MR. BINU I'm a great fan of your work

I'm asking if you will be kind enough to provide me the source code (.a51, .asm,) for the count down timer, because I remembred that this project counts up instead.Please help me

You can email me regarding the codes onhere

You can download the source code from the projects page.

does the source code from the projects page counts down ? because I read from the post that it counts up. Is that the updated version ? sorry for being annoying, hope you understand

Hi BINU ,can u provide me the report on this project.........................

Mr. Binu, how do i convert the .a51 source code to a .hex source code?
Sorry for being a newb, I really have no idea. The programmer kit which I bought only burns codes in .hex format.
I have the .a51 file and have also downloaded the RIDE program because I've heard it is used for the conversion.
Please send me the detailed process of converting the .a51 file to .hex using RIDE.
Thank you.

1. Create a new project for 8051 microcontroller
2. Create a new file for A51
3. Save the a51 file
4. Add the a51 file to the project
5. Compile the project.
