Hello
I wrote a program in IAR. The program has an error when executing the following line.

UART1_SendData8("A");

The complete program file is available below.
I would be grateful if you could tell me the mistakes of my code.

it is very short code and the error occurs in the last line
and microcontroller modell is STM8S003F3

 

Welcome to AAC.

No one is going to download and decompress your file, so you‘ll need to use [CODE] tags available in the menu in the editor toolbar and paste in the text.

You will also need to provide the error message(s) in the same way.

Remember, you know what is going on but we don’t and we aren’t telepathic so “I get an error” is as good as “it doesn’t work” as an explanation of your problem.

Try fixing the code and we’ll see if someone can help you.

error massage is :
Error while running C/C++ Compiler

That‘s the entire error message?

 

UART1_SendData8("A");

I suspect it's becasuse the function is expecting a char not a string. So if you used 'A' rather than "A" it may compile. I'm looking at the documentation here

thank you. i changed the code and it worked.
