Keep in mind that it is good to set your locale for messages to some English locale, because C::B parses strings using regular expressions. If the parsing fails this might hide important messages from you.
And also the chance for a useful answer will raise, because more people understand English than the random language you might be using. (I'm also not a native English speaker).
But I take the two files in my archives, and put it in the folder obj/Release and it's good.
I don't know why, but every time I rebuild the project, the obj/Released files are deleted.
I'm not sure I understand what you're doing, but one thing is clear you're doing something you're not supposed to.
The files in the obj folder are managed by CodeBlocks, so when you do a Rebuild it deletes them.
They are supposed to be produced by the compiler during the build process.
If they are not there after the compiler has run then something is broken.
Try to run the commands in a terminal and see which one fails!
This might give you clues what is going on...
the must weird thing is, when I delete the build, and I rebuild it, CodeBlocks make a new bin file, and this one call ttyACM0, but I modify the code with the new serial port (ttyUSB0). I already save the update. I have no more ttyACM0 informations on my code... I don't understand
No idea what you're talking about, but this has nothing to do with CodeBlocks...
