hello everyone

Thanks for the overwhelming response that this message board has generated.

I have done tghe fabrication of the PCB. Now the only part remaining is the programming part of the controller.

I am using the keil cross complier which converts the C program directly into a hex file. I have broken down the problem into several small steps.

1. Display all the 81 dots continlusly- I have two arrays of 9 elements each and put them into a continous loop ( problem is that if the controller is in the infinte loop it wont do nething else)

2. I have to move the cursor according to the key pressed by the user and add the line put up by him in the display routine so that it continoulsy shows ( problem cant seem to add the line drawn to the continous loop)

3. Make a winning logic for the microcontroller
