Chapter 5. Using the dsPIC30F2012

5.1

INTRODUCTION

This chapter assumes you have chosen the dsPIC30F2012 for your application. The

dsPICDEM 2 Development Board supports a dsPIC30F2012 device in an 28-pin,

SPDIP package, as shown in Figure 5-1. This device provides ten 12-bit A/D (100 ksps)

channels, a UART, an SPI module, an I2C module and 20 I/O pins. A sample applica-

tion program provides a software baseline for building your own embedded solution.

BOARD SETUP FOR THE dsPIC30F2012 SAMPLE APPLICATION

The dsPICDEM 2 Development Board supports dsPIC30F devices that have multiple

peripheral devices multiplexed on some pins. Therefore, the jumper set up of various

headers depends on which of the dsPIC30F peripherals are used by the application.

This section demonstrates how the board is set up for the dsPIC30F2012 device to

support the dsPIC30F2012 example software in the dsPICDEM 2 Development Kit CD.

Follow these steps to configure the hardware on the dsPICDEM 2 Development Board.

Disconnect the power source.

Remove any dsPIC30Fxxxx device currently plugged into the dsPICDEM 2

Development Board.

Plug the dsPIC30F2012 into socket U1B1.

Configure the hardware components as shown in Table 5-1.
