thanks a lot for the early replies..helo..i have tried the code on keil..but it shows only one update on port i.e. 0x01; after that it shows nothing on the ports..pls help me out how can i refine the code to show the updates....


#include <AT89X52.h>

#define NUMPAT 8
#define NUMIN 2
//double Input[NUMPAT+1][NUMIN+1] = { 0, 0, 0, 0, 0, 0, 0, 1, 0, 0, 0, 1,0, 1, 1 };
double Input[NUMPAT+1][NUMIN+1] = { 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12,13, 14, 15 };

void main (void)
{
unsigned char i,j;

for (i=0; i<NUMPAT+1; i++)
{
for (j=0; j<NUMIN+1; j++)
P1= Input[i][j];
}
}
