Fork of X_NUCLEO_IDB0XA1 by
Arduino Connector Compatibility Warning
X-NUCLEO-IDB04A1 and X-NUCLEO-IDB05A1 are Arduino compatible with an exception: instead of using pin D13
for the SPI clock, they use pin D3
.
The default configuration for this library is having the SPI clock on pin D3
.
To be fully Arduino compatible, X-NUCLEO-IDB04A1 and X-NUCLEO-IDB05A1 need a small HW patch.
For X-NUCLEO-IDB04A1 this patch consists in removing zero resistor R10
and instead soldering zero resistor R11
.
For X-NUCLEO-IDB05A1 this patch consists in removing zero resistor R4
and instead soldering zero resistor R6
.
In case you patch your 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 pin D13
for the SPI clock, please be aware that on STM32 Nucleo boards you may not drive the LED, otherwise you will get a conflict: the LED on STM32 Nucleo boards is connected to pin D13
.
Referring to the current list of tested platforms (see X-NUCLEO-IDB04A1 and X-NUCLEO-IDB05A1 pages), the patch is required by ST-Nucleo-F103RB; ST-Nucleo-F302R8; ST-Nucleo-F411RE; and ST-Nucleo-F446RE.
