printf redirection

[mircopizzichini]

Hi all

Currently I'm porting my old MQX project on KSDK.

In the previous version, we had modified fio.h file from:

#define  ioctl      _io_ioctl  #define  printf     _io_printf #define  putc       _io_fputc

to:

#define  ioctl      _io_ioctl  #if defined(MQX_USES_MY_PRINTF) && MQX_USES_MY_PRINTF == 1    #define  printf     my_printf #else    #define  printf     _io_printf #endif #define  putc       _io_fputc

where MQX_USES_MY_PRINTF was defined in user_config.h.

This is beacuse we used a custom printf function which, in addition to performing the classic _io_printf, sent the string to the Bluetooth_Task for wireless transmission. Now fio.h file is no more present.

Is there a way to replicate this redirection? The new function shall be called by EVERY printf in my working set, like usb or nshell project.

Hi,

You may find similar definition in the following header file:

Hope that helps,

Have a great day,
