Getting Started

Development is typically performed using the MPLAB X IDE and the XC8 compiler. Hardware debugging and programming are supported through the In-Circuit Serial Programming (ICSP) interface using tools like the MPLAB PICkit 4 or ICD 4. For rapid prototyping, many engineers use the Curiosity High Pin Count (HPC) Development Board.
