视觉暂留，编程从一个I/O口输出一扫频信号，驱动一支LED灯闪动，频率范围为10HZ~99HZ，扫描时间为30秒，在LED闪动期间观察，一旦发现无法识别LED灯闪动时，按下按键K1，立即停止输出，并将此时的信号频率显示在数码管上，该信号的周期为测试者的视觉暂留时间。-Persistence of vision, programming from an I/O port outputs a sweep signal to drive an LED light flashing, the frequency range of 10HZ ~ 99HZ, scan time of 30 seconds, the LED flashing during the observation, once found it impossible to identify the LED lights flashing, press the key K1, immediate cessation of the output, and at this time the signal frequency displayed on the digital control on the test cycle of the signal" s persistence of vision time.

This experimental report on the multi
这篇实验报告是关于单片机多路数据采集的，本实验由2大部分组成：1、为用EPOROM构成的心电信号发生器；2、为多路信号的微机采集与显示；第一部分实验主要研究可编程序存储器EPROM的非计算机应用。把存储在EPROM中的数字心电信号读出并通过D/A转换为模拟信号显示在示波器屏幕上。
第二部分实验的目的是研究一个数据采集系统，该系统利用ECD-51型单片机为中心，由D/A芯片等将各种低频信号以及由EPROM产生的模拟人体心电信号变换成离散的数字信号存入微机内存，以待进行数据处理和分析，然后再通过D/A转换将其还原成模拟信号显示在示波器的屏幕上。
-This experimental report on the multi-SCM data acquisition, the experiment by the two major components : 1. EPOROM pose for the use of the ECG signal generator; 2, multi-path signals in the computer acquisition and display; the first major study of experimental programmable EPROM memory in non-computer applications. Stored in the EPROM of ECG read out by D/A conversion of analog signals displayed on the oscilloscope screen on. Part II The purpose of this experiment is to study a data acquisition system, which uses ECD-51 microprocessor as the center, from the D/A chips, and other various low-frequency signal from EPROM and the simulation of human ECG transform into several discrete signal words into computer mem
