标题: 封装为一个通用性数码管单片机函数，求指教哦

原理图：


单片机源程序如下:
  1. #ifndef _DEFINE_H_
  2. #define _DEFINE_H_
  3. #include <intrins.h>
  4. //定义数据
  5. unsigned char Seg_Yang_Led_Table[]={0xc0,0xf9,0xa4,0xb0,0x99,0x92,0x82,0xf8,0x80,0x90,0x88,0x83,0xc6,0xa1,0x86,0x8e};
  6. //定义函数
  7. void Delay1ms()  //@11.0592MHz
  8. {
  9. unsigned char i, j;
  10. _nop_();
  11. _nop_();
  12. _nop_();
  13. i = 11;
  14. j = 190;
  15. do
  16. {
  17.   while (--j);
  18. } while (--i);
  19. }
  20. void TestSeg()
  21. {
