[51单片机C语言编程]代码如下： typedef union { unsigned int myvalue; struct{ unsigned myvalueL:8; unsigned myvalueH:8; }child; }_mytype; _mytype mytype; void main() { mytype.myvalue...+阅读

P1=1<

改为这样就可以了

#include #include typedef unsigned int uint16; typedef unsigned char uint8; #define uchar unsigned char uchar temp; void main() { temp=0xfe; while(1) { uint16 i; uint8 j; //---------------------------- P0=temp; temp=_crol_(temp,1); //P0=0xfe<
