Since release of V2.61, PICkit 2 PC software now supports a maximum 4 megabytes of memory for the programmer-to-go feature. These features are missing from the PICkit 3. 256 KB memory can be achieved by modifying the hardware or from third party clones.Īdditionally, a 500 kHz three-channel logic analyser and a UART tool are built into the PICkit 2. The Microchip version of PICkit 2 has a standard 128 KB memory.
The PICkit 2 has a programmer-to-go (PTG) feature, which can download the hex file and programming instructions into on-board memory (128 KB I☬ EEPROM or 256 KB I☬ EEPROM), so that no PC is required at the end application. Linux version of PICkit 2 application software, DOS style CMD support, etc.
End users and third parties can easily modify both the hardware and software for enhanced features. The PICkit 2 is open to the public, including its hardware schematic, firmware source code (in C language) and application programs (in C# language). The latest 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 uses an internal PIC18F2550 with FullSpeed USB.
This feature is not intended for so-called "production" programming, however. This makes it possible to use the programmer with a custom circuit board via an in-circuit serial programming (ICSP) header. The most notable difference between the two is that the PICkit 2 has a separate programmer/debugger unit which plugs into the board carrying the chip to be programmed, whereas the PICkit 1 was a single unit. The PICkit 2 - introduced in May 2005 - replaced the PICkit 1.
