Application Note
AT32 Printf Debug Demo
Introduction
It is common for the user to check the debug process information in the process of application code
debug. In most cases, this action can be done through the serial port debugging assistant.
However, it would be a headache for users to try to observe the testing process information when
the serial port assistant is not supported by the hardware.
To address the above concerns, this application note provides a complete set of example codes
describing how to output the debug process information, especially when the serial port debugging
assistant is not available.
