Hi!
I also tried Asim Khan's software but it never worked for me. The software that i have uploaded is configurable. You probably won't have to change your hardware.

Hi!
Although i haven't got much experience with 8051's and their programming but i can be in a better position if you can post the schematic of the hardware that you are using. May be the usb speed is more than fast for the programmer to work correctly.
Regards.

89s51 programmer asim khan

Hi!
I have attached an image that shows the setting of the software that i have loaded for your programmer.
You should also correctly specify your processor board clock frequency correctly.
Regards.

hi waseem
Thanx 4 ur consistant replies.
i've few doubts about wat u've sent.
1)how u've set port address in hex,i've tried this many times but wont work 4 me.
2)the pin configuration u've set is different from my circuit diagram.should i change my circuit diagram accordingly?
If possible could u please send me the detailed circuit diagram,it will be very useful.


Regards
Rushikesh
 

time is short asim khan

Hi Rushikesh!
You are welcome.
1. I haven't set the port address myself, the sofware automatically detects the
ports available. You can only select one of the ports shown by the software.
2. I have configured the pins according to the programmer image that you have
loaded in your previous message.
3. I have attached the hardware schematic of the programmer that i had used with
this software.
4. If possible view the outputs on the port pins using an oscilloscope and verify
wheather they are changing their levels.
5. Another important thing is the length of the programming cable. For initial
testing keep it as short as possible.

Regards.
