dsPICDEM™ 2 DEVELOPMENT BOARD LAYOUT

1.4.2

MPLAB ICD 2 Header

An RJ11 connector (J1) allows the MPLAB ICD 2 Debugger/Programmer to be used

with the dsPIC30F device you have plugged into the board. Switches S2, S3 and S4

physically connect this interface to the device sockets. Switch S2 connects the MPLAB

ICD 2 interface to the default programming and debugging pins on the dsPIC30F

devices (PGC/EMUC and PGD/EMUD). This switch should be turned on during

programming.

Switches S3 and S4 connect the MPLAB ICD 2 interface to alternative debugging pins

on the dsPIC30F devices (EMUC1/EMUD1 and EMUC2/EMUD2). These switches

should be turned off during device programming and turned on during debugging, if

needed.

1.4.3

UART Connection

A DB9 connector (J2) facilitates external RS-232RS-232 communication. Headers H3,

H4 and H5 connect this interface to the UART peripheral in the dsPIC DSC device.

Header H3 selects UART1. Header H4 selects alternate pins for UART1 in all

dsPIC30F devices supported by this board. Header H5 selects UART2 in dsPIC30F

devices that provide two UARTs (dsPIC30F3011, 3013, 3014, 4011 and 4013).

1.4.4

CAN Connection

A second DB9 connector (J3) is used for CAN communication. Header H2 selects the

dsPIC DSC device for the CAN interface. The CAN interface is supported by

dsPIC30F4011, 4012 and 4013 devices.

1.4.5

Power Supply

The dsPICDEM™ 2 power supply IS powered from an AC/DC wall adapter that

furnishes 9 VDC to the PWR jack (J4). The power supply is split at the regulator to

provide a separate, de-coupled analog supply voltage useful in designs taking

advantage of the dsPIC30F A/D converters. The power supply includes an on-board

+5V regulator for supplying VDD and AVDD. An LED indicates when the power is on.

Jumpers (JP1 and JP2) let you disconnect the power supply from the board if you want

to supply external DC power via terminals TP1 and TP2.
