360买的双龙M8开发板里CD的程序,正在开发avr板子的学生可以参考一下

extern const unsigned char seg_table[16];
extern unsigned char led_buff[4];
extern void delay_ms(unsigned int time);
extern void display(void);
#define fill_send()  {led_buff[3]=0xbf;led_buff[2]=0xbf;led_buff[1]=0xbf;led_buff[0]=0xb0;}      
#define fill_rece()  {led_buff[3]=0x86;led_buff[2]=0xbf;led_buff[1]=0xbf;led_buff[0]=0xbf;}
#define fill_stop()  {led_buff[3]=0xbf;led_buff[2]=0xbf;led_buff[1]=0xbf;led_buff[0]=0xbf;}
