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.
