Hello.

I have nothing connected to my Max32 usb, pin0 and pin1, but sometimes tx/rx leds flash without reason. My code uses serial2 (gps) and serial3 (max485), but nothing about serial0.

I'm trying to get a time pattern between flashes but I can't.

Is this behavior normal?

Thank you

Does this happen while you are running a sketch or while your in the bootloader?

Are you using the Max32 Usb for Serial or just the Max32 board variant?

You can communicate with the Max32 either over Serial (via FTDI chip) or over USB directly using the Network Shield.

If you don't understand the question then its probably the former.

Serial0 is not used. Serial1 is used for rs485 communication Serial2 rx is used for gps communication Nothing else.
