Detailed Description

Minimal implementation of SystemSupport.h.

This implementation provides a fully functional implementation of all methods specified by SystemSupport.h.

The module maintains an internal buffer (with a configurable size) that stores on the "output". When full, the data is over-written. When System_flush() is called the characters in the internal buffer are "output" using the user configurable SysMin.outputFxn.

These functions are invoked by the System module. Application code does not directly call these functions.

#include <stdbool.h>
#include <stddef.h>
#include <stdint.h>

Typedef Documentation

§ SysMin_OutputFxn

typedef void(* SysMin_OutputFxn) (char *arg1, unsigned int arg2)

Output characters in the specified buffer.

The first parameter is a pointer to a buffer of characters to be output. The second parameter is the number of characters in the buffer to output.

This function may be called with 0 as the second parameter. In this case, the function should simply return.

Variable Documentation

§ SysMin_bufSize

const size_t SysMin_bufSize

Size (in MAUs) of the output.

An internal buffer of this size is allocated. All output is stored in this internal buffer.

If 0 is specified for the size, no buffer is created, all output is dropped, and SysMin_ready always returns false.

§ SysMin_flushAtExit

const bool SysMin_flushAtExit

Flush the internal buffer during System_exit() or System_abort().

If the application's target is a TI target, the internal buffer is flushed via the HOSTwrite function in the TI C Run Time Support (RTS) library.

If the application's target is not a TI target, the internal buffer is flushed to stdout via fwrite(..., stdout).

Setting this parameter to false reduces the footprint of the application at the expense of not getting output when the application ends via a System_exit(), System_abort(), exit() or abort().
