p89LPC936 programming through universal programming,

[dani]

Hello all,

I am trying to program Blinky program to P89LPC936 microcontroller through a universal programmer(SuperPro). But the microcontroller is not running. Please I need help regarding it where i am doing wrong.

Here is code >>>

/* Blinky.C - LED Flasher for the Keil LPC900 EPM Emulator/Programmer Module */

#include <REG936.H> // register definition

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

void main()
{
unsigned char i;

P2M1 = 0;

for(;
{ for (i = 0x01; i; i <<= 1)
{ P2 = i; // simulate running lights
delay (50000);
}
for (i = 0x80; i; i >>= 1)
{ P2 = i;
delay (50000);
}
}
}

Here is Hex file >>>

:10000300E4F5A47D01ED600EF5A07F507EC31138A9

:00000001FF

And here is the Dev Config attached settings in SuperPro universal programmer >>>

Hi Dani,

I do not understand what exactly u r trying to say.
But looking at ur code, ur port pin is not configured properly (P2M1 = 0.
It should be in the following manner(by the combination of M1 & M2). Also refer the datasheet for the same. its quite simple.

PXM1 0|
|---- QUASI BIDIRECTIONAL.
PXM2 0|


PXM1 0|
|---- PUSH PULL MODE.
PXM2 1|



PXM1 1|
|---- INPUT ONLY.(HIGH IMPEDENCE).
PXM2 0|


PXM1 1|
|---- OPEN DRAIN MODE.
PXM2 1|


regards
mandar

Dear mandar,

Thanks for replying, The microcontroller seems to be stuck and don't work at all, Thats what i was trying to say. I tried the port and pin configuration but it is not working. Any clue why...

R programming settings i.e. dev config are ok...

 

[mandar_mahajan]

You r using Port 2, right???
your port 2 pins must be in PUSH PULL MODE OR QUASI BI DIRECTIONAL MODE.
What's the voltage u r getting on ur portpins when u want to glow the LED'S. There might be a problem in ur hardware also.

I use Flash Magic for loading the program in my LPC. Don't have any idea for dev config .
Portpin config should be as below:

P2M1 = 0x00; // Quasi
P2M2 = 0x00;

OR

P2M1 = 0x00; // Pushpull
P2M2 = 0xff;

I have tried this way as well but of no use.. here i am going to attach the project of keil with source files. I think i may be doing some wrong or incomplete steps which is not resulting in correct hex file. Please mandar, and other kindly help me.

Hello Dani,
It seems u r missing some basics. Any microcontroller code runs in a infinite while loop.
Plz try the below code.

void delay (unsigned long cnt);

void main()
{
unsigned char i;

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

P2M1 = 0x00; // Pushpull
P2M2 = 0xff;

while(1)
{
delay (20000);
P2 = 0x00;
delay (20000);
P2 = 0xff;
}

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

Hi,
may be I just missed the entry in the list but I could not find the information that Xeltek Superpros supports the LPC900 series. And if it does not, there is no way it could work.
hth, Bob

You mean , entry from the startup .s file in the code, Yes it may be the problem you are right. But how to correct it. I have used default startup file coming with keil.

Super pro programmer does support lpc900 series i have infect checked it using a simple assambly program below and it is working fine with this.
