expected declaration specifiers or '...' before '....'

Hi!

I'm working with STM32CubeIDE and I want to send data via UART using the code below.

 

char *msg = "Hello\n";
HAL_UART_Transmit(&huart6, (uint8_t *) msg, strlen(msg), 100);

 

But I get an error like this:

What can I do about this issue?

Hello @Sule_Akcay 

I've tested personally using the Nucleo-F756ZG and I can't reproduce the issue. Can you add your project and all details about your board, your IDE version,... Personally, I'm using the CubeIDE  V1.14.1 and everything works fine.

Best Regards.

Did you 

#include <string.h>

?

I didn't understand what the problem was, but creating a new project solved my problem.

Thanks...

When you get errors like that, it generally means that something went wrong sometime earlier in your code - leaving the compiler confused.

You haven't shown enough context to see what that might be.

But as it's fixed now, please mark your last post as the solution - so people can see that this issue is resolved.
