connects a 290 Hs~297 Hs, the Ub connects a DJ socket.8255The CS connects a 288 Hs~28 FHs. 3,Weave a distance to make use of DAC0832 to output a string of pulse, after enlarging, drive small direct current electrical engineering, make use of 0~ K5s of switch Ks control change output pulse of the electricity is even and keep on time, attain to make the electrical engineering accelerated, decelerate of purpose. Three,Test principle Jian Shu Small direct current electrical engineering s turning soon to output sharing of pulse from the Ub is empty ratio to decide, just to share empty compare more and greatly become soon more quick, whereas more slow.See the underneath diagram example: In this experiment, imitate quantity exp
