PICkit

PICkit is a family of programmers for PIC microcontrollers made by Microchip Technology. They are used to program and debug microcontrollers, as well as program EEPROM. Some models may also feature logic analyzers and serial communications (UART) tools.

The PICkit 1 was a rudimentary USB programmer for PIC microcontrollers, produced by Microchip Technology, the manufacturer of the PIC series of microcontrollers. It was introduced on March 31, 2003, priced at US$36.

The PICkit 1 was integrated into a demonstrator board, featuring eight LEDs, a switch, and a potentiometer. Its default program, explained in the documentation, rotates the LEDs in series. The light display's direction and speed of rotation can be changed with the button and potentiometer on the PICkit board.

The PICkit 2 was introduced in May 2005 to replace the PICkit 1. The PICkit 2 has a separate programmer/debugger unit which plugs into the board carrying the chip to be programmed, whereas the PICkit 1 is a single unit. This makes it possible to use the programmer with a custom circuit board via an in-circuit serial programming (ICSP) header. This feature is not intended for so-called "production" programming, however.

The PICkit 2 uses an internal PIC18F2550 with FullSpeed USB. The PICkit 2 firmware allows the user to program and debug most of the 8 and 16-bit PICmicro and dsPIC members of the Microchip product line.

The PICkit 2 is open to the public, including its hardware schematic, firmware source code (in C language), and application programs (in C# language). End users and third parties can modify both the hardware and software. e.g. Linux version of PICkit 2 application software, DOS-style CMD support, etc.

The PICkit 2 has a Programmer-To-Go (PTG) feature, which enables the PIC MCU memory image to be downloaded into on-board memory (128 KB I²C EEPROM or 256 KB I²C EEPROM). Once the image has been downloaded, devices can be programmed with this memory image without a PC.

The Microchip version of PICkit 2 has 128 KB memory as standard. 256 KB memory can be accommodated by modifying the hardware or by using a third-party clone.
