BOARD
INTRODUCTION
The EASYdsPIC4 development system is a full-featured development board for Microchip
dsPIC microcontrollers. It has been designed to allow students and engineers 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 development.
Figure 1 illustrates the development board. On a silkscreen, there are identification marks
next to each component. These marks describe connections to the microcontroller, operation
modes and provide other useful notes. The need for additional schematics is minimized as
all relevant information is printed on the board.

SWITCHES
The EASYdsPIC4 development board features a number of 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 EASYdsPIC4 development board has two
groups of switches.
The upper four switches of SW1 are used to enable LEDs connected to PORTB/C,
PORTA/D, PORTE and PORTF. For example, if the switch for PORTB is OFF, all PORTB
LEDs will be turned off. Switches 5 and 6 of SW1 are used to enable SDO(Serial Data Output) and switches 7 and 8 to enable SDI (Serial Data Input).
The first two switches of SW2 are used to enable SCK, switches 3, 4 and 5 are used for
enabling CS (Chip Select) lines. Witches 7 and 8 are used to enable LCD Backlight and
GLCD Backight respectively.

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 connection if the jumper is
placed between two disconnected pins.
For example, jumper J16 is used as switch. It is used to connect the 4.096V voltage reference to the microcontroller’s RB0 pin. A connection is made when the jumpers are placed
between two contacts.
Figure 3.
Jumper as a switch
Jumper is ON
Jumper is OFF
More often jumpers are used as a selector between two possible connections by using a three
pin connector. As illustrated in Fig. 4, the middle contact can be connected to the left or right
pin, depending on the jumper’s position.

MCU SOCKETS
EASYdsPIC4 is delivered with a PIC30F4013, 40-pin microcontroller. Users can remove
this one and fit a different microcontroller in DIP40, DIP28, DIP28, DIP18 packages. There
are two different sockets for 40-pin MCUs (DIP40A and DIP40B). There are also two sockets for 28-pin MCUs (DIP28A and DIP28B).
For example,PIC30F4013 should be placed in DIP40B socket and PIC30F4011 should be
placed in DIP40A socket.
Figure 5.
MCU sockets
Note: Since all packages have parallel connections, there must not be more than one microcontroller on the board at a time.
Note: If you use DIP28A, DIP40A, or DIP40B MCU socket, use OSC1 oscillator socket. If
you use DIP28B or DIP18 MCU socket, use OSC2 oscillator socket.

Microcontroller’s pins are routed to various peripherals as illustrated in Fig. 6. All ports have
direct connections to Direct Port Access connectors. Such connectors are typically used for
connecting external peripherals to the board or for providing useful points for connecting
digital logic probe.
All ports are connected to LEDs, push-button switches and pull-up/down resistors, which
allow easy monitoring and testing of digital pin state .

SELECTABLE
As a power supply source, users can select either a regulated supply from the USB cable
(default) or an external power supply. In case of the USB power supply, the system should
be connected to a PC using the USB programming cable, while the jumper J12 should be
set in the right-hand position.
In the case of an external power supply, the EASYdsPIC4 board produces +5V using an
LM7805 voltage regulator. The external power supply can be AC or DC, with a voltage
between 8V and 16V and the jumper J12 should be set in the left-hand position. In Fig. 7
you can see USB and external power supply connectors.

LEDs
Light Emitting Diodes (LEDs) are the most commonly used components, usually for displaying pin’s digital state. EASYdsPIC4 has 36 LEDs that are connected to the microcontroller’s PORTB, PORTC, PORTD, PORTE and PORTF.
Figure 12. Light Emitting Diodes
Each group of LEDs can be enabled or disabled using the switch SW1. The first switch
enables LEDs on PORTB and PORTC, the second switch enables LEDs on PORTA and
PORTD. Switches 3 an 4 are used to enable LEDs connected to PORTE and PORTF respectively.
Fig. 13. illustrates the connection of a LEDs connected to PORTB of the microcontroller. A
resistor is used in series with the LED to limit the LED's current. In this case the resistor's
value is 1K.

The LEDs are enabled when the corresponding switch on SW1 is on. When enabled, LEDs
will display the state of the corresponding microcontroller pin; otherwise the LEDs will
always be off, no matter what the port state is, as no current can flow through LED.

Buttons connections to PORTA, PORTB, PORTC, PORTD, PORTE and PORTF are shown
in Fig. 17. Jumper J15 determines whether a button press will bring logical zero or logical
one to the appropriate pin.
When button is not pressed, pin state is determined by the pull-up or pull-down port
jumpers.
In the example shown in Fig. 17, J15 is connected to +5V, therefore pressing the buttons will
bring logical one to the appropriate pins.

The standard character LCD is probably the most widely used data visualization component. Usually, it can display two lines of 16 alphanumeric characters, each character made
up of 5x8 pixels. The character LCD communicates with the microcontroller via a 4-bit data
bus. The connection to the microcontroller is shown in Fig. 21 where there are only four
data lines. It is important that the LCD is only inserted or removed from the EASYdsPIC4
when the power is off. Potentiomenter P4 is used to adjust the LCD’s contrast and switch 7
of switch group SW2 is used to turn on or off the LCD’s backlight.

RS-232 COMMUNICATION
RS-232 communication enables point-to-point data transfer. It is commonly used in data
acquisition applications, for the transfer of data between the microcontroller and a PC. Since
the voltage levels of a microcontroller and PC are not directly compatible with each other,
a level transition buffer such as the MAX232 must be used.
There are two jumper groups J8 and J9 for connecting MCU lines to MAX232 tranciever.
Jumper J8 is used to connect RC14, RF2 or RF4 MCU pin to RX line on RS232 port .
Jumper J9 is used to connect RC13, RF3 or RF5 MCU pin to TX line on RS232 port..

EASYdsPIC4 User’s Manual
A/D CONVERTER INPUT
EASYdsPIC4 development board has two potentiometers for working with Analog to
Digital Converter (ADC). Both potentiometers outputs are in the range of 0V to 5V. Two
analog signals can be connected on two different analog input pins at the same time. There
are two jumper groups J6 and J7 for connecting MCU lines to potentiometers P1 and P2.
Jumper J6 is used to connect RB0, RB1, RB2 or RB3 MCU pin to potentiometer P1. Jumper
J7 is used to connect RB4, RB5, RB6 or RB7 MCU pin to potentiometer P2.
Figure 27. A-D Converter input
In order to measure analog signal without interference, turn the coresponding switch on
SW1 to OFF position. This will disable connection from the used PORTB pin to the pullup/down resistors.
Applications of A-D Conversion are various. Microcontroller takes analog signal from its
input pin and translates it into a digital value. Basically, you can measure any analog signal
that fits in range acceptable by dsPIC. That range is 0V to 5V.

DIRECT PORT ACCESS
All microcontroller input/output pins can be accessed via connectors placed along the right
side of the board. Each port (PORTA, PORTB, PORTC, PORTD, PORTE and PORTF) can
be accessed via 10-pin connector (IDC10) providing VCC and GND.
Direct port access connectors Figure 29.
These connectors can be used for system expansion with external boards such as Serial
Ethernet, Compact Flash, MMC/SD, ADC, DAC, CAN, RTC, RS-485, etc. Ensure that the
on-board peripherals are disconnected from microcontroller by setting the appropriate
jumpers, while external peripherals are using the same pins. The connectors can also be used
for attaching logic probes or other test equipment.

PORT EXPANDER
The MCP23S17 device family provides 16-bit, general purpose parallel I/O exopansion for
SPI applications.
The MCP23S17 consists of multiple 8-bit configuration registers for input, output and polarity selection. The system master can enable the I/O as either inputs or outputs by writing the
I/O configuration bits. The data for each input or output is kept in the corresponding input
or output register. The polarity of the Input Port register can be inverted with Polarity
Inversion register. All registers can be read by the system master.
In order to enable SPI communication you need to select source pins for SDO, SDI, SCK
and CS lines, depending on MCU you are using.
For example, if you are using PIC30F4013 you need to select RF3 pin for SDO line, RF2
pin for SDI line and RF6 pin for SCK line. For CS line, you can choose RB5, RB7 or RB8
pin.
