5.5 USING PICKIT 3 PROGRAMMER-TO-GO
To use PICkit 3 Programmer-To-Go to program a target device (when it has been set
up), follow the steps below.
1. Connect a USB power source as discussed in Section 5.2 “USB Power for
PICkit 3 Programmer-To-Go” to the PICkit 3 unit.
2. Ensure the PICkit 3 “Power” LED is lit. The “Active” LED blinks once to indicate
the unit is in Programmer-To-Go mode and ready to program.
3. Connect the PICkit 3 unit ICSP connector to the target. Ensure the target is
powered properly if it is not powering from the PICkit 3.
4. Press the PICkit 3 push button to begin programming.
During the programming operation, the PICkit 3 “Status” LED shows orange and
remains lit while the operation is performed.
When the programming operation has completed, the PICkit 3 unit provides feedback
on the operation via the unit LEDs. A green “Status” LED indicates a successful
operation. Red indicates a programming failure. See Table 5-2 for the feedback codes.

VDD/VPP Error PICkit 3 was unable to set the VDD or VPP
voltage to the expected value.
If PICkit 3 is not providing VDD, then the
error must be a V
PP error.
See (Section 2.5 “Communication Con-
nections”) for VDD and VPP information.

Device ID Error PICkit 3 received an unexpected Device ID
from the target.
Check that the target part matches the one
that was selected when the PICkit 3
Programmer-To-Go was set up. This error
may indicate that a bad ICSP connection is
preventing the PICkit 3 from communicating
with the target. Not applicable to Baseline
devices.
Off Red
3 blinks in
succession:

Verify Error The target did not Verify successfully after
programming.
Ensure the target VDD meets the minimum
required. With Baseline devices, this error
may indicate ICSP communication
problems.

Internal Error An unexpected internal Programmer-To-Go
error occurred.
If it happens a second time, try
downloading to the PICkit 3 again.
Note: Press the PICkit 3 pushbutton to clear the error code and initiate a new
programming operation.
