CONNECTING TTHE SSYSTEM

The development system box contains a development system, CD, USB cable and

serial cable.

The first thing to do is to take the system out of a box. Unpack the USB cable and

connect it to the PC. Please use USB ports from the back of the PC, with direct con-

tact to the motherboard.

Connect the USB cable to the dsPICPRO board.

The PC will start the procedure for installing the USB driver for the on-board USB

2.0 programmer. Follow the procedure from the document ‘ Installing Driver for

USB programmer’ and install the USB driver.

Copy dsPICFLASH2.exe file to the folder of your choice. You can find this file in

the dsPICFLASH folder on the CD.

Run and use dsPICFLASH2.exe as explained in the document ‘dsPICflash pro-

grammer’.

After these 5 steps, your dsPICPRO is installed and ready for use. You should try

to read a program from the chip or to load an example from the examples folder.

INTRODUCTION

The dsPICPRO development system is a full-featured development board for

Microchip dsPIC microcontrollers. It has been designed to allow students and engi-

neers to easily exercise and explore the capabilities of dsPIC microcontrollers. It

allows dsPIC microcontrollers to be interfaced with external circuits and a broad

range of peripheral devices, allowing the user to concentrate on software develop-

ment.

Figure 1 illustrates the development board. On a silkscreen, there are identification

marks beside each component. These marks describe connections to the microcon-

troller, operation modes, and provide some useful notes. The need for additional

schematics is minimized as all the information is printed on the board.

SWITCHES

The dsPICPRO development board features many peripherial devices. In order to

enable these devices before programming, you need to check if appropriate jumpers

or switches have been properly set.

Switches are devices that have two positions - ON and OFF, which have a role to

establish or break a connection between two contacts.

The first switch, SW1, is used to enable LEDs connected to ports RB_L, RB_H,

RD_L, RD_H, RF and RG. For example, if switch RB_L is OFF, all RB lower

LED’s will be turned off.

The switches SW2 and SW3 are used to enable connections between various

peripheral devices and microcontroller pins.

For example, SW2 and SW3, enables a connection between the microcontroller

pins and temperature sensor, programmable gain amplifier (PGA), real time clock

(RTC), RS-485 communication etc.

JUMPERS

Jumpers, like switches, can break or establish a connection between two points.

Beneath the plastic cover of the jumper is a metal contact, which makes a connec-

tion when the jumper is placed between two disconnected pins.

Jumpers are used as a selector between two possible connections using a three pin

connector. As illustrated in Fig. 3, middle connector can be connected to the left or

right pin, depending on the jumper’s position.

All lines are disconneced

When you are placing MCU Card on the dsPICPRO MCU socket you must follow

these steps:

MCU CCARD

If there is already MCU Card

placed on dsPICPRO, you must

remove it by slowly pulling it up.

Label on the MCU Card must

be at the upper-left corner as it

is drawn on the dsPICPRO

board.

When MCU Card is on the place,

push it down by applying the

pressure on all edges at the same

time.

The microcontroller’s pins are routed to various peripherials as illustrated in Fig.5. All ports have

direct connections to Direct Port Access connectors. Such connectors are typically used for con-

necting external peripherials to the board, or for providing useful points for connecting digital

logic probes.

All ports are connected to LEDs, push-button switches and pull-up/down resistors , which allow

for easy digital pin state monitoring and testing.

Some of the pins are connected to other peripherials such as the DS1820 temperature sensor, RS-

232 communication, LCD, etc.
