Multiple X-Nucleo-Out02A1 Expansion Board Setup - ST X-NUCLEO-OUT02A1 Getting Started

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.

Step 1. Set the proper configuration for J6, J7 and OUT_EN signal on the two X-NUCLEO-OUT02A1.
Step 2. Connect the
boards through the Arduino connectors.
Step 3. Follow the steps described in
