I think you are better off not to try and fight the size limits,
and just use a different chip. But for myself, often once you know a
chip and its development tools, it's not easy to switch...
I've had to remove some features to fit my code into 8k of x1232,
and always keep bumping into the limit,
and as I asked early, reworking to prevent stack overflow in 256 bytes
of RAM... I'd use a bigger 430 if handsoldering of the QFP format was
easier.
It might be effective to use a simple compression algorithm on the
strings, and then uncompress them as needed into ram. I know that
in one of my applications, just using 6-bits instead of 8-bits for
alphanumerics will save a lot of space. In another application, I
compressed the code using a simple statically-determined lookup table
for decompression, making the decompression code very small and simple.
In that case, though, it had a lot of ram to decompress the flash into.

Hello,
Is it possible to use external memory (ROM, RAM, FLASH) with the msp430
which holds executable program instructions? So it is possible to make
programs which are bigger than 60KByte?
I know that the answer is 'No'. But does anyone have a creative solution.
We have applications which extend the 60KByte program code. A big part of
the code is text string, which are used by the menu user interface.
Currently we are using de intel C196 processor for these applications. The
C196 can use external memory. And program code is in a page switching flash
memory. The C196 is getting obsolete. So we are looking to alternatives. We
uses the MSP430F149 is used in a number of (smaller) projects.
Of course it is possible to use another processor. Should we?
Or is there a way to still use the MSP.
Thanks Robert Bon.
