32.1.1 Application Input/Output with printf() and scanf()

Many PIC32 devices support the APPIN/APPOUT debugging feature. This PIC32 feature allows the PIC32 application to write text or data to an MPLAB IDE window, invoked from the Tools menu, without halting the target device. Similarly, you may use the display window to send text or data back to the target PIC32 device. This feature requires an MPLAB REAL ICE emulator or MPLAB ICD 4 debugger.
