pickit 3 Description

Microchip’s PICkit3 In-Circuit Debugger/Programmer uses in-circuit debugging logic incorporated into each chip with Flash memory to provide a low-cost hardware debugger and programmer.

The MPLAB PICkit3 allows debugging and programming of PIC® and dsPIC® Flash microcontrollers at a most affordable price point using the powerful graphical user interface of the MPLAB Integrated Development Environment (IDE). The MPLAB PICkit3 is connected to the design engineer’s PC using a full speed USB interface and can be connected to the target via an Microchip debug (RJ-11) connector (compatible with MPLAB ICD 2, MPLAB ICD 3 and MPLAB REAL ICE). The connector uses two device I/O pins and the reset line to implement in-circuit debugging and In-Circuit Serial Programming™.

pickit 3 Basic Debugger System

The debugger system can be configured to use standard ICSP communication for both programming and debugging functions.

CAUTION: Do not change hardware connections while the PICkit3 or target is powered.

Be careful on the pin order while connecting.

Incorrect connection may damage the PICkit3 debugger/programmer or the target board.

PICkit3 Status LEDs

The Status LEDs indicate the status of the PICkit3.

  • Power (green) – Power is supplied to the PICkit3 via the USB port.
  • Active (blue) – The PICkit3 has connection to the PC USB port and the communication link is active.
  • Status:
    Busy (yellow) – The PICkit3 is busy with a function in progress, such as programming.
    Error (red) – The PICkit3 has encountered an error.
