Web1、控制蜂鸣器. Y5C通过一个锁存器，在P0口对应位输出，可以看到第七位对应BUZZ . 而Y5C又由Y5与WR（默认通过跳线帽接地）通过或非门得来， P2口的高3位通过38译码器来控制Yx（x表示0~7）输出，所以，相应控制代码如下： u8 bdata port; sbit buzeer = port^6;void Buzeer(u8 s) {buzeer = s;P0 = port;P2 = 0xa0; //P2=0xa0，表示 ... WebMay 16, 2012 · SBIT( P0_4 , 0x84 ) /* GPIO - Port 0, Input 4 */ SBIT( P0_3 , 0x83 ) /* GPIO - Port 0, Input 3 */ ... Thanks for putting me straight. I got my books out (again) and realised that the #define just replaces SBIT with the new definition, using the parameters it is passed. Thanks again - Jim Pinder.
