How to feed New Line ('\n') from my Nucleo-F44rZE board to PC terminal?

[TH.16.336]

Hello All,

I am using Nucleo-F44rZE board. From my nucleo board, I want to send a new line char to my terminal which actually has to fee a line in terminal when it recieves it.

I have the following code, which actually prints 0A in my terminal instead of feeding a new line.

uint8_t nl = 0x0A; // ascii value for new line feed

HAL_UART_Transmit(&huart5, &nl, 1, 100); // Go to the next line

Please help to understand this behavior and find the solution for this.

Is your terminal printing in hex and not interpreting the ascii meaning of a character?

Your question makes sense, in my view.

@TH.16.336​ What happens if you send other data values (0x31 => "1" or 0x42 => "B") ?

What Terminal application, in what mode?

Try different terminal software. Some will show CR LF info

Things like RealTerm have an ASCII, ANSI and HEX mode

Yes it was printing in hex. I am using real term.

when I switched to ASCII mode, the issue resolved. It was feeding the new line.

Thanks for the reply.

As already asked, what "terminal" are you using?

What happens if you connect two instances of that terminal together (via a "null modem") ?

If you get the same behaviour (LF printing as "0A" instead of doing a line-feed) with that - then it's clearly an issue with your terminal, not the Nucleo!

Note that LF = Line Feed, and CR = Carriage Return - you may need both to get a new line ...
