Introduction to Arduino Due

Hello respected student I hope you all are doing great. In today’s post, we will have a detailed look at Introduction to Arduino Due.  It is a microcontroller based on the Atmel SAM3X8E ARm Cortex-M3 central processing unit. This first Arduino created on the thirty-two-bit ARM core microcontroller is Arduino Due. In this module there are fifty-four pinouts assembled through which twelve can be used as pulse width modulation outputs pints, twelve pinouts are used as analog inputs four pinouts used as UART.

Over this board, every parameter required to operate the controller is assembled for use of these features just attach it with the computer through a micro USB for the power supply or you can deliver power through the use of ACtoDC converter. This module is operatable with all types of Arduino categories that operate on the 3.3 volts and it can be interfaced with the pinout of Arduino 1.0. In today’s post, we will have a detailed look at its working, applications, pinouts, and some other related parameters. So let’s get started with

Introduction to Arduino Due

• The first type of Arduino created which follows the thirty-two-bit ARM structure is Arduino Due. Normally another Arduino board is based on the structure of Atmega 328.

• In this category of Arduino Atmel SAM3X8E ARM Cortex-M3 microcontroller exits. This module consists of fifty-four pinouts.
• Out of these fifty-four pinouts, twelve operate as pulse width modulation outputs twelve as analog inputs four are UARTs and the clock given to this board has a frequency of eighty-four megahertz.
• In this board, USB OTG can be connected, and two analogs to digital converters can be connected with this module. Two TWi, a power jack SPI header erase button, and a lot of other functions that make your task easy are available in this module.
• There are some other features it provides like DAC, acoustic, DMA, multiple tasking performing library, and some others.
• To protect from electric shock this module is covered with a plastic sheet that makes it secure for users.
• For writing the code of the project that you are performing at the ARM processor you must require the current used model of Arduino IDE:1.5.
• In this board, JTAG is assembled to make sure of the connection between the pinouts of the board.
• Other types of Arduino’s used five volts for their operation but this model operates on the 3.3 volts. A larger value of voltage can be dangerous for the board and affect its performance.

Features of Arduino Due

• These are some pinouts of Arduino due which are described here with the details.
• The SAM3X8E thirty-two-bit ARM microcontroller is used in this Arduino.
• This module operates on 3.3 volts.
• The value of extreme current given at the input and output pinouts of these modules is three-ampere milliamperes and fifteen milliamperes.
• The net current drawn from all pinouts is one thirty milliamperes.
• The flash memory of 512KiloBytes exits on this board.
• Sixteen kilobytes of EEPROM exits on this board.

• It has ninety-six bytes of inner random access memory.
• The inner clock has a twelve megahertz frequency and the exterior clock has eighty-four megahertz frequency.
• The temperature over which it works is -40ºC to +85 centigrade.
• The creator of this module is Arduino.cc.
• Arduino Software (IDE) is used for the operation of this board.
• This board has one reset button and one erasable button.

Arduino Due Pinout

• There are fifty-four pinouts are designed on this board which is discussed here with the details.

VIN: 

• In this pin input voltage is provided

5 V:

• Here a 5volt regulator is provided for the board.

3.3 V:

• These voltages provide a regulator and the high current that can pass from pin is about 800mA. it also provides power to the controller.
• GND:
• Here ground connected

IOREF:

• Here reference voltage provided

Digital Input / Output pins

• it has 5 digital pins and operates with 3.3 volts. The current range is  3 mA to 15 mA

TX:

• It employed for the transmission of TTL serial data

RX:

• This pin is used for receiving TTL series data

PWM:

• here 8-bit pulse width modulation is provided and resolution is varied with use of analogWriteResolution () function.

SPI:

• It is for SPI communication

Analog pins:

• It has 12 pins that are analog and comes with 12 bits of resolution

AREF:

• These are referee voltage for analog inputs

Reset:

• It reset controller

Erase:

• it reduces data stored in the board

DAC1 and DAC2:

• These pins are used for analog output of 12-bit resolution through using the analogWrite () function. The output voltage value is 0.55 volts to 2.75 volts.

TWI 1 and TWI 2:

• It used for TWI communication

UART:

• it used to provide serial communication and comes with 4 pins, which helps to provide communication with different devices

Where we can use ARDUINO DUE

• The Arduino board is very commonly used in different types of engineering and embedded projects but Arduino Due is very little used since its controller is ARM and operating voltage is 3.3 volts while other Arduino modules operate on five volts so it is not compatible with some sensors.
• It is preferred for complicated projects such as CN or three-dimensional printers.
• As it is an open-source module we can get every kind of data through this module and customize it when required.
• Before using this module there are some factors you must keep in mind are explained here.

Factor One

• In such a system where large processing is required Arduino UNO and NANO perform limited operation due to their clock speed of sixteen megahertz. While DUe has a five-time larger clock speed of eighty-four megahertz and can perform a function that is not done by the other boards.

Factor two

• If you are working in such a project where you have to connect numerous devices in a single unit then Arduino due is preferred since it has fifty-four pinouts

Factor three

• For such an application where the analog output is needed, Arduino Due is preferred over other types of Arduino.

Factor Four

• Due to numerous pulse widths and analog to digital converter pinouts, Arduino due is preferred over other categories of Arduino.

Factor Five

• In such an application where high electromagnetic interference exists due Arduino is preferred due to its CAN interfacing which can handle such types of applications.

Arduino Due vs Arduino Mega

• Arduino due comes with larger memory and good processing power as compared to Arduino Mega.
• Arduino due supported by ARM controller and Arduino Mega is an ATmega2560 Microcontroller.
• The library supported the  ATmega2560 Microcontroller rather than Arduino Due.
• Arduino due comes with 54 digital pins and 12 analog pins and Arduino mega has 14 analog pins and  54 digital pins.

Arduino Due vs Arduino UNO

• Arduino Due has 54 pins and 12 analogs and Arduino uno has 6 analog pin inputs and 14 digital pins.
• Arduino is due is based on an ARM Microcontroller and Arduino UNO on an ATmega328 Microcontroller.
• Arduino’s Due voltage range is 3.3V, and Arduino UNO uses  5V.

Applications of Arduino Due

• These are some applications of Arduino Due.
• It is used in different types of electronic and embedded projects.
• It is used in power supply networks.
• It is used in IoT projects.
• In industries for controlling different devices.

Arduino Due Programming

• The Arduino is programmed with the use of Arduino 1.5 and higher modules.

Programming port:

• For using this port choose Arduino due in Arduino IDR. Connection programming port of controller with computer. The programming port uses 16U2 for USB to serial chip connected with the first UART of SAM3X (RX0 and TX0).
• The 16U2 comes with two pins configured with Reset and Erase pins of  SAM3X.
• Opening and closing a programming port configured with 1200bps triggers a hard erase, process of the SAM3X chip, operating Erase and Reset pins on SAM3X before connection with UART. This port is recommended for the Due module. It is best as compared to soft erase which is on the Native port.
