Hello, I've open this new topic because I'm having problems trying to use the printf() and printf_P() function in my project's serial communication.
I'm using an atmega88pa, I've tried with the examples in the avrlibc page, and some from this forum, and got nothing.
The serial communication it's working fine, I can send and receive characters, I can send string chars too, with a puts function that I made.
I'm going crazy with this, if someone can help me I will totally grateful.
P.S.: I apologize if it's not the correct subforum for this question, and for my english =).
P.S.2: I attached the code that I'm using to do the tests
