Building an example(multiple usart).c

[gon3ales]

When I try to compile an example I have an error at those strings:

        fprintf(uart1_io, "Say my name: ");
        fscanf(uart1_io, "%s", buffer);
        fprintf(uart1_io, "So it's %s, You are damn' right.\n", buffer);

Error - incompatible type for argument 1 of 'fprintf'.

I use Atmel Studio 7 (Version: 7.0.2397 - )

Perhaps you should not use "fprintf" but "sprintf"? Although I can't tell you more precisely, as I haven't seen your code ...

I just try to compile your example, didn't change anything. sprintf give same error.

But anyway thanks for library! It's working well!

And what kind of code, if not a secret? Unfortunately, I just don't remember.

Here it is: `

}

}`

Something seems to me that this is not my code ... Did you make a mistake with the email address? 26 октября 2020, 20:04:23, от gon3ales notifications@github.com:

Sorry! Maybe I'am wrong!

I'm just wondering what happened here.

Anyway issue confirmed. I'll look into it soon.
