凌阳61板中怎么用72LS164驱动数码管，谁有程序代码发给我一下.

没用过61的，用过51的.
#include <reg51.h>
unsigned char seg_code[]={0x03,0x9f,0x25,0x0d,0x99,0x49,0x41,0x1f,0x01,0x09};

void delayms( unsigned int t )
{
unsigned int m,n;
for( m = 0 ; m < t ; m++ )
for( n = 0 ; n < 100 ; n++ )
{
;
}
}

main()
{
unsigned char i;
while( 1 )
{
for( i = 0 ; i < 10 ; i++ )
{
SBUF = seg_code[i];
while( TI != 1 );
TI = 0;
delayms( 500 );
}
}
}
