 Step Two, select “CCS C Compiler for PIC12/14/16/18” from the drop-down list. Click “Next.”
Note: If theplug-in is not listed, make sure that “Show all installed tool suite” is checked. If it
still doesn’t appear, then the CCS Plug-in may not be installed correctly. You will need to reinstall.
 Step Three, type the project name “EX_SQW” and type or select the project directory
“C:\Program Files\PICC\Examples.” Click “Next.”
 Step Four, select file “Ex_SQW.C.“ Click “Add.” Click “Next.”

Start a New Project Manually
#include
#fuses HS, NOLVP, NOWDT, NOPROTECT
#use delay(clock=20000000)
void main() {
int8 a, b, c;
a = 2;
b = 3;

}

c = a + b;
c = a * b;
c = b - a;

 Enter the following program into MPLAB® IDE as “EX8.c” in the “Exercises Directory.”
 Go to Project>New.
 Name the project “EX8” and choose the “Exercises Directory.”
 Click“Add File to the Project” in the “Project” menu and select the “ex8.c” file.
 Click “Select Language Tool Suite” and make sure “CCS C Compiler for PIC12/14/16/18” is
