RHAPSODY4YOU

Hi all

I am trying to draw a model of an seat belt reminder system, which use a LIN bus protocol, sending a 40 bytes messages divided into five fields.
I would want to manage a LIN message with a bit-field structure.
I am a little bit confused, because on the Rational Rhapsody User Guide book I have read that RHapsody does not support C bit field, but I have also read here (unfortunatly I do not find the post more) that the strategy to create a bit field in Rhapsody is:
#1: create a new structure
#2: manually add the implementation using signature as:
unsigned int %s: <number_of_bits>
Auto-generating code Rhapsody substitutes by itself %s with the variable number.

I do not know what is the best solution, heeding the book or the post?
Any suggestion?
Thanks

Andrea

In Rhapsody In C++ there is a property called CPP_CG:Attribute:BitField

Allows you to define a bit field for an attribute. To define a bit field, open the Features dialog for the relevant attribute and enter the number you want to use for the bit field as the value of the property BitField.

For example, if you enter 2 as the value of BitField for an attribute named attribute_1 of type int, the resulting code is:

int attribute_1 : 2;
