ST X-NUCLEO-OUT02A1 User manual

Introduction
The STSW-IFAPGUI is the common graphic user interface designed to facilitate the control of the IPS and IO-Link evaluation
boards based on STM32 Nucleo.
The GUI automatically detects the firmware version running on the STM32 Nucleo board connected to your laptop/PC via USB
cable.
For the X-NUCLEO-OUT02A1, the GUI works in combination with the X-CUBE-OUT02 firmware, running on the NUCLEO-
F401RE board and controlling the features of the ISO8200AQ such as the frequency and duty cycle of each output channel and
the internal status of the IC.
The GUI is available free of charge on www.st.com.

1STSW-IFAPGUI overview
Figure 2. STSW-IFAPGUI overview
The STSW-IFAPGUI is a Windows®-based application able to control the X-CUBE-OUT02 and automatically
identify the firmware version.
The GUI can control the firmware for two X-NUCLEO-OUT02A1 boards stacked together by activating daisy
chaining via proper jumper configuration.
The GUI features:
• single or dual chip (daisy chaining) configuration
• output channel control by switching frequency (0 to 100 Hz) and duty cycle (0 to 100%)
• output enable signal control
• start/stop SPI signal sequence
• power good open drain monitoring status (ON/OFF)
• common fault open drain monitoring status (ON/OFF)
• output channel thermal fault monitoring status

2Software installation
The STSW-IFAPGUI software is designed to run on Microsoft® Windows.
To install the GUI:
Step 1. Run Setup_ STSW-IFAPGUI.exe included in the package
Step 2. Follow the installation instructions

3Running the graphical user interface
3.1 Single X-NUCLEO-OUT02A1 expansion board setup
Step 1. Connect the STM32 Nucleo board flashed with X-CUBE-OUT02 to the X-NUCLEO-OUT02A1 through
the Arduino connectors.
Step 2. Connect the stacked boards to your PC/laptop USB port through a mini-USB cable.
The STM32 is supplied by 3.3 V from the USB supply and the flashed firmware starts running.
By default, in the X-NUCLEO-OUT02A1, J8 is closed between pins 5-6 and the ISO8200AQ digital side
is supplied by the same 3v3 of the micro.
Step 3. Launch the GUI from [Start]>[STMicroelectronics]>[STSW-IFAPGUI]>[MDGUI.exe]
When the application starts, the firmware running on the STM32 is automatically detected and a COM
port is opened for communication.
Step 4. Click on the GUI STM32 Nucleo icon only after it becomes blue (it is green until the firmware
identification is completed).
Figure 4. STSW-IFAPGUI selection window
After having clicked the blue icon, the Device Count window appears.
Figure 5. STSW-IFAPGUI device count
Step 5. Select "1" in the Device Count window and then click OK to activate the ISO8200AQ control window.

Step 6. Supply the ISO8200AQ power stage with a 24 V rail via J1 connector.
Step 7. Click on the GUI [Refresh] button to align the application board and the GUI status.
Step 8. Select the desired switching frequency and duty cycle of the output channels to be activated (ON/OFF).
Note: 0 Hz stands for channel OFF; duty cycle 100% stands for channel always ON.
Step 9. Tick the OUT_EN1 to activate the ISO8200AQ output enable signal.
Step 10. Click [Start] to activate the SPI communication between MCU and ISO8200AQ.
Now the activated output channels start switching according to the setup defined in Step 7 (green LED
D5 to D12 will be driven accordingly).
When SPI is active, the right side of the GUI (fault monitoring) is automatically updated every 500 ms.
Step 11. The output channels ON/OFF statuscan be deactivated by unticking the OUT_EN1 or by clicking
[Stop].
In the first case, the SPI communication between MCU and ISO8200AQ remains active, while in the
second case the SPI communication stops.
3.2 Multiple X-NUCLEO-OUT02A1 expansion board setup
When two X-NUCLEO-OUT02A1 expansion boards are stacked (daisy chaining), follow the procedure below.
Step 1. Set the proper configuration for J6, J7 and OUT_EN signal on the two X-NUCLEO-OUT02A1.
Step 2. Connect the STM32 Nucleo board flashed with X-CUBE-OUT02 to the two X-NUCLEO-OUT02A1
boards through the Arduino connectors.
Step 3. Follow the steps described in Section 3.1 Single X-NUCLEO-OUT02A1 expansion board setup (from
step 2 on).

Step 4. When the evaluation session finishes, stop the SPI communication, close the GUI, remove the 24 V
from J1 and disconnect the USB cable from the STM32 Nucleo board.

4STSW-IFAPGUI control panel for X-NUCLEO-OUT02A1
This control panel (see Figure 6) shows three main function areas:
• Output channel activation (OUT_EN, switching frequency, duty cycle)
• SPI activation (start/stop)
• Fault monitoring (power good, common fault, per-channel thermal fault)
4.1
Note:
4.2
4.3
Output channel activation
You can set the switching frequency and duty cycle driving each output channel by editing the text boxes of this
section of the GUI.
The switching frequency can be set from 0 Hz (channel always OFF) to 100 Hz.
The duty cycle can be set from 0% (channel always OFF) to 100% (channel always ON).
You can also control the ISO8200AQ output enable signal by ticking the OUE_ENx box: when ticked, the output
enable pin is forced high, otherwise it is off.
the output channel ON/OFF configuration set in the GUI is transferred to the ISO8200AQ only when the SPI
communication is activated (see next chapter).
SPI activation
The ISO8200AQ output channels are controlled by the MCU SPI.
The STSW-IFAPGUI activates/deactivates the STM32 SPI interface by clicking the start/stop button.
Although the SPI is activated by the start button, you have to tick the GUI OUT_ENx box to enable the outputs.
Fault monitoring
The ISO8200AQ can report to the MCU a wide set of information.
Voltage drop on supply rail
The supply voltage is monitored by an embedded circuitry and the power good open drain pin is activated (forced
low) when the supply voltage on J1 goes below 16.5 V.
SPI communication error (modulo-8 violation)
The internal logic controls if each SPI communication contains 8 bits on the SDI (MOSI) line. In case of violation,
the common fault pin is activated (forced low).
Communication error internal to ISO8200AQ
The internal logic controls if any communication error occurs between the ISO8200AQ logic and process stage.
The common fault is activated (forced low) in case of internal commutation error.
Output channel thermal fault
The common fault pin is forced low when one (or more) ISO8200AQ channel has triggered the thermal shutdown
threshold. The MCU recognizes which channel is in thermal fault by reading the byte sent back by the
ISO8200AQ through the SDO (MISO) line.
When SPI is active, the whole status information of the ISO8200AQ is automatically refreshed every 500 ms.
When SPI is not active, the status of ISO8200AQ can be showed on the GUI by clicking the [Refresh] button.
