ezLINX™ iCoupler® Isolated Interface Development Environment

ezLINX™ iCoupler® Isolated Interface Development Environment

The ezLINX iCoupler Isolated Interface Development environment provides developers with a cost-effective, plug and play solution for evaluating eight physical Layer, digitally-isolated communication standards(USB, RS-422, RS-485, RS-232, CAN, SPI, I2C and LVDS). The Blackfin ADSP-BF548 processor is used to run the uCLinux operating system and allows for easy customization through the open source hardware and software platform. Development time is significantly reduced for embedded designers and system architects who are designing and evaluating isolated communication standards.The Interfaces on ezLINX use ADI's isolated transceivers with integrated iCoupler and isoPower® digital isolator technology.

Quick Start Installation Setup Guide

The following guides give a complete step-by-step guide for the initial setup of the ezLINX board, including software installation for the ezLINX application, driver installation and setting the IP address. Before starting the setup guide, check that you have all of the necessary items from the following list to complete the setup process:

Hardware

The Hardware of the ezLINX iCoupler isolated interface development environment contains the ADSP-BF548 blackfin processor with 64MB of RAM and 32MB of Flash memory. The Isolated Physical layer communication standards are implemented using ADI's isolated transceivers with integrated iCoupler and isoPower technology. Routing between the various communication standards is implemented at the hardware level. Included are the following:

Isolated USB using the ADuM3160
Isolated CAN using the ADM3053 Signal and Power Isolated CAN transceiver
Isolated RS-485/RS-422 using the ADM2587E Signal and Power Isolated RS-485/RS-422 transceiver
Isolated RS-232 using the ADM3252E Signal and Power Isolated RS-232 transceiver
Isolated I2C using the ADuM1250 and ADuM5000
Isolated SPI using the ADuM3401, ADuM3402 and ADuM5000
Isolated LVDS using the ADuM3442, ADuM5000, ADN4663 and ADN4664

Kernel Update Guide

The ezLINX board allows for the embedded kernel of the Blackfin® Processor to be updated with the latest version of the kernel image file. This will improve the functionality and reliability of the board.

For the step-by-step kernel update guide and the latest image file, follow the link below:

Kernel Update Guide

Kernel Restore Guide

If the kernel image file becomes corrupted then the ezLINX board cannot be connected to the PC application. In this case the factory reset feature can't be used and in order to re-establish the connection the kernel must be restored from the back-up location in the ezLINX board's flash memory. This process can also be used to revert the embedded software on the ezLINX board back to its original version.
