Does anyone really use MMC cards alot?

I'm considering droping support for MMC cards from my file system driver (they don't work that well with my code anyways).

Would this be a problem for anyone? You really can't buy them anymore anyway and the new versions do not support the SPI bus so they do not work with simple embedded systems.

I know people have old MMC cards. But, if you're buying some new prop equipment shelling out an extra $10 bucks for a SD card is not alot.

    Kye,

    I'm pretty sure I don't own a MMC card. It's fine with me if you drop support for them.

    This might be a good thread to use the "poll" feature of this newer forum software.

    Without support, in your software, I could convince myself to finally throw them away. I think that the biggest one I have is 32MB.

    (being anchient means that I thought that 40KB on a Floppy was good)

    What is a 'MMC' card?

    Seriously, yes, you can drop the code and save some space. One or two Gig on an sd card is now the optimum price/memory point.

    I have several.. 16mb.. and still would probably never use them.. Dump the code and open the space for better things.

    Yeah, I'm thinking they are dead now.

    I agree with the consensus so far. I don't think it's a problem to drop them.

    I have a couple around somewhere, but I have no idea where they are. One of them is probably stuck in a very old Creative mp3 player, but I have no clue where it is either.

    What is an MMC card?

    Sounds like yet another example of technology that has come and gone without me noticing. Like the VCR before it.

    Hi Kye.

    I don't think them are dead -- As I have one PDA device that still use them --> But for Prop not so usable as in Sweden them are no longer in stock. Old technology before SD specification become accepted by all Factory's.

    I still have a couple of MMC cards. I don't believe they'll ever completely die, any more than model T cars or vinyl records.

    But you're right; they're ancient history. My suggestion would be to drop support in your current development, and those who want to save and use old MMC hardware can themselves save and use old software that does support MMC.

    I agree with OBC, drop support for MMC and free up some extra PASM code space especially if lack of extra code space is stifling improvements/fixes.

    Yeah, I really could use more PASM code space. The cog is 100% full.

    see it this way:
    we have your "legacy" objects, so MMC is not doomed... it will simply be left a little bit behind.

    I used to have boxes of chad from punched cards and punched paper tape. Do they count? But they are no longer permitted for weddings as it is not considered green anymore.

    No, seriously Kye, reclaim the space. You older code remains for anyone, just in case.

    BTW If you require extra code space, you could use my overlay code in the obex for small, less used sections.

    You never noticed the VCR? What were you using during that era when recordable DVDs were not available, Eight-Track Tape?

    Humanoid,

    Well, OK, I did notice the VCR. Never bought one, never had the urge to buy one. Never had the urge to record anything. Never had the urge to rent a movie.
    Now we have recordable DVD, same applies.

    I did once have an Eight-Track in my possession for some long forgotten reason, never used it. They were pretty much obsolete at that time.

    Perhaps I'm odd. I've never bought a TV either. Lived for over a decade without one in the house. Seems women have to bring them along though:)

    Definitely ditch MMC, apart from anything else even if someone does have a few if they die they are pretty stuck and SD is so cheap that there is really no issue upgrading. Anyone who really needs MMC to interface with some other old technology can use older revisions.

    You left out 8-Track tapes. Not that I miss them (visions of seemingly miles of tape stuck in the player). :smile:

    And I don't have any MMC cards, so I vote to use the space for other features.
