How can I establish what RAM I need...and therefore which PIC.

You can play around with Darrels CodeSize program to find some answers. I am not sure why, but it looks like each letter you are printing to your serial port is 3 words long. If you can abbreviate, you will be able to save some space.

I use MicroCode Studio Plus... I think it tells you the memory used in the Status Bar.

Where? I don't see it.

It tells you in the status bar, here. But you have to have it turned on with:

Define Measure 1

(and include the include file, of course)

Bottom left hand corner after you compile.

Success:blablabla bytes used.

Oh, there it is! That's telling you how much flash/program memory you're using, right? Is there a way to see or monitor your RAM useage?

That's right, its program data not RAM. Unfortunately I do not know of a clean way to read how much ram you are using. But someone taught me a trick of:

test var byte[96]

And if it is too big to fit, make it smaller. The size allowed in the program will be the amount of RAM you have left.

Talks about RAM.
I never did fix the little program in the thread though
