Chapter 12. Using the dsPIC30F4012

12.1

INTRODUCTION

This chapter assumes you have chosen the dsPIC30F4012 for your application. The

dsPICDEM 2 Development Board supports a dsPIC30F4012 device in a 40-pin PDIP

package, as shown in Figure 12-1. This device provides six 10-bit A/D (500 ksps)

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

sample application program provides a software baseline for building your own

embedded solution.

BOARD SETUP FOR THE dsPIC30F4012 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 dsPIC30F4012 device to

support the dsPIC30F4012 example software in the dsPICDEM 2 Development Kit CD.

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

for the sample application.
