C: 10 M: 100 Y: 100 K: 20 MPLAB® PICkitTM 4 In-Circuit Debugger QUICK START GUIDE GETTING STARTED 1 Install the Latest Software Download the MPLAB X IDE software from www.microchip.com/mplabx and install onto your computer. The installer automatically loads the USB drivers. Launch MPLAB X IDE. 2 3 Connect to Target Device 1. Connect the MPLAB PICkit 4 to the computer using the supplied Micro-B USB cable. 2. Attach the communications cable between the debugger and target board. 3. Connect external power to target board. Typical Debugger System – Device with On-Board Debug Circuitry Target Device Power Micro-B USB from computer Target Board Standard Adapter Device-ICE if needed Transition Socket 1. Refer to the MPLAB X IDE User's Guide or online help for instructions to install language tools, create or open a project, and configure project properties. 2. Check that the configuration bits in your code match the Recommended Settings below. 3. To execute your code in Debug mode, perform a debug run. To execute your code in Non-Debug (release) mode, perform a run. To hold a device in Reset after programming, use the Hold in Reset icon in the toolbar.

A simple pull-up resistor is generally sufficient. • Do not use diodes on PGC/PGD: they will prevent bidirectional communication between the debugger and the target device. • Do not exceed recommended cable lengths: Refer to the Hardware Specification of the MPLAB PICkit 4 online help or user's guide for cable lengths.
