Does anyone have some good ideas, doc's or samples that show more automatic ways of getting the most out of the memory layout of the SX chips? Or the PIC 16C5x chips? I'm looking at using macros to re-org and compile jump tables and other things that use a relative or computed jumps or calls (including all subroutine entries) in a reserved chunk of "first half of page" memory. Seems like a hell of a waste. Ideally I'd like to find and document on the site the "best" layout of memory in general (to support interrupts, debugging, subroutine placement and calls, etc...) without having to shuffle things 500,000 times after each code addition that over-runs the available "first half of page" space or violates some other memory layout rule or .... BTW, if you haven't seen the exhaustive "how to do a comparison" table at http://www.sxlist.com/../scenix/lib/flow/compcon_sx.htm and the SXKey Structured Programming macros built from it at http://www.sxlist.com/techref/default.asp?url=scenix/keymacs.src you might want to check it out. This version is much more stable than the last. My testing hasn't found any bugs in a while so they may just work for you! --- James Newton 1-619-652-0593 mailto:jamesnewton@sxlist.com SX FAQ: http://www.sxlist.com or .org -- http://www.piclist.com#nomail Going offline?
