      Hello,

      We are designing a system that needs to respond to two external digital signals, ideally generating an interrupt. J10:7 PGIO_64 is designated for interrupt, but I don't see a second such designated pin. In a separate post I see mention of GPI_46 on some versions of the VOXL 2, but nothing for the Mini. Can I configured GPI_46 to generate an interrupt in the VOXL 2 Mini? Or other recommendations?

        Hi @dougmiller
        If your VOXL 2 Mini is TrustZone Configured for UART over J10, then yes, there are 2 pins available as inputs.
        https://docs.modalai.com/voxl2-mini-connectors/#j10---external-uart
        You can see GPIO_40, GPIO_46 and GPIO_64 are input capable.
        GPIO_40 and GPIO_64 are able to be configured to do wake events in the SoC so they have extra configuration to route to a power manager. Depending on how you write your IRQ routine, that may or may not help.
        Hope this helps!
