CCS Packed Data Structure Support for MSP430

Hi everyone,


I just inherited some code that we want to run on an MSP430. In particular, the code is an E!A485 based communications application which has a large number of data structures which define the packets. As with all communications protocols, this one does not allow padding in the data packets. As far as I can tell, Code Composer Studio support for MSP430 does not include packed data structures, not even the latest release of CSS seems to have this feature.


The project deadline is 12-17-10, and without packed data structures, we will have to use a different chip (non-TI) or a different IDE for the MSP430, if one exists which has support for the packed data structure. Just so you know, anyone who is concerned about the readability of a communications based application will not use any of the TI parts for that purpose which do not support packed data structures.


Anyhow, I guess that Im out of luck as far as CCS is concerned - are there any other 3rd party development environments out there which would allow us to use the MSP430 for this communications based project (we don't have the time to re-write the code to get rid of the data structures, and even if we did, that would not be an option for us) ?

I made the mistake of assuming that CSS's MSP430 C compiler would support packed data structures, as I have never seen a compiler before that did not support them, except for one TI DSP compiler a number of years back, so a fast response to this question would be greatly appreciated as I am holding back progress on this project as a result.
