This is a Getting Started with MPLAB X IDE and XC8 compiler tutorial. MPLAB® X IDE is the new Microchip IDE and it runs on a PC with Windows®, Mac OS® or Linux® to develop applications for PIC microcontrollers and replaces all MPLAB® C and HI-TECH compilers. XC8 is the new C compiler for PIC10, PIC12, PIC14, PIC16 and PIC18 microcontrollers. Learn how to start a new project with MPLAB X IDE, configure your PIC fuses and oscillator, write a simple Blink LED code and simulate the code with Proteus.
