我是新手，提問的帖不夠全面，現(xiàn)在完整發(fā)出來，請問一下高手
出錯提示如下：
Error [1250] E:\thermometer\PIC\thermometer.c; 72. could not find space (2 bytes) for variable _SEC
unsigned int SEC;這樣定義編譯會通過，這樣的話比較的數(shù)是不是少于255；理論上是不會的。是不是我哪兒設(shè)置不對？
單片機源程序如下:
#include <pic.h>
//#include "thermometer.h"
unsigned char volatile ADCY_COUNT @ 0X25;
unsigned char volatile DIP0 @ 0X26;
unsigned char volatile DIP1 @ 0X27;
unsigned char volatile WEI @ 0X30;
unsigned char sbstatus @ 0x23;
bit volatile ADCY@((unsigned)&sbstatus*8+0;
unsigned char LED @ 0x21;
bit volatile LEDdp@((unsigned)&LED*8+0;
bit volatile LEDg@((unsigned)&LED*8+1;
bit volatile LEDf@((unsigned)&LED*8+2;
