 ====== EVAL-ADM2587EARDZ Arduino Shield & EVAL-ADM2587ERPIZ Raspberry Pi Shield ======

Use the [[adi>EVAL-ADM2587EARDZ]] Arduino Shield with the widely available Arduino UNO to easily evaluate the [[adi>ADM2587E]] RS-485 transceiver, the [[adi>ADM3260]] I2C isolator, and the [[adi>ADuM3151]] SPI isolator.
The ADM2587E, ADM3260, and ADuM3151 integrate Analog Devices, Inc., iCoupler® technology. The ADM2587E and ADM3260 also integrate Analog Devices isoPower dc-to-dc converter into a single package.

The EVAL-ADM2587EARDZ Arduino Shield & [[adi>EVAL-ADM2587ERPIZ]] Raspberry Pi Shield use an identical basic design, J1 Raspberry Pi connector populated for EVAL-ADM2587ERPIZ, and the J5 Arduino connector block is populated for the EVAL-ADM2587EARDZ. 

This Wiki guide provides hardware references and Arduino software for full integration of the EVAL-ADM2587EARDZ in a demonstration platform. This wiki guide also provides hardware references and Raspberry pi sample code for the EVAL-ADM2587ERPIZ.

===== Connectors and Jumper Configurations =====
{{ :resources:eval:user-guides:eval-adm2587erpiztop.jpg?nolink&600 |}}

^Port          ^Function          ^
|J1 | This is a GPIO female connection to be used with the raspberry pi version of the board EVAL ADM2587ERPIZ.|
|J2 | This is used to connect the ADM3260 isolated I2C or ADuM3151 isolted SPI to external devices. |
|J3 | This is used to supply power to the logic side of the board. |
|J4 | This 6-way connector is used for an RS-485 bus cable.  A and B are the ADM2587E receiver inputs while Y and Z are are the driver outputs. Ground terminals are provided for cables with ground wires.|
|J5 | This is a GPIO male connection to be used with the Arduino version of the board EVAL ADM2587EARDZ |
|LK5 | When LK5 is closed the receiver input B pin is connected to the driver output Z pin. When both LK5 and LK7 are closed the board is configured for half duplex operation. When both LK5 and LK7 are open the board is configured for full duplex operation.|
|LK7 | When LK7 is closed the receiver input A pin is connected to the driver output Y pin. When both LK5 and LK7 are closed the board is configured for half duplex operation. When both LK5 and LK7 are open the board is configured for full duplex operation.|

===== EVAL-ADM2587EARDZ Arduino Shield & EVAL-ADM2587ERPIZ Raspberry Pi Shield Example Code =====

\\ Arduino UNO code is provided so that that user can perform a loopback test mode for the ADM2587E RS-485 transceiver. Load the  'eval_adm2587eardz_arduino_shield_example_code.zip' sketch to an Arduino UNO. Connect jumpers LK5 and LK7. Use an oscilloscope to measure the waveforms on the DI, /RE, A, B, Y, Z, and RxD test points. The Arduino sketch outputs a constant bit stream on the ADM2587E DI pin. The loopback test echos the DI voltage waveform to the RxD pin. The bus voltages on the A, B, Y, and Z pins can also be measured.

Raspberry pi code is also provided so that the user can perform a loopback test mode for the ADM2587E RS-485 transceiver. Load the 'eval_adm2587erpiz_raspberry_pi_shield_example_code.zip' sketch to the Raspberry pi. Voltage waveforms can be measured on the RS-485 logic and bus interface pins, similar to the Arduino example given above.
