Few of us here use C. Being BASIC code is a "readable" code you should be able to follow it even if you do not use BASIC.

I will assume you know C or are learning C so you should be able to get it going by reading through the BASIC code.

Maybe for help with the C part?

If you have specific questions we are glad to help if we can. But when someone ask for the work to be done for them... that does not go over very well.

Good Luck.
