Interfaces Target

In each Code Composer project which results in an application, there are some extra target dependant files which you use. These usually come with an evaluation board. The startup file and DSP/BIOS configuration file can be copied from an example by Texas Instruments when you create a new project.
The example which is part of your product release is suitable for a eZdsp F28335 Evaluation Board.

To interface with an TMS320 C28XX 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.

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: void WSTTarget_enterCriticalRegion( void );
WSTTarget_exitCriticalRegion	Its prototype is: void WSTTarget_exitCriticalRegion( void );
WSTTarget_timerInterrupt	This function is added as wrapper to WSTRTOS_incrementRxfTicks() Its prototype is: void WSTTarget_timerInterrupt( void );

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 a disable of global interrupts and higher priority debug events
WSTTarget_exitCriticalRegion	This function is implemented as an enable of global interrupts and higher priority debug events
WSTTarget_timerInterrupt	This function serves as wrapper to WSTRTOS_incrementRxfTicks() and disables/enables the global interrupt INTM and global realtime interrupt DBGM.
