Dear All,
Now I'm trying to use Hello example of cortex-m3 for study on KEIL (uVision)
I came across "retarget.c" when I was opening the project file.
Does anyone know what does regret.c work? Why do I need or use this file what for?
The retarget.c file is described in the manual: http://www.keil.com/pack/doc/compiler/RetargetIO/html/_retarget__overview.html
This file is part of the compiler pack (see http://www.keil.com/pack/doc/compiler/RetargetIO/html/variant__user.html). You can use it to redirect input and output to different displays, interfaces, File-Systems, debug output etc.
