PICkit™2 Programmer: Getting Started

PICkit2 Programmer is a low cost MPLAB Compatible PIC programmer. When connected, the MPLAB IDE detects it automatically. It can program PIC controllers operating at 3V3 and 5V.

The PICkit2 Development Programmer/Debugger, a full featured Windows programming interface, supports baseline (PIC10F, PIC12F5xx, PIC16F5xx), mid rang (PIC12F6xx, PIC16F) ,PIC18F, PIC24, dsPIC30, dsPIC33,and PIC32 families of 8-bit, 16-bit, and 32-bit microcontrollers, and many Microchip Serial EEPROM products. With Microchip’s powerful MPLAB IDE (Integrated Development Environment), the PICkit 2 enables in-circuit debugging on most PIC microcontrollers. In-Circuit-Debugging runs and halts the program on break points while the PIC microcontroller is embedded in the application. When halted at a breakpoint, the file registers can be examined and modified. Using pickit2, we can use about 95% of the controller memory. If we use boot-loader to program, then we will have to reserve separate memory just to fuse boot-loader.

LayoutGetting Started

The PIC Programmer uses a USB port, for both powering  and connecting to the computer, as opposed to the traditional serial port, eliminating the need for a separate power supply. It will automatically power the circuit, if the target controller is not powered. The programmer can be used to program 3.3V and 5V micro controllers. Automatic selection of voltage level is one of the unique features of this programmer.

PIN Description

  • TARGET   : The PIC Programmer Lite is powering the target device
  • PWR         : Power is applied to the PIC Programmer Lite via the USB port
  • BUSY        : The PIC Programmer Lite is busy with a function in progress, such as programming
