各位大佬下面這串代碼警告這個是什么意思
*** WARNING L16: UNCALLED SEGMENT, IGNORED FOR OVERLAY PROCESS
未調(diào)用的段，覆蓋過程忽略
SEGMENT: ?PR?MAIM?LCD
段:公關(guān)?致殘?液晶顯示器
*** WARNING L10: CANNOT DETERMINE ROOT SEGMEN
無法確定根段
#include <REGX51.H>#define RS P3_0#define RW P3_1#define E P3_2void delay(unsigned int n){ int i,j; for(i=0;i<n;i++){ for(j=0;j<120;j++); }}void writecom(unsigned int com){ RS=0; RW=0; E=0; P2=com; delay(5); E=1; E=0;}void writedat(unsigned int dat){ RS=1; RW=0; E=0; P2=dat; delay(5); E=1; E=0;}void initlcd(){ writecom(0x38); writecom(0x0c); writecom(0x06); writecom(0x01);}void display(){ writecom(0x80); delay(10); writedat('1'); delay(10);}void maim(){ initlcd(); while(1){ display(); }}
