75SEGMENT

One seven segment digit consist of 7+1 LEDs which are arranged in a specific formation which can be used to

represent digits from 0 to 9 and even some letters. One additional LED is used for marking the decimal dot, in

case you want to write a decimal point in the desired segment. The easyPIC540 contains six of these digits put

together to form 65digit 75segment display. Driving such a display is done using multiplexing techniques. Data

lines are shared between segments, and therefore the same segment LEDs in each digit are connected in parallel.

Each digit has it’s unique digit select line, which is used to enable the digit to which the data is currently being

sent. By multiplexing data through all six segments fast enough, you create an illusion that all six segments are in

operation simultaneously. This is possible because human eye has a slower reaction time than the mention changes.

This way you can represent numbers in decimal or hexadecimal form. Eight data lines that are common for all the

digits are connected to PORTD, and digit select lines are connected to RA0– RA5 lines on the microcontroller

sockets.

To enable digit select lines for the 65digit 75segment display you have to turn on SW9 and SW10 switches. Digit

select lines are connected to PA0 – PA5 pins on the microcontroller sockets, while data lines are connected to RD0

– RD7 pins. Make sure to disconnect other peripherals from the interface lines in order not to interfere with

signal/data integrity.

2.4 8 LEDs Module

The board equipes 8 LEDs for OUTPUT test.All LEDs are connected to RD PORT.We have also provided an

additional PORT headers J4 on the near side of the SW3, so you can access any pin you want from both sides of

the board and make it easily to use this module for other development board.

In this example application,you only need to turn the “SW3” on.

DS18B20 � Digital Temperature Sensor

DS18B20 is a digital temperature sensor that uses 15wire® interface for it’s operation. It is capable of measuring

temperatures within the range of 555 to 128°C, and provides ±0.5°C accuracy for temperatures within the range of

510 to 85°C. It requires 3V to 5.5V power supply for stable operation. It takes maximum of 750ms for the

DS18B20 to calculate temperature with 95bit resolution. 15wire® serial communication enables data to be

transferred over a single communication line, while the process itself is under the control of the master

microcontroller. The advantage of such communication is that only one microcontroller pin is used. Multiple

sensors can be connected on the same line. All slave devices by default have a unique ID code, which enables the

master device to easily identify all devices sharing the same interface.The easyPIC540 provides a separate socket

for the DS18B20. Communication line with the microcontroller is connected via SW4.3.

In order to connect DS18B20 to the microcontroller you must turn SW4.3 “ON”.Prior to using DS18B20 in your

application,make sure to disconnect other unused peripherals, LEDs and additional pull5up or pull5down resistors

from the interface lines in order not to interfere with signal/data integrity.

In this example application,you also need to enable 6 digit 75segment to display temperature value.

ADC input

Digital signals have two discrete states, which are decoded as high and low, and interpreted as logic 1 and logic

0. Analog signals, on the other hand, are continuous, and can have any value within defined range. A/D converters

are specialized circuits which can convert analog signals (voltages) into a digital representation, usually in form of

an integer number. The value of this number is linearly dependent on the input voltage value. Most

microcontrollers nowadays internally have A/D converters connected to one or more input pins. Some of the most

important parameters of A/D converters are conversion time and resolution. Conversion time determines how fast

can an analog voltage be represented in form of a digital number. This is an important parameter if you need fast

data acquisition. The other parameter is resolution. Resolution represents the number of discrete steps that

supported voltage range can be divided into. It determines the sensitivity of the A/D converter. Resolution is

represented in maximum number of bits that resulting number occupies. Most PIC® microcontrollers have 105bit

resolution, meaning that maximum value of conversion can be represented with 10 bits, which converted to

integer is 210=1024. This means that supported voltage range, for example from 055V, can be divided into 1024

discrete steps of about 4.88mV. easyPIC540 provides an interface in form of a potentiometer for simulating analog

input voltages that can be routed to any of the 10 supported analog input pins.

In order to connect ADC INPUT to the microcontroller you must turn SW4.1 “ON”.Prior to using ADC in your



In this example application,you also need to enable 6 digit 75segment to display ADC value.

1838V Remote Control

1838V is miniaturized infrared receivers for remote control and other applications requiring improved ambient

light rejection.The separate PIN diode and preamplifier IC are assembled on a single leadframe. The epoxy

package contains a special IR filter.This module has excellent performance even in disturbed ambient light

applications and provides protection against uncontrolled output pulses.

In order to connect 1838V to the microcontroller you must turn SW4.2 “ON”.Prior to using 1838V in your

EEPROM

EEPROM is short for Electrically Erasable Programmable Read Only Memory. It is usually a secondary storage

memory in devices containing data that is retained even if the device looses power supply. Because of the ability

to alter single bytes of data, EEPROM devices are used to store personal preference and configuration data in a

wide spectrum of consumer, automotive, telecommunication, medical, industrial, and PC applications.

EasyPIC540 supports serial EEPROM which uses I2C communication interface and has 1024 bytes of available

memory. Board contains socket for serial EEPROMs in DIP8 packaging, so you can easily exchange it with

different memory size EEPROM IC. EEPROM itself supports single byte or 165byte (page) write and read

operations. Data rate is 400 kHz for both 3.3V and 5V power supply. I2C is a multi5master serial single5ended bus


www.LogiFind.com 10

that is used to attach low5speed peripherals to computer or embedded systems. I²C uses only two open5drain lines,

Serial Data Line (SDA) and Serial Clock (SCL), pulled resistors. SCL line is driven by a master, while SDA is

used as bidirectional line either by master or slave Up to 112 slave devices can be connected to the same bus. Each

slave must have a unique address.

In order to connect I2C EEPROM to the microcontroller you must turn SW7.4 and SW7.5 “ON”.Prior to using

EEPROM in your application,make sure to disconnect other unused peripherals, LEDs and additional pull5up or

pull5down resistors from the interface lines in order not to interfere with signal/data integrity.

In this example application,you also need to enable 6 digit 75segment and Joystick module.Press “Down” to write

“123456” into the eeprom,and press “Center” to read and display the 65digit 75segment LED module.

DS1302 Real Time Clock

The DS1302 Trickle Charge Timekeeping Chip contains a real time clock/calendar and 31 bytes of static RAM. It

communicates with a microprocessor via a simple serial interface. The real time clock/calendar provides seconds,

minutes, hours, day, date, month, and year information. The end of the month date is automatically adjusted for

months with less than 31 days, including corrections for leap year. The clock operates in either the 24–hour or

12–hour format with an AM/PM indicator. Interfacing the DS1302 with a microprocessor is simplified by using

synchronous serial communication. Only three wires are required to communicate with the clock/RAM: (1) RST

(Reset), (2) I/O (Data line), and (3) SCLK (Serial clock). Data can be transferred to and from the clock/RAM 1

byte at a time or in a burst of up to 31 bytes. The DS1302 is designed to operate on very low power and retain data

and clock information on less than 1 microwatt. The DS1302 is the successor to the DS1202. In addition to the

basic timekeeping functions of the DS1202, the DS1302 has the additional features of dual power pins for primary

and back–up power supplies, programmable trickle charger for VCC1, and seven additional bytes of scratchpad

memory.
