Hello all,

I am trying to program Blinky program from Keil complier to P89LPC936 microcontroller through a universal programmer(SuperPro). But the microcontroller is not running. But when i write a simple program in assambly and program the same hardware it works fine. Please I need help regarding it where i am doing wrong.

Here is code >>>
Code:
/* Blinky.C - LED Flasher for the Keil LPC900 EPM Emulator/Programmer Module */

#include <REG936.H> // register definition

void delay (unsigned long cnt)
{
while (--cnt);
}

void main()
{
unsigned char i;

P1M1 |= 0x20;
P1M2 &= 0xDF;

P2M1 &= 0xE7;
P2M2 |= 0x18;

delay (20000);
for(;;)
{ for (i = 0x01; i; i <<= 1)
{ P2 = i; // simulate running lights
delay (20000);
}
for (i = 0x80; i; i >>= 1)
{ P2 = i;
delay (20000);
}
}
}
Here is Hex file >>>

And here is the assembly code and its hex file which is working absolutely right.

Code:

And its hex is
