    Hello,

    SPI at CONTROLLINO MINI can be used for the RTC OR for the custom peripheral connected to the pinheader, not for both. So your solution and usage of the pin 10 as a slave select signal is correct.

    But in principle you can use all pinheader pins as digital outputs, even the analog and the interrupt ones.

    Best regards,

    Lukas
