Typically, a right-angle male connector is used in JP6 so that a PICkit3 can be attached coplanar with
the DP32 board. The connector can be loaded from the top, or it can be loaded from the bottom. In
either case the programmer will be face down (buttons or LEDs not visible).
The Microchip MPLAB®
IDE or the MPLAB® X IDE can be used to program and debug code running
on the DP32 board. These tools can be downloaded from the Microchip website.
Using the Microchip development tools to program the DP32 board will cause the boot loader to be
erased. To use the board with the MPIDE again, it is necessary to program the boot loader back onto
the board. The bootloader image can be downloaded from the DP32 product page on the Digilent
website.
chipKIT DP32 Jumper Settings
JP1
USBID Connect (USB OTG)
Loaded: USBID is connected to Digital I/O pin 0 (RB5) and is usable by the microcontroller.
Unloaded: Pin 0 is unconnected to USBID and freely usable.
JP2
USB Data+
JP3 USB Data-
For most users, these traces should be left uncut. Cutting the trace will remove the ability to program
the microcontroller from the USB Port. Users may optionally add jumper pins and a shorting block to
restore the original functionality of the DP32 if the traces have been cut.
JP4/JP5
Default configuration is with the shorting blocks loaded on pins 1 and 2, which results in pullup
configuration. Shorting pins 2 and 3 results in pulldown operation. Users may choose to remove
shorting blocks entirely if no pullup/pulldown settings are desired.
JP7 Power Select Jumper
Default power select is with the shorting block connecting the two pins directly next to VBUS,
providing power from the USB connector. If external power is desired, connect the two pins nearest
the external power screw terminal labeled VIN.
Power Supply
The DP32 is designed to be powered either via USB or from an external power supply. Only one
supply should be selected at a time.
The DP32 has a single voltage regulator which regulates either 5V from USB to 3.3V, or a maximum
of 15V external voltage to 3.3V. The 3.3V regulator is a Microchip MCP1703. This regulator is rated
for a maximum output current of 250mA. The absolute maximum input voltage for the MCP1703 is
16V. This regulator has internal short circuit protection and thermal protection. It will get noticeably
warm when the current consumed by the VCC3V3 bus is close to the 250mA maximum.
