STC89C52單片機(jī)程序中的判斷無效，輸出出現(xiàn)錯(cuò)亂，跪求各位大佬指點(diǎn)
加上“if（i<6）”的判斷時(shí)，按鍵不起作用，不加時(shí)，按鍵起作用，但是OLED上的輸出位置錯(cuò)亂，懇請(qǐng)各位指點(diǎn)
主要單片機(jī)代碼如下：
- #include<reg52.h>
- #include<OLED.h>
- #include<intrins.h>
- sbit b1=P2^0;
- sbit b2=P3^3;
- sbit b3=P2^1;
- sbit b4=P2^2;
- sbit b5=P4^2;
- sbit b6=P4^3;
- sbit bee=P2^4;
- sbit b10=P1^0;
- unsigned int keyword[6];
- unsigned int right_word[6]={1,3,1,4,2,1};
- unsigned int location[6]={10,30,50,70,90,105};
- unsigned int t=0;
- void delay(int ms)
- {
- int ii,jj;
- if (ms<1) ms=1;
- for(ii=0;ii<ms;ii++)
- for(jj=0;jj<500;jj++);
- }
- void start()
- {
- bee=0;
- delay(10);
- OLED_Init();
- OLED_CLS();
- OLED_Fill(0x00);
- OLED_P14x16Ch(25,1,0);
- OLED_P14x16Ch(39,1,1);
- OLED_P14x16Ch(53,1,2);
- OLED_P14x16Ch(67,1,3); //顯示密碼文字//
- OLED_P14x16Ch(81,1,4);
- }
- void beep()
- {
- delay(20);
- bee=1;
- delay(100);
- bee=0;
- }
- void data_input(unsigned int i)
- {
- start();
- while(1)
- {
- if(i<=5)
- {
- if(b1==0)
- {
- delay(20);
- while(!b1);
- beep();
- keyword[i]=1;
- OLED_P6x8Str(location[i],5,"1");
- i++;
- }
-
- if(b5==0)
- {
- delay(20);
- while(!b5);
- beep();
- keyword[i]=2;
- OLED_P6x8Str(location[i],5,"2");
- i++;
- }
-
- if(b2==0)
- {
- delay(20);
- while(!b2);
- beep();
- keyword[i]=3;
- OLED_P6x8Str(location[i],5,"3");
- i++;
- }
-
- if(b6==0)
- {
- delay(20);
- while(!b6);
- beep();
- keyword[i]=4;
- OLED_P6x8Str(location[i],5,"4");
- i++;
- }
- }
- }
- }
- void main()
- {
- data_input(t);
- }
