The Arduino Due is a development board from Arduino based on the Atmel SAM3X8E ARM Cortex-M3 CPU and 32-bit ARM core microcontroller. The board is ideal for larger projects, featuring 54 digital I/O pins, 12 analog inputs, four UART ports, an 84 MHz clock, an USB OTG capable connection, and two digital-to-analog pins. As is customary with Arduino development boards, the Arduino Due is compatible with Arduino shields and other add-on boards to expand its functionality.
The Arduino Due doesn’t include connectivity on its own, so with use in Atmosphere you can either print its data into a debug console, or give it Wi-Fi connectivity by connecting it to an Arduino-compatible Wi-Fi shield. Atmosphere supports the Adafruit WINC1500 Wi-Fi Shield, which features the Microchip WINC1500 Wi-Fi module that includes with a corresponding element by the same name in Atmosphere Studio’s Element Library.
There are no imported sensors or specialized elements or tools native to Arduino Due projects.
Some devices may have limitations or design restrictions that cause unexpected behavior when used with Atmosphere. Specific information and details pertaining to the Arduino Due and its performance on Atmosphere is noted below.
- This platform does not have PWM support
Default Pin Mapping
Atmosphere configures each peripheral to a default pin for every supported device, based on ideal pairing of pins and their usage. The default pin configuration is set for convenience and enables each peripheral to work naturally without needing to be modified.
All pins can be used as general purpose input/output (GPIO) unless otherwise specified.
Arduino Due projects start with the following pin configuration:
||Arduino Connector D0|
||Arduino Connector D1|
||Arduino Connector D2|
||Arduino Connector D3|
||Arduino Connector D4|
||Arduino Connector D5|
||Arduino Connector D6|
||Arduino Connector D7|
||Arduino Connector D8|
||Arduino Connector D9|
||Arduino Connector D10|
||Arduino Connector D11|
||Arduino Connector D12|
||Arduino Connector D13|
||Arduino Connector Analog 0|
||Arduino Connector Analog 1|
||Arduino Connector Analog 2|
||Arduino Connector Analog 3|
||Arduino Connector Analog 4|
||Arduino Connector Analog 5|
The default pin for any peripheral can be changed within an element's properties, from an element that references that particular peripheral.
Internal Arduino Due
The Arduino Due is compiled using the Arduino SDK, so any functions and pin mappings can also be used within Atmosphere Studio.
Below is information regarding the Arduino Due’s exposed peripherals.
This I2C bus is exposed via the SDA and SCL pins on the Arduino header.
This SPI bus is exposed via the MOSI, MISO, and CLK pins on the Arduino SPI connector.
UART1 (USB Debug Console)
This UART is exposed via the USB connector.
This board does not have PWM support.
Programming the Arduino Due involves using the programmer interface in Atmosphere Studio to install embedded firmware.
Prior to programming an Arduino Due, ensure you have the following setup configuration:
- The Arduino Due is connected to the computer via USB to an available communication port.
- The Atmosphere IoT Agent is installed on the computer and running. The Atmosphere IoT Agent is a local application that runs in the system tray and acts as an intermediary between the computer’s connectivity protocol drivers and the browser running Atmosphere.
- An Internet connection is maintained.
- The project to be programmed has been compiled.
With setup complete, you can program the Arduino Due:
- From Atmosphere Studio’s Embedded tab, click the button from the tab’s toolbar. This displays the Program Firmware window.
- Under Device Port, select the communication port the device is connected to.
- Click Program to start programming. When complete, you’ll receive a notification stating the device is programmed with the project’s embedded firmware.
