Reaction timer pbp project help needed

[sphinxifm]

i am building a project that consists of two buttons connected to a pic 16f877a that needs to have a time delay and at the end of the delay a light comes on and the button has to be pressed, the first to press their button is the winner and their led lights for 30 seconds and then goes off but the time delay needs to be a random time between 2 and 10 seconds each time the game is played. (ie not the same time delay every time) could anyone help with this problem as i have been searching through the forums but am unable to find any code for pbp that can help. i have built the circuit and can place the led's and buttons on any port. i will post all details of the project as soon as its completed. many thanks in advance for all/any help.

[sphinxifm]

Thankyou for your offer to help. I have a very limited knowlage of assembly but would appreciate any help/code you could offer. Is it possible that i could use your code and call it from a program i write in pbp? any help is greatly appreciated.

Hmmm...sounds like a class project to me...anyway, it's quite a simple program...what are you having trouble with exactly?

Hi

It might be of help to you. i think that you can include assembly language within the basic.
Hope this helps
