- #define N 800 其它省略
- sbit KEY = P3^4; //in
- sbit KEY2 = P3^3; //out
- sbit reset = P3^2; //0
- void main()
- {
- uint sumin = 0;
- uint sumout = 0;
- uint in = 0;
- uint out = 0;
- uint arrin[3] = {0,1,2};
- uint arrout[3] = {5,6,7};
- uint i;
-
- for (i = 3;i >= 0; i--)
- {
- arrin[i] = arrin[i] + '0';
- }
- for (i = 3; i >= 0; i--)
- {
- arrout[i] = arrout[i] + '0';
- }
- while(1)
- {
-
- L1602_init();
- L1602_string(1,1,"enter:");
- L1602_string(1,8,"out:");
-
- L1602_string(2,1, arrin);
- L1602_string(2,8, arrout);
- delay_ms(N);
-
- }
- }
- 请问加上for (i = 3;i >= 0; i--)
- {
- arrin[i] = arrin[i] + '0';
- }
- for (i = 3; i >= 0; i--)
- {
- arrout[i] = arrout[i] + '0';
- }就什么都不能输出,删掉就可以,为什么啊,
- 正如这里,我想输出L1602_string(2,1, arrin);
- L1602_string(2,8, arrout);两个数组的值,应该如何修改,不胜感激啊!
- 驱动:void L1602_string(uchar hang,uchar lie,uchar *p)
- {
- uchar a,b=0;
- if(hang == 1) a = 0x80;
- if(hang == 2) a = 0xc0;
- a = a + lie - 1;
- while(1)
- {
- wcmd(a++);
- b++;
- if((*p == '\0')||(b==16)) break;
- wdata(*p);
- p++;
- }
- }
