thanks robosang. i really appreciate it. For ur info actually i have no basic in c programming. I learn for the previous program and try it to the new board. So i'm try in error. This is the first time i'm doing the programming on robot because have been selected in robocon team in my work place. Thanks alot.
Understand that, but my advise is to understand the concept, you cannot keep copy only, I think the previous code from the old board is also copy from some place, right? I do not blame you, but you need to take the initiative to learn.
