PICkit

PICkit is a family of inexpensive in-circuit programming and debugging tools produced by Microchip Technology for PIC microcontrollers. These devices provide a practical means to program and erase PIC devices through the In-Circuit Serial Programming (ICSP) interface and are commonly used in education, hobbyist projects, and development workflows.

Physically, the programmer connects to a PC via USB and to the target microcontroller through a 6-pin ICSP header carrying Vdd, Vss, PGC, PGD, and MCLR signals. Most PICkit models can power the target from the USB supply or accept external power, and they typically monitor Vdd during programming to ensure proper operation.

Software support and workflow are centered on Microchip’s tools. PICkit devices are supported by MPLAB X IDE and the older standalone PICkit software for older models. Users can perform operations such as erasing device memory, programming flash and configuration bits, reading device IDs, and, on supported configurations, debugging with MPLAB X when the device is connected.

Models and scope: The PICkit line has included PICkit 1, PICkit 2, PICkit 3, and PICkit 4, with newer revisions focusing on faster programming and improved power management. Device support varies by model and firmware, covering a broad range of Microchip PIC16, PIC18, PIC24, and dsPIC families. The PICkit tools are widely used for learning, rapid prototyping, and non-production programming, and they complement higher-end debugging and programming instruments.

Limitations and context: While cost-effective and user-friendly, PICkit devices are generally less feature-rich than professional emulators and programmers. Some of the newest devices or chips may require updated firmware or software, and compatibility should be checked for specific PIC devices and IDE versions.
