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.

6段数码管分别显示，时，分，秒，四个按键，K1（P0.0），K2（P0.1）， K3（P0.2），K4（P0.3），四个按键用来调时间的，按下K1，所有位都清零显示，然后按下K2，秒在闪烁，继续按K2分闪烁，不段地按K2 秒--分--时切换着闪烁，在某位闪时按下K3相应位加一，确认调整，按K4，取消调整再按K1。在K1按下以后才有调时的功能，如果K1没有按下，按别的键没有反映。这为了在加点按键功能留着用 -6 respectively of the digital control, when, minutes and seconds, four keys, K1 (P0.0). K2 (P0.1), K3 (P0.2), K4 (width), the four keys to the transfer time, press the K1, All spaces are reset, then press K2, the scintillation seconds, according to K2 pm flickered. not according to K2 of seconds-- minutes-- when switching to flicker in certain press the flash-K3 corresponding increase in a confirmed adjustment by K4, then canceled K1 adjustment. K1 in the press will only be made after the transfer of function, if K1 pressed by other key is not reflected. This points to the function keys used Retention
