Interfaces Target

In each MPLAB project which results in an application, there are some extra target dependant files which you use. These usually come with an evaluation board. The example which is part of your product release is suitable for a Microchip PIC32 Starter Kit.

To interface with an ? target, the files WSTTarget.h and WSTTarget.c have been implemented as follows:

Files

Description

WSTTarget.h

This file defines the following constant if the constant WST_RTOS_NONE is set,

RIC_MS_PER_TICK	This constant defaults to 10. Please refer to a section on Porting to a Target to see if this value is correct for your hardware or details on your Board Support Package, if any.
WST_TARGET_SAVEISRMASK	For some compilers, one must restore a mask instead of enabling interrupts after a disable.

This file defines prototypes for the following functions:

WSTTarget_Init	Its prototype is: void WSTTarget_Init( void );
WSTTarget_Cleanup	Its prototype is: void WSTTarget_Cleanup( void );

This file defines prototypes for the following functions if the constant WST_RTOS_NONE is set:

WSTTarget_enterCriticalRegion	Its prototype is: isrmask_t WSTTarget_enterCriticalRegion( void );
WSTTarget_exitCriticalRegion	Its prototype is: void WSTTarget_exitCriticalRegion( isrmask_t status );

WSTTarget.c

This file implements the following functions:

WSTTarget_Init	If WST_RTOS_NONE is set, this function initializes the timer and inserts WSTTarget_timerInterrupt as ISR.
WSTTarget_Cleanup	This function is left empty.

This file also implements the following functions if the constant WST_RTOS_NONE is set:

WSTTarget_enterCriticalRegion	This function is implemented as INTDisableInterrupts()
WSTTarget_exitCriticalRegion	This function is implemented as INTRestoreInterrupts()
CoreTimerHandler	This __ISR function clears the interrupt flag, updates the core timer and calls WSTRTOS_incrementRxfTicks().
