关于按键的讨论

2019-07-15 16:47发布

各位走过路过的大神OR初学者，小弟刚接触单片机，现在想编写一个程序实现这样的功能：开关（SwitchH）按下，通道1（CHAN1）通路，按下一个（DOWN_BUTTON）通道2（CHAN2）通路，以此类推。如下代码请各位看看错在哪里：
#include<reg52.h>
typedef unsigned char u8;
typedef unsigned int u16;
sbit CHAN1 = P0^0;
sbit CHAN2 = P0^1;
sbit CHAN3 = P0^2;
sbit CHAN4 = P0^3;
sbit CHAN5 = P0^4;
sbit CHAN6 = P0^5;
sbit CHAN7 = P0^6;
sbit CHAN8 = P0^7;
sbit CHAN9 = P2^0;
sbit CHAN10 = P2^1;
sbit SwitchH = P1^5;
sbit UP_BUTTON = P1^6;
sbit DOWN_BUTTON = P1^7;

void dealy(unsigned int y)
      {
unsigned int x,z;
for(x = y;x > 0;x--)
for(z = 110;z > 0;z--);
      }

void main()
      {
      CHAN1 = 1;
      CHAN2 = 1;
      CHAN3 = 1;
      CHAN4 = 1;
      CHAN5 = 1;
      CHAN6 = 1;
      CHAN7 = 1;
      CHAN8 = 1;
      CHAN9 = 1;
      CHAN10 = 1;
      SwitchH = 1;
      UP_BUTTON = 1;
      DOWN_BUTTON = 1;
      while(1)
            {
            dealy(10);
            if (SwitchH == 0)
                     {
                     CHAN1 = 0;
                     }
            if (CHAN1 == 0)
                     {
                     if (DOWN_BUTTON == 0)
                              {
                              CHAN1 = 1;
                              CHAN2 = 0;
                              }
                     if (SwitchH == 0)
                              {
                              CHAN1 = 1;
                              }
                     }
