Arduino Connector Compatibility Warning
X-NUCLEO-IDB04A1 is Arduino compatible with an exception: instead of using the D13 pin for the SPI clock, it uses the D3 pin.
The default configuration for this library is having the SPI clock on the D3 pin.
To be fully Arduino compatible, X-NUCLEO-IDB04A1 needs a small HW patch which consists in removing zero resistor R10 and instead soldering zero resistor R11. In case you patch the board, then you also have to configure this library to use pin D13 to drive the SPI clock (see macro IDB0XA1_D13_PATCH in file x_nucleo_idb0xa1_targets.h).
If you use the D13 pin for the SPI clock, please be aware that on STM32 Nucleo boards you MUST NOT drive the LED, otherwise you will get a conflict: the LED on STM32 Nucleo board is connected to the D13 pin.
