12+
Overview
13+
--------
14+
15+
The EVAL-CN0565-ARDZ is a specialized evaluation board for Electrical
16+
Impedance Tomography (EIT). Designed to be cost-effective and
17+
non-radiative, it utilizes impedance measurements to visualize internal
18+
structures. The board can handle setups with up to 24 electrodes,
19+
supported by a 12-channel crosspoint switch for efficient
20+
multi-electrode operation. Enhanced safety and reliability are
21+
prioritized through its power isolation features. Aligning with Arduino
22+
standards, this board is compatible with various development platforms
23+
and serves well in applications requiring detailed electrical impedance
24+
analysis, particularly beneficial in non-invasive medical imaging.
25+

Power Supply Requirements
37+
~~~~~~~~~~~~~~~~~~~~~~~~~
38+
39+
The EVAL-CN0565-ARDZ board relies on a 5 V supply provided by the host
40+
platform. This supply powers an ADuM5020 isolated DC-to-DC converter,
41+
which generates an isolated 5V output at 500 mW. This isolated output
42+
drives the impedance measurement circuitry. Additionally, the 5V is
43+
regulated to 3.3V by the ADM7150 to supply 120 mA for components such
44+
as the AD5940. The AD8829 inverter converts the isolated 5V to a ±5V
45+
dual supply for other parts of the circuit, ensuring stable and isolated
46+
power vital for accurate impedance measurements.

No-OS Build Setup

125+
126+

No-OS Supported Examples
129+
------------------------
130+
131+
The initialization data used in the examples is taken out from the
132+
`Project Data Source Path <https://github.com/analogdevicesinc/no-OS/tree/e31142c6e7b08e6b4cee40f1997aef3b48cbca79/projects/cn0565/src>`__.

134+
IIO example
135+
~~~~~~~~~~~
136+
137+
The IIO example code for the EVAL-CN0565-ARDZ board in the no-OS project
138+
interfaces with the AD5940 and ADG2128 components to facilitate EIT.
139+
The code initializes the IIO interfaces for both components,
140+
configures UART parameters, and sets up an array of devices passed
141+
to the IIO application initialization function. It supports various platforms
142+
like STM32 and ADuCM3029, allowing data streaming and interaction
143+
with host systems through the IIO Daemon (IIOD) for real-time data exchange
144+
and device control, crucial for detailed impedance analysis.
145+
146+
This project is actually an IIOD demo for EVAL-CN0565-ARDZ board. The
147+
project launches a IIOD server on the board so that the user may connect
148+
to it via an IIO client. Using IIO Oscilloscope, the user can configure
149+
the ADC and view the measured data on a plot.
150+
151+
If you are not familiar with ADI IIO Application, please take a look at:
152+
`IIO No-OS <https://wiki.analog.com/resources/tools-software/no-os-software/iio>`__.
153+
154+
If you are not familiar with ADI IIO-Oscilloscope Client, please take a
155+
look at:
156+
`IIO Oscilloscope <https://wiki.analog.com/resources/tools-software/linux-software/iio_oscilloscope>`__.
157+
158+
The No-OS IIO Application together with the No-OS IIO AD5940 and ADG2128
159+
drivers take care of all the back-end logic needed to setup the IIO
160+
server.
161+
162+
In order to build the IIO project, make sure you have the following
163+
configuration in the
164+
`Makefile: <https://github.com/analogdevicesinc/no-OS/blob/e31142c6e7b08e6b4cee40f1997aef3b48cbca79/projects/cn0565/Makefile>`__
