The development system box contains a development system, CD, USB cable andserial cable.

The first thing to do is to take the system out of a box. Unpack the USB cable andconnect 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 dsPICPRO2 board.

The PC will start the procedure for installing the USB driver for the on-board USB2.0 programmer. Follow the procedure from the document ‘ Installing Driver forUSB programmer’ and install the USB driver.

Copy dsPICFLASH.exe file to the folder of your choice. You can find this file inthe dsPICFLASH folder on the CD.

Run and use dsPICFLASH.exe as explained in the document ‘dsPICflash program-mer’.

After these 5 steps, your dsPICPRO2 is installed and ready for use. You should tryto read a program from the chip or to load an example.

Loading an example:

1) Install one of our compilers mikroC for dsPIC, mikroPascal for dsPIC ormikroBasic for dsPIC.2) Open the compiler window and from the Project menu choose Open Project. Inthe compiler’s Examples folder find the dsPIC30F6014 subfolder and open someproject file .3) Build an example (Ctrl+F9) and write .hex file to MCU (F11)

IONThe dsPICPRO2 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. Itallows dsPIC microcontrollers to be interfaced with external circuits and a broadrange of peripheral devices, allowing the user to concentrate on software develop-ment.

Figure 1 illustrates the development board. On a silkscreen, there are identificationmarks beside each component. These marks describe connections to the microcon-troller, operation modes, and provide some useful notes. The need for additionalschematics is minimized as all the information is printed on the board.

S SWITCHES

The dsPICPRO2 development board features many peripherial devices. In order toenable these devices before programming, you need to check if appropriate jumpersor switches have been properly set.

Switches are devices that have two positions - ON and OFF, which have a role toestablish or break a connection between two contacts.

The first switch, SW1, is used to enable LEDs connected to ports RA, RB_L,RB_H, RC/RF, RD_L, RD_H, RF and RG_L. For example, if switch RB_L is OFF,all RB lower LED’s will be turned off.

First switch on SW2 is used for port RG_H. The rest of the switch SW2, SW3 andSW4 are used to enable connections between various peripheral devices and micro-controller pins.

For example, SW2, SW3 and SW4, enable connection between the microcontrollerpins and temperature sensor, programmable gain amplifier (PGA), MMC/SD Card,Compact Flash Card, real time clock (RTC), Digital-to-Analogue Converter (DAC),CAN, CAN-SPI, RS-485 communication etc.

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 pinconnector. As illustrated in Fig. 3, middle connector can be connected to the left orright pin, depending on the jumper’s position.

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

All ports are connected to LEDs, push-button switches and pull-up/down resistors , which allowfor easy digital pin state setting, monitoring and testing.

Some of the pins are connected to other peripherials such as the DS1820 temperature sensor, RS-232 communication, LCD, etc.

As a power supply source, users can select either a regulated supply from USBcable (default) or an external non-regulated power supply.

In case of the USB power supply, the system sholud be connected to a PC using theUSB programming cable and jumper J10 should be set in the right position.

In case of an external power supply, the dsPICPRO2 board produces +5V using anLM7805 voltage regulator. The external power supply can be AC or DC, with avoltage between 8V and 16 V, and jumper J10 should be set in the left position. InFig. 6 you can see the USB (left) and power supply (right) connectors.

Light Emitting Diodes

Each group of eight LEDs can be enabled or disabled using switch SW1 and SW2as shown in Fig. 10.

Fig. 11. on next page illustrates the connection of a LEDs to lower PortB of themicrocontroller. A resistor is used in series with the LED to limit the LED's current.In this case the resistor's value is 1K.

All LEDs from one port are connected to a common point through these resistors,which can then be connected or disconnected to ground by the corresponding switchon SW1. The LEDs are enabled when connected to a ground and will display thestate of the corresponding microcontroller pin; otherwise the LEDs will always beoff, no matter what the pin state is, because no current can flow through it.

In the case of Fig. 16 the pull-down resistor pulls the micro-controller port pin to groundwhen the button is not pressed.A button press causes the portpin to be connected to +5V(J11 is in the upper position).Thus, only when the button ispressed will the microcon-troller sense a logical one; oth-erwise the pin state willalways be logical zero.

In the case of Fig. 15 the pull-up resistor pulls the microcon-troller port pin to +5V whenthe button is not pressed. Abutton press causes the portpin to be connected to ground(J11 is in the lower position).Thus, only when the button ispressed will the microcon-troller sense a logical zero;otherwise the pin state willalways be logical one.

The Graphic LCD (GLCD) allows advanced visual messages to be displayed.While a character LCD can display only alphanumeric characters, a GLCD can beused to display messages in the form of drawings and bitmaps. The most common-ly used graphic LCD has a screen resolution of 128x64 pixels. When you add orremove GLCD be sure that the power supply is off.

GLCD

Figure 17.

Before a GLCD is connected, the user needs toset jumper J19 (Fig. 18) to the upper positionlabeled as GRAPH. The GLCD's contrast canbe adjusted using potentiometer P2.

Note : When used with GLCD the P2 poten-tiometer should start from the Left Position.

DE The standard character LCD is probably the most widely used data visualization

component. Normally, it can display two lines of 16 alphanumeric characters, eachmade up of 5x7 pixels. The character LCD communicates with the microcontrollervia a 4-bit or 8-bit data bus, each requiring the use of a different connector on thedsPICPRO2. For 4-bit data bus use, the LCD should be placed in the upper left ofthe board above the LEDs. The connection to the microcontroller is shown in Fig.22 where there are only four data lines. It is important that the LCD is only addedor removed from the dsPICPRO2 board when the power is off.

When using a character LCD, it should be placed on the GLCD connector. SinceGLCD connector has 20 pins and the character LCD has only 14 pins, special atten-tion is required when placing the LCD. Otherwise the LCD can be permanentlydamaged. The LCD must be placed in the marked position with two free pins to theleft and four free pins to the right. When you add or remove LCD be sure that thepower supply is off.

RS-232 communication enables point-to-point data transfer. It is commonly used indata acquisition applications, for the transfer of data between the microcontrollerand a PC. Since the voltage levels of a microcontroller and PC are not directly com-patible with each other, a level transition buffer such as the MAX232 must be used.

RS232 connectors

dsPICPRO2 development board have two RS-232 communication devices, RS232-A and RS232-B. In order to provide a more flexible system, the microcontroller isconnected to the MAX232 through jumpers. First two jumpers J12 and J13 are usedto connect Rx and Tx lines from microcontroller to RS232-A port, and second twojumpers J14 and J15 for connecting Rx and Tx lines to RS232-B.

Keyboards consist of a large matrix of keys, all of which are monitored by an on-boardprocessor (called the "keyboard encoder".) The specific processor varies from keyboard-to-keyboard but they all basically do the same thing: Monitor which key(s) are beingpressed/released and send the appropriate data to the MCU. This processor takes care ofall the debouncing and buffers any data in its 16-byte buffer, if needed. All communica-tion between the host and the keyboard uses an IBM protocol.

CAN (Controller Area Network) is a serial network that was originally designed forthe automotive industry, but has also become a popular bus in industrial automationas well as other applications. CAN is the network established among microcon-trollers. It is a two-wire, half-duplex, high-speed network system. Half-duplexmeans that microcontroller can send and receive data, but only one way at a time.

dsPICPRO2 development board have eight analogue signal inputs for working withADC. Potentiometer P1 gives analogue signal to microcontroller’s AN8 or AN10analogue inputs. If the J20 jumper is in the upper position then the P1 is connectedto AN8 input. AN8 input can be connected to microcontoller’s RB8 pin directly (J17upper position) or via Programmabile Gain Amplifier PGA1(J17 lower position).

If the J20 jumper is in the lower position then the P1 is connected to AN10 analogueinput. AN10 is connected directly to microcontoller’s RB10 pin. Potentiometer ana-logue output is in the range of 0V to 5V as drawn on the board.

Both PGA integrated circuits (MCP6S22) are connected to microcontroller throughSPI communication and have CS signal (Chip Select). In order to work properly, SPIcommunication must be enabled by setting switches 4 and 6 on SW4 in ON posi-tion (needs only SCK and MOSI because PGA only receives data from microcon-troller - data about amount of gain that will be applied to input signal). Also, PGA-CS1 and PGA-CS2 must be enabled (switches 1 and 2 on SW3). In order to meas-ure an analogue signal without interference, the pull-up/down jumper should beremoved from PORTB high. In this way high pins of PORTB remain floating.

The DS1820 (alternatively DS18B20)digital thermometer is well suited toenvironmental temperature measure-ment, having a temperature range of -55C to 125C and an accuracy of +/-0.5C. It must be placed correctly in the3-pin socket provided on thedsPICPRO2, with its rounded side tothe bottom, as marked on the board.Otherwise the DS1820 could be perma-nently damaged. In order to work,DS1820 must be connected to micro-controller’s RF6 pin, by enablingswitch 3 on SW2.

In many hardware projects there are needs forreal time clock or delay source. Such devicesas clocks, timers, etc. are impossible to prod-uct without knowledge of exact time. RealTime Clock on dsPICPRO2 developmentboard is PCF8583P, and it use I2C serial com-munication to exchange informations withmicrocontroller. Also, it has one interrupt out-put. In order to work properly, both interruptand I2C communication lines must be con-nected to microcontroller by placing switch 6on SW2, and switches 7 and 8 on SW4 in ONposition.

To enableMMC card you must turn on switch 7 on SW2. Also turn on switches 4, 5 and 6 onSW4 to connect microcontrollers’s SPI comunnication lines MOSI, MISO and SCKwith MMC. Working voltage of dsPICPRO2 is 5V DC, while working voltage ofMMC card is 3.3V DC. Because of that, there is a voltage regulator on-board withMMC card (MC33269DT-3.3). Data lines from microcontroller to MMC card mustbe also adjusted to 3.3V. It is done with resister voltage dividers as shown on Figure53.

MMC card is used as storage media for a portable devices, in a form that can easi-ly be removed for access by a PC. For example, a digital camera would use anMMC card for storing image files. With an MMC reader (typically small box thatconnects via USB or some other serial connection) you can easily transfer data fromMMC card to your computer. Microcontroller on dsPICPRO2 communicates withMulti Media Card via SPI communication.

All microcontroller input/output pins can be accessed via connectors placed alongthe right-hand side of the board. For each of the ports PORTA, PORTB low,PORTB high, PORTC, PORTD low, PORTD high, PORTF, PORTG low andPORTG high there is one 10-pin connector providing Vdd, GND and up to eightport pins.

These connectors can be used for system expansion with external boards such asSerial GLCD, IrDA, Ethernet, Toshiba GLCD etc. Ensure that the on-board periph-erials are diconnected from microcontroller by setting the appropriate jumpers orswitches, while external peripherals are using the same pins. The connectors canalso be used for attaching logic probes or other test equipment.
