5 MICROCHIP dspic DEVELOPMENT 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. EASYdsPIC4 development board Figure 1. INTRODUCTION 5

6 SWITCHES 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. Figure 2. Group of 8 switches ON Switch 1 is ON, and other switches are OFF Switch is ON Switch is OFF 6

7 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 pin. A connection is made when the jumpers are placed between two contacts. JUMPERS 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. Figure 4. Jumper as a multiplexer All lines are disconnected Left line is selected Right line is selected 7

8 MCU SOCKETS 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. 8

9 Reset R7 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.

10 POWER SUPPLY POWER SUPPLY SELECTABLE POWER SUPPLY 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. Figure 7. USB and power supply connectors Figure 8.

12 LEDs 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. 12

13 Reset R7 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.

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.

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. Figure 20.

18 RS-232 COMMUNICATION 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, or MCU pin to RX line on RS232 port. Jumper J9 is used to connect RC13, or MCU pin to TX line on RS232 port.. Figure 22. RS232 connector 18

21 ADC INPUT ENABLED 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,, or MCU pin to potentiometer P1. Jumper J7 is used to connect,, 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. ANALOG TO DIGITAL CONVERTER INPUT 21

25 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. PORT EXPANDER For example, if you are using PIC30F4013 you need to select pin for SDO line, pin for SDI line and pin for SCK line. For CS line, you can choose, RB7 or pin. Figure 32.
