Usb uart not working?

1

Hi. I use an arduino micro. I currently have stuff working with uart1 but would like to use the usb uart node instead.
As soon as i place it, I get this error:
Begin compiling code for the board Arduino Micro :package:

C:\Users\troelsj\AppData\Local\Temp\xod_temp_sketchbookVPDSb6\xod_1734721504942_sketch\xod_1734721504942_sketch.ino:1698:15: error: explicit specialization in non-namespace scope ‘struct xod::xod__uart__uart_usb::Node’
template <>
^

Error during build: exit status 1

What can I do?
Thanks

This type of error could mean that option is not supported on the board you have selected, but it might be some other issue someone else can help you with.

The arduino micro should support this as far as i know though. But thanks

My friend, on the xod website there is an instruction with a sample of using uart. The problem is that boards like uno, nano, micro have only one standard uart which is used to load the program. Use the soft-uart node as in the sample and everything will work.Set a low speed (4800) and select ports that support external interrupts. I already used it in my project with nano, everything worked.

Thanks! But according to my research I need to use the usb-uart node in my project, and that is throwing an error (see my first post). I have to admit I don’t fully understand the differences, but it seems that I need USB-serial communication. It seems that soft-uart can’t communicate directly over usb, which is what I need.

This is not a problem either. There are usb-uart converters. This allows you to use a simple soft-uart to receive or send data via usb.

Thanks! I will use this as a last resort then. But would be nice if I could just stick to the existing USB port.
