数字音乐盒
(1) 硬件电路中用P1.0~P1.7控制按键,其中P1.0~P1.3扫描行,P1.4~P1.7扫描列。
(2) 用P0.0~P0.7,P2.0~P2.7控制LED,其中P0.0~P0.7控制七段码a,b,c,d,e,f,g,用P2.0~P2.7为数码管位选信号。
(3) 用,P2.0~P2.2作为LCD的RS,R/W,E的控制信号。用P0.0~P0.7作为LCD的D0~D7的控制信号。
(4) 用P3.7口控制蜂鸣器(J2,J4断开,J3短接)。
(5) 电路为12MHZ晶振频率工作,起振电路中C1,C2均为30pf。-Digital Music Box (1) hardware circuits using P1.0 ~ P1.7 control button, which P1.0 ~ P1.3 scan lines, P1.4 ~ P1.7 scan out. (2) by P0.0 ~ P0.7, P2.0 ~ P2.7 control LED, of which P0.0 ~ P0.7 Control Code paragraph a, b, c, d, e, f, g, with P2 .0 ~ P2.7 as a digital control bit selection signal. (3), P2.0 ~ P2.2 as the LCD of the RS, R/W, E of the control signal. P0.0 ~ P0.7 used as the LCD of the D0 ~ D7 of the control signal. (4) by P3.7 buzzer population control (J2, J4 disconnect, J3 shorted). (5) circuit for the crystal frequency of 12Mhz work, start-up circuit C1, C2 are 30pf.
