C166: USING SOF FOR PEC IN EMBEDDED C++

Information in this article applies to:

• EC166 All Versions

QUESTION

While using the Embedded C++ compiler, if I initialize a PEC pointer using the _sof_ intrinsic function, I get the following error and warning messages:

unsigned int sdata samples[70];

 SRCP0 = (unsigned int)&ADC_DAT;
   warning 174: conversion from pointer to smaller integer
   warning 174: integer conversion resulted in truncation
 DSTP0 = _sof_(samples);
   error 176: argument of type "unsigned int sdata
              *" is incompatible with parameter of type "void huge *"

Is there a way to remove these error and warning messages?

ANSWER

Yes, you may use type casts as shown below:

  SRCP0 = _sof_ ((void huge *) &ADC_DAT);
  DSTP0 = _sof_ ((void huge *) samples);
