These are configuration essentials:
- When using the USB connection, MPLAB PICkit 4 can be powered from the
computer but it can only provide a limited amount of current, up to 50 mA, at
VDD from 1.2-5V to a small target board.
- The desired method is for the target to provide VDD since
it can provide a higher current. The additional benefit is that plug-and-play target
detection facility is inherited, for instance, MPLAB X IDE will let you know in the
Output window when it has detected the target and has detected the device.
If you have not already done so, connect the MPLAB PICkit
4 to the target board using the appropriate
cables (see Connecting the Target Board). Then
power the target.
