how to allocate large arrays in CCS

I don't think so. If I'm reading the manual correct that is too large for a single entity.

From the online help: A subscript to a RAM array must be at least 1 and not more than 128 elements. Note that large arrays might not fit in a bank. ROM arrays may not occupy more than 256 locations.

I read that as a big NO for your char array[512]

Thanks, Jim.

I guess I'll break it down into multiple smaller arrays.

I never really noticed the limitation before, so I leaned something too. I think the largest array I ever used in a PIC project was a 128 byte serial buffer. So, I never bumped into it.

I'm trying to construct a buffer to hold the contents of a Compact Flash read. The buffer is 512 bytes long. I'm using a PIC18LF2525, which in itself has plenty of data space (3986 bytes) but I didn't remember to consider page boundaries, etc.

I saw a FAQ in the databook concerning how to allocate table arrays up to

...I'm just getting old and blind...

Thanks

Using the CCS help that's in/available from the compiler, I did a search for "array". The best place to find it is in the error message listing. They have several array error messages and one of them has the text I posted.
