1 Introduction
The PICkit 2 Programmer-To-Go functionality allows a PIC MCU memory image to be downloaded
into the PICkit 2 unit for later programming into a specific PIC MCU. No software or PC is required to
program devices once the PICkit 2 unit is set up for Programming-To-Go. A USB power source for the
PICkit 2 is all that is needed.
Information in this guide covers:
 USB Power for PICkit 2 Programmer-To-Go
 Supported PIC MCU Devices
 Memory Image Size Limitations
 PICkit 2 Programmer-To-Go Wizard Walkthrough
 LED Status Codes

    Example Battery-based Portable USB Power Sources The following two products are shown only for the purpose of illustrating the options available for portable PICkit 2 Programmer-To-Go USB power sources. They are neither specifically endorsed nor recommended by Microchip Technology Inc.
  • Page 3 Figure 2-2 shows the Bluegears b-mobile being used with a PICkit 2 unit for Programmer-To-Go operation. For the curious, the white button turns on a built-in LED flashlight when pressed.

  • Page 5 Large memory parts are supported; what is limited is the size of the program code that can be programmed by PICkit 2 Programmer-To-Go. 2: Device EEPROM data, UserIDs, and Configuration memory are taken into account in these size limitations. For the sake of simplicity, only the Program Memory size determines if the memory image will fit.
  • Page 6 PICkit™ 2 Programmer-To-Go Users Guide Increasing the Memory for PICkit 2 Programmer-To-Go The memory in the PICkit 2 unit available for Programmer-To-Go code storage may be doubled, thus doubling the Program Memory size limitations shown in Table 3-1. To expand the memory it is necessary to replace the two 24LC512 64KB EEPROMs on the PICkit 2 PCB at U3 and U4 with two 24LC1025-I/SM 128KB EEPROMs.
  • Page 7 PICkit 2 Programmer software buffers blank. If Programmer > Verify on Write is checked, then PICkit 2 Programmer-To-Go will verify the device it programs. The PICkit 2 Programmer-To-Go verify is accomplished by calculating a checksum of the programmed device and comparing it with an expected value.
  • Page 8 Once the memory image and programming options for intended target device are set up and tested, start the Programmer-To-Go Setup Wizard via Programmer > PICkit 2 Programmer-To-Go… The wizard dialog will open to the “Welcome” screen. Click Next > to go to the “Programmer Settings”...
