+Introduction
+============
+
+This page gives an overview of using the ARM platforms supported 
+firmware example with Analog Devices AD3530r Evaluation board and SDP-K1 controller board. 
+This example code leverages the ADI developed IIO (Industrial Input Output) ecosystem to 
+evaluate the AD3530r device by providing a device debug and data capture support.

+
+The interface used for communicating with PC based IIO clients is either Virtual Serial Or UART. 
+IIO Firmware leverages the ADI created no-os and platform driver software layers
+to communicates with IIO device.
+
+.. note::
+
+   This code has been developed and tested on the SDP-K1 Controller Board with
+   Arduino headers. However, the same code can be used with minimal modifications
+   on any STM32 board which has Arduino Header support on it.

+====================
+Hardware Connections
+====================
+
+Required: SDP-K1, EVAL-AD3530RARDZ board
+and USB cable.
+
+Connect the EVAL-AD3530RARDZ board to SDP-K1 board (or any STM32 controller 
+board). Connect controller board to the PC using the USB cable.

+Jumper Settings
+===============
+
+**SDP-K1:**
+
+Connect the VIO_ADJUST jumper on the SDP-K1 board to 3.3V position to drive SDP-K1 GPIOs at 3.3V
+
+**EVAL-AD3530R:**
+
+* Please refer to the respective board user guide on the product page of the chosen device.
+
+.. Communication Interface section:
+
+SDP-K1 is powered through USB connection from the computer. SDP-K1 MCU board
+acts as a serial device when connected to PC, which creates a serial ports to connect to IIO
+client application running on PC. The serial port assigned to a device can be seen
+through the device manager for windows-based OS as shown below:

+
+.. note::
+
+   The serial port naming is used differently on different operating systems.
+   For example, Linux uses terms such as dev/ttyUSB* and Mac uses terms such as dev/tty.USB*.
+   Please check serial port naming for your selected OS.
