Arduino-Due-Based Dual CAN Bus Interface With RTC And Micro SD

Sorry but this product is discontinued!

We now offer a variety of Arduino-compatible Teensy devices that support the same functionality, and more. Teensy is a line of hardware boards designed to offer maximum I/O capabilities, backed up by a slew of fully featured software libraries designed to run on Arduino.

The jCOM.DUE.CORE-C board combines two of our products into one:

• Dual CAN Bus Interface for Arduino Due
• Due Core - Arduino Compatible SAM3X8E 32bit ARM Cortex M3 Module

In addition, we have added two proven Adafruit components:

• Adafruit DS3231 Precision RTC Breakout Board...
• Adafruit MicroSD Card Breakout Board...

Further onboard components are:

• A 4-pos. DIP switch, readable per digital input
• 4 push-buttons, also readable per digital input
• 8 LEDs, controllable per digital output
• 2 x UART port, compatible with:
• UART GPS Module With Real-Time Clock...
• SAE J1708 to UART Breakout Board...
• RS485 Breakout Board 5 VDC...
• FT232 USB Mini UART Board...
• FT232 USB Micro UART Board...

The CAN Bus section incorporates dual CAN transceivers required by the two integrated CAN ports on the Arduino Due, i.e. they convert the CAN TTL signal into a differential voltage as required by the CAN Bus Standard (ISO 11898).

The jCOM.DUE.CORE-C board is powered either by the USB port connection (either the programming or native USB) or through an external power supply supporting an input voltage of 7 to 36 VDC.

Processor Module:

The Due Core is a microcontroller board based on Arduino Due, featuring the Atmel SAM3X8E ARM Cortex-M3 CPU. It integrates all peripherals required for the MCU, and all GPIO are connected to 2.54mm connectors. As a standard MCU core, the board has the following features:

• Compact size: All components are put on a 54 x 58mm 4-Layers PCB. All IOs are connected to a 116-pin 2.54 standard connector.
• Easy to use: All IOs are connected to 116pin 2.54 standard connector. It requires only a 5 VDC power supply to make it work.
• Stable design: High-quality 4-layer PCB layout, two 5V to 3.3V LDO onboard, one for digital and one for analog processing. Separate AVCC and AGND, to ensure optimum analog performance.
• Easy to set up the development environment: Uploading sketches through standard 6-pin UART interface, standard Micro usb connector, full use of existing resources.
• User-friendly design: Rich LED status indication, two onboard buttons, one is for MCU reset, and one is for Flash Erase. Unique jumper erase protection against the flash erased by mistake.
• Rich resources: All IOs are available for the user. The onboard I2C EEPROM is designed to compensate for the shortcomings of the standard SAM3X8E, which has no built-in EEPROM.

Programming Arduino - Getting Started With Sketches
by Simon Monk

Clear, easy-to-follow examples show you how to program Arduino with ease! "Programming Arduino: Getting Started with Sketches" helps you understand the software side of Arduino and explains how to write well-crafted Sketches (the name given to Arduino programs) using the C language of Arduino. This practical guide offers an unintimidating, concise approach for non-programmers that will get you up and running right away.

Programming Arduino: Getting Started with Sketches explains basic concepts and syntax of C with simple language and clear examples designed for absolute beginners - no prior knowledge of programming is required. It leads you from basic through to advanced C programming concepts and features dozens of specific examples that illustrate concepts and can be used as-is or modified to suit your purposes.

• All code from the book is available for download.
• Helps you develop working Sketches quickly.

Coverage includes: C Language Basics; Functions; Arrays, Strings; Input / Output; Standard Library Goodies; Storage; LCD Displays; Programming for the Web; Program Design; C++ and Library Writing
