Hi,
My boss ask me a question and I have no idea how to answer,
my boss ask, "Can Stamp try to control·cdrom/dvdrom drive ??"

as I know, the communication of optical drive is·IDE/USB interface.
so,·it·seems is hard to·reach the target ...

    1. A BS2 has a total of 26 bytes of RAM. That's not going very far in a CDROM.

    2. A BS2 runs at about 2,000 Basic Instructions Per Second. That's pretty slow for a CDROM.

    3. There DOES exist an IDE interface for a BS2. However, it's slow, and you're still gonna need someplace to put all the data flooding off the CDROM.

    4. It is remotely possible that a BS2 could be used as a 'keypad' for a CDROM music player. But that will take more hardware than just a BOE, CD-IDE interface, and CDROM player.

    I know this is for the basic stamp, but could other parallax processors do this?

    The SX48 or SX52 is a very capable, 50 MIPS processor. You can program it with SX/Key and get a 'basic' environment for it. The big question you still haven't answered is -- "control the CDROM to do what?"

    If the answer is "press a 'play' button", then yes the BS2 can do that. If the answer is "read the data coming off the CDROM and turn it back into music and play it on an attached speaker" -- an SX52 MIGHT be able to do that, but it would take a LOT of programming.

    Thanks, I wasn't looking for it to do anything specifically, I was just curious if you could interface the two.

    D Faust -

    You could probably open the tray fairly easily, but that's about it. I must say I've not tried to do that, however.

    Regards,

    Boy, if anybody does THAT with an SX protoboard, congratulations on the new job at Parallax!
