How to program the PIC

Open folder mpasmx

Create a new folder called ME475 (Here you are going to save all your
projects).

Remember to save your program file as, example.asm (do not use
spaces and try to use short names)
17

Open MPASMX
18

Select program.asm file
19

Click on Assemble.
20

You have generated a .HEX file (example.hex) which is the file to be
load into the PIC
21
Downloading the program

Connect the car to the computer, and set the program switch on PRG
22

Open the software B77-TB
23

Erase previous program and load the file.HEX
24

Program the PIC
25
Running the program on the PIC

Turn the Program switch to RUN, and push the RED button.
