代码如下
#includevoid main() { int i = 0; unsigned count = 0; unsigned char flag = 0; P0 = 0x01; while(1) { if(flag%2 == 0) { P0 = ~(0x01 << count); } else { P0 = ~(0x80 >> count); } for(i = 0; i < 30000; i++); count++; if(count >= 8) { count = 1; flag++; } }}
代码如下
#includevoid main() { int i = 0; unsigned count = 0; unsigned char flag = 0; P0 = 0x01; while(1) { if(flag%2 == 0) { P0 = ~(0x01 << count); } else { P0 = ~(0x80 >> count); } for(i = 0; i < 30000; i++); count++; if(count >= 8) { count = 1; flag++; } }}
