I have a NUCLEO-L476RG with X-NUCLEO-IDW01M1 Wi-Fi and X-NUCLEO-NFC05A1 NFC Card Reader expansion boards. I want to create a project that uses both these modules. I've downloaded the X-CUBE-*** software zip files and tried to import them into STM32...

The packaging of these products use the terms "quick" and "easy". In this case it is neither. Why don't you convert the examples to STM32CubeMX so I can at least manually merge these products into my STM32CubeMX-based project without having to tria...

Hello @Logann123321, I am having the same problem with the STM32H7. Did you find a solution for this?

The implementation is not multi-master. The STM32 is always a slave. The handshaking is handled by GPIO. The NSS line is under hardware control of the iMX6. Since the the connection is single slave, someone suggested disabling the hardware NSS on...
