IOM6 ADIO
IOM6 ADIO - A part of the IOM6 product line and extends the functionality of the iC5700
BlueBox, enabling the monitoring of analog and digital signals synchronous to program
execution information. This allows network activity and code execution to be examined side-
by-side within our development software winIDEA.
The IOM6 ADIO provides two analog inputs, two analog outputs and up to 24 digital
inputs/outputs, which for example can be effectively used for automated Hardware-In-The
Loop (HIL) testing.
Provided inputs make possible measuring power consumption of the Embedded system or
part of it. Using digital inputs, optional SPI Protocol Analyzer is available for easy monitoring
of two SPI interfaces within the embedded target either alone or in conjunction with the
program execution.
winIDEA - Integration Development Environment (IDE) delivers the visual insights required to
debug your embedded application. At the simplest level, winIDEA provides all the usual
functionality of an IDE (breakpoints, stepping and device programming). Supported by a target
microcontroller, winIDEA can also visualize the timing and code coverage of the application
via the trace interface, as well as combine data captured by the IOM6 Accessories. Various
third-parties also provide software tools to perform advanced worst-time-execution analysis
based upon the data winIDEA can export. When a Real-Time Operating System (RTOS) is in
use, the state of the RTOS and its tasks can also be visualized. More information
isystem.com/winideaide.
testIDEA - testIDEA environment simplifies the development of unit tests for embedded
applications. By making use of the winIDEA environment, this application makes it easy to
locate source code functions and generate test cases for them. Tests are then executed using
the Original Binary Code (OBC) method, testing the object code running on the target
microcontroller. The tests, which are stored as YAML files, can easily be added to a project,
maintained in a repository, and then automatically executed together with Continuous
Integration (CI) tools such as Jenkins. More information isystem.com/testidea.
isystem.connect - There are times when it is more efficient to write a script to execute a task
that requires many clicks within a visual development environment. This is where our Software
Development Kit (SDK) isystem.connect comes in. The well-documented interface provides
access to Python, Java, and other languages so that any action available within winIDEA and
testIDEA can be scripted. Scripts can also be executed directly from within winIDEA, thereby
allowing the developer to extend its functionality. More information isystem.com/sdk.
iSYSTEM's solutions run under Microsoft® Windows®, GNU, Linux OS; or optionally within the
Eclipse environment via a plugin. Software can be downloaded from the Downloads page at
http://www.isystem.com.

For further information about ADIO digital input/output, analog input/output Configuration go
to winIDEA Help - Network description chapter.

SPI Protocol Analyzer
The Serial Peripheral Interface (SPI) is a synchronous serial communication interface
specification used for short-distance communication, primarily in embedded systems. There
are four SPI interface signals: MISO (Master Input Slave Output), MOSI (Master Output Slave
Input), SCK (Serial Clock), CS/SS (Chip Select or Slave Select). Information is transferred
between Master and Slave on defined clock edge when CS/SS is in active state (if CS/SS is
used). Active state of Chip Select (LOW or HIGH) is configurable.
Using digital inputs, optional SPI protocol analyzer is available for easy monitoring of two SPI
interfaces within the Embedded system either alone or in conjunction with the program
execution. SPI protocol analyzer modules (SPI1, SPI2) are by default disabled because they
consume digital I/O connectors or BANKS as specified in winIDEA. Note that if SPI1 is enabled
it consumes DIO BANK0, and if SPI2 is enabled it consumes DIO BANK2.
To configure the SP1 and/or SP2 open Hardware menu / Options / FNet tab and double-click
FNode ADIO to open the ADIO configuration dialog.
1. Open SPI1 tab (or SPI2 tab) and enable SPI.
2. Click Network and give it a meaningful name which is shown in the Analyzer window.
3. Add SPI description files (*.spi). Find iSYSTEM SPI protocol description format in winIDEA
Help.
4. Chip Select is required. Click Edit and select CS0, CS1 or CS2.
NOTE: Make sure physical SPI signals are connected according to the Pin mapping on DIO
BANK0 (or DIO BANK2).
For further information about SPI Protocol Analyzer Configuration go to winIDEA Help.

Use Cases
Following use cases depict connection possibilites of digital/analog input/output connectors
and embedded target, and as well iSYSTEM Power Probe for target power consumption
measurement. winIDEA plugin HIL Monitor provides the monitoring and manipulation
capability of the input/output signals. All monitored signals can be also traced wih the
winIDEA Analyzer tool.
1. Observing digital inputs
1. First connect ground potential (GND) of the Digital I/O connector with the monitored
Embedded system ground (GND) using provided clip wires. Note that all eight GND signals
of each Digital I/O connector are internally connected.
2. Use clip wires to connect signals from the Embedded system to the pins of Digital I/O
connector D0 (or D1 or D2 or D3).
3. Configure used Digital I/O connector (D0 or D1 or D2 or D3) for input operation and its
input voltage range in winIDEA. Note that all eight signals of the selected Digital I/O
connector are set as inputs.
Configured input (or output) operation for the individual Digital I/O connector applies to all 8
available digital signals on the connector. Mixing input and output signals within one Digital
I/O connector is not supported.
2. Observing analog inputs
Use standard oscilloscope probes to connect analog inputs AIN0 respectively AIN1 to the
Embedded system.
3. Output analog signal
1. First connect ground potential (GND) of the AOUT0, AOUT1 connector with the Embedded
system ground (GND) using provided clip wires. All five GND signals of the AOUT0, AOUT1
connector are internally connected.
2. Use clip wires to connect AOUT0 respectively AOUT1 pin to the Embedded system.
3. Voltage output range is configured in winIDEA.
4. Output digital signals
1. First connect ground potential (GND) of the Digital I/O connector with the Embedded
system ground (GND) using provided clip wires. All eight GND signals of each Digital I/O
connector are internally connected.
2. Use clip wires to connect signals from the Embedded system to the pins of Digital I/O
connector D0 (or D1 or D2 or D3).
3. Configure used Digital I/O connector (D0 or D1 or D2 or D3) for output operation and its
output voltage range in winIDEA. Note that all eight signals of the selected Digital I/O
connector are set as inputs.
Configured output (or input) operation for the individual Digital I/O connector applies to all 8
available digital signals on the connector. Mixing input and output signals within one Digital
I/O connector is not supported.

5. Power consumption measurements
Picture 2 below explains how the power consumption can be measured with two voltmeters
respectively with two analog inputs in respect to the IOM6 ADIO.
When measuring power it is necessary that both the voltage and the current are measured at
the same time, and that the relationship between these two is taken into account. The ways
the voltage and current are measured have a great influence on the accuracy. The advantage
of power measurement with a shunt resistor method is that it delivers precise measurements,
it allows a quick detection and elimination of faults.
A shunt is a low-value resistor, connected in series to the load. The “current” through the shunt
is measured by measuring the voltage drop on the shunt and the power is then calculated
with formula:
If the target or just part of the electronic, where we want to measure the power along the
application execution, provides already the shunt resistor in series to the load, user can
connect necessary RS+, RS-, AIN and GND signals from the Power Sense connector to the
target using provided clip wires.
Alternatively, iSYSTEM provides Power Probe featuring already a shunt resistor and different
connection possibilities. With this it’s quick and easy measuring power consumption on
electronic circuit (e.g. evaluation board), which gets power over standard jack and external
power supply.

5.1. Connecting with clip wires
For manual connection use set of clip wires which are delivered with the IOM6 ADIO package.
NOTE: Make sure that the Embedded system and BlueBox are not powered.
For voltage measurement
1. Connect GND from the Power Sense connector to the circuit ground of the Embedded
system.
2. Connect AIN input from the Power Sense connector to the supply voltage of the Embedded
system.
3. If the voltage is higher than 5V, use a suitable resistor divider. Enter the divider ratio as a
Voltage/Multiply factor in winIDEA configuration dialog.
For current measurement
1. Connect GND from the Power Sense connector to the circuit ground of the embedded
system.
2. Connect RS+ signal pin from the Power Sense connector to a high side of the shunt (see
Picture 2).
3. Connect RS- signal pin from the Power Sense connector to a low side of the shunt (see
Picture 2).
4. Specify the resistance of the R shunt resistor in winIDEA configuration dialog.
5. Switch ON BlueBox and embedded system power supply.
Picture 2 depicts power measurement setup. Connect with clip wires where blue arrows
indicate.
NOTE: The full-scale shunt voltage range is 250mV (e.g. a 1Ω shunt resistor gives a current
range of 250Ma).

5.2 Power Probe
Power Probe (Picture 3) replaces wire connections described in section 5.1.
It connects between a target power supply and a target board as shown on the next Picture 4.
Connectors, Jumpers and a Switch
P1 and P2 (1 and 2 on the Picture 3) – Target power supply inputs. Use one or the other.
Maximum voltage is 20V.

P3 (3 on the Picture 3) – 10-pin IDC connector to connect the Power Probe with the IOM6-ADIO
using provided 10-pin ribon cabble.
P4 and P5 (4 and 5 on the Picture 3) – Power supply output towards the target.
ST1 (6 on the Picture 3) – BNC connector
JB1 (7 on the Picture 3) – Jumper block for selecting different shunt resistors.
NOTE:
1) Excessive current will burn the resistors.
2) Never set more than one jumper!
3) Selected shunt resistors must handle the heat generated by the power dissipated on them.
Three of the five available positions are populated with resistors:

The remaining two positions are available for a custom user setup with unpopulated resistors
R5 and R6.
NOTE: With lower shunt resistor values also the JB1 jumper resistance starts to play a role and
may influence the measurement. This can be easily compensated by slightly increasing the
shunt resistance value in the winIDEA setup dialog, by 0.01Ω, for example.
JB2 (8 on the Picture 3) – Jumper block for selecting different voltage ranges.
NOTE: Never set more than one jumper!
Three of the five available positions are populated with resistor dividers:

The remaining two positions are available for a custom user setup with unpopulated resistors
R12 and R13. The lower part of the voltage divider is set by the R9 of 10kΩ.
SW1 (9 on the Picture 3) – Switch connecting/disconnecting P1/P2 connectors with P4/P5
connectors respectivelly “power on switch” for the embedded targeted connected to P4 or P5
connector.
LD1 (10 on the Picture 3) – LED indicator. Note that the LED needs a very small current to light
and may glow because of a parasitic current flowing, for example, even when the emulator
switched on and the target is off.
Connection Procedure
1. Make sure that the Embedded system and BlueBox are not powered.
2. Switch SW1 is in OFF position.

3. Configure 0.25 A, 1A or 2.5A current range on JB1 depending on the expected range of the
measured current. To be on the safe side, you can start with 2.5A setting.
4. Configure 5, 10 or 20V voltage range on JB2 depending on the embedded target power
supply range.
5. Connect power supply for the Embedded system to P1 or P2.
6. Connect Embedded system to P4 or P5.
7. Connect P3 to the IOM6 ADIO Power Sense connector.
8. Power on BlueBox.
9. Power Embedded system by switching SW1 to ON position.
