Assembler simulator & flags

Hello,

My propellers did not arrive yet and I have a couple of questions:

I wanted to know _were_ are the C and Z flags in a COG, they seem not to be part of the RAM.

Anybody know if an assembler simulator for the Propeller exists, or how are we supposed to debug the asm part (try & error in hw ?)

Thanks !, I'm looking forward to work with the propeller !

    1) The C and Z flags are part of the logic of the arithmetic unit of the cog and don't appear in RAM

    2) Look at GEAR (http://forums.parallax.com/showthread.php?p=624986) for a simulator

    3) Look at POD (http://forums.parallax.com/showthread.php?p=639020) for a debugging tool

    4) There are several "sticky threads" that always stay at the top of the list of discussion threads for this Propeller Chip forum
    They have lots of good information about both Spin and Assembly programming and a thread index for various topics.

    Thanks Mike,

    I searched the forums with "simulator" and "emulator" without results, so I asked.

    Yeah, the search mechanism often isn't very useful. Use search.parallax.com which uses a Google search engine, but is hosted at Parallax and just searches the Parallax website.
