1. 本程序实现了两个功能,即6264的随机读与写 2. 实现对同一端口既作输出又作输入,如程序中 PORTA作为数据输入输出口； 3. 测试接线方式见Proteus仿真文件。-1. This procedure has two functions, that is, 6264 randomized read and write 2. To achieve the same port for both output also for input, such as PORTA process as a data input and output port 3. Test Connection documents, see Proteus simulation.

单片机P1口与4个按键连接，用于信号幅度和频率调节操作键。单片机P0、P2.7、P3.6(-WR)与DA0832、2个741(运放)连接构成波形信号输出电路。 编程使波形信号输出电路输出正弦波信号，并且可通过操作键调节信号的幅度和频率。幅度和频率调节级别从0~10，共11个等级。 -Singlechip P1 I connect with the four buttons for the signal amplitude and frequency adjustment operation keys. Singlechip P0, P2.7, P3.6 (-WR) and DA0832, 2 months 741 (operational amplifier) to connect constitute waveform signal output circuit. Programming so that waveform signal output circuit output sine wave signal, and can be operated keys adjust the signal amplitude and frequency. Amplitude and frequency adjustment level from 0 ~ 10, a total of 11 grades.

通过8255查询键值，显示不同的数字。k1显示1，K2显示2，K1和K2显示3,如此类推。最多能显示7。-8,255 inquiries through the keys, show different figures. K1 shows a, K2 showed 2, K1 and K2 showed three, and so forth. The most that can be shown 7.
