Data was shifted when i use UART


Recommended Posts

Hi everyone,

I make a GUI and send a string contains 4 bits,

The first time i send ( E.g "1234") I have received "1234"

But the 2nd i have received "2341", so on the third i have received "3412"

So data was shifted, I have debugged and detected in my received string have a char with value ="10" (LF), Although i havent send it.

How can i fix my error?

Plz give a solution, thank in advance.

1) Welcome

2) What does your code look like?

3) What language did you use to build your GUI?

4) Your string contains 5 bytes.

 

The 10/LF is the line-feed control character and is sent as the result of either:

- pressing enter, which might be contained in the sent string

- using a println() or writeln() or similar function to send your string, in this case use print() or write() or similar instead

- adding a \n in the sent string ("1234\n" instead of "1234")
