Hi,

please see the following. I edited LPUART example to able to use printf function. Do not forget printf is triggered by \n character.

Hi,

if you want use printf only for debug purposes - you can set I/O support to Debugger console during project creation. Printf output will be redirected to debugger console.

HI Jiri Kral

What if I have already created a project and now I want to enable debugging?

Hi,

you can switch the library with I/O support in existing project as well in project properties:

Hope it helps
