Hi, my final year project is some kind of an indoor human tracking robot. I decided to use the software ROBOREALM for the webcam. I am using a PIC18F452 microcontroller. The microcontroller interface with RS232. My main problem is interfacing the RS232 with my PC. I did some research and bumped into this website which teach how to communicate rs232 using pic18F452 USART. RS232 Communication using PIC18F4520's USART - PIC Microcontroller Tutorial | eXtreme Electronics. I also install REALTERM to communicate with the PC.
But I keep getting "Build Failed" when i rebuild using MPLAB. I am totally new to this so if anyone can help me, i appreciate alot. Any example codes will also be helpful.
