I'm building a project with tiny library C_4i_CF_SZ.a
I want to use printf to write on my LCD display.
My routines are ok and tested. What I want to do is to redirect the printf to my proprietary function that use my GUI.
As usual I tryed to redirect the stdout->write_proc to my function Write_Display.
I debugged my code and I'm sure that the correct address is filled in the right position of stdout structure, but when I use printf and fflush functions my proprietary function is not colled.
Where is my error??
Thanks for your support
