    Default USB memory stick

    Hi,

    This is a suggestion for those that like to post samples projects and are in the middle of the USB bug (...waves to Bruce... ).

    How to connect a USB virtual drive to a PIC 18F4550?

    I'm starting to hit the space capacity of the Atmel series of EEPROM chips. I need over 1 meg of storage for my application and the AT24C1024 is becoming tedious to manage. Having to split the data between 8 ICs is something of a pain.

    The great thing with using a USB stick is the easy of expansion. I was considering the SD compact flash cards, but since I'm in the middle of adding USB to my project, I figure, what's another USB I/O?

    When you compare the price of the Atmel chips with the USB sticks, USB comes out miles ahead.

    I was considering the SD before because of the high capacity, available circuitry and ability to be read from Windows Explorer. The down side is that it requires a special reader to be connected to the PC. The USB stick can be swapped between PC and project at will.

    (..I feel like a lobbyist scurrying around parliament...)

    I sure hope so. I'd be disappointed if the PIC only supports PIC-PC USB communication.

    If the PIC has true USB capability I don't see why it can't talk to a USB memory stick, unless it only has a subset of the required code.

    But you're right, it's possible it can't. There's no mention whether it can or cannot act as a host. I'm really hoping for one of the powers-that-are to step in, slap me silly and settle the matter.

    The PIC can be configured as a USB 'peripheral' device, but not as a USB host device.

    Check out USBWiz in this thread http://www.picbasic.co.uk/forum/showthread.php?t=1888


    Don't think it's available yet, but looks like it will make life a lot easier for us.

    Thanks David, not I wanted to hear, but at least now we know for sure.

    I guess it's back to the SD card then.

    I'm kinda interested in HIDMaker FS:
    http://www.tracesystemsinc.com/usb_tools.ivnu

    ----------------------------------------
    Not merely a function library that you have to figure out: HIDmaker FS generates complete, fully functional programs, for both PC and PIC, that you can just compile and run in minutes!

    Full speed 18F4550 family:
    - MPASM
    - PicBasic Pro

    Low speed 16C765 family:
    - PicBasic Pro
    - MPASM

    Can create standard USB HID devices (e.g. keyboards, mice, joysticks) that can be read directly by Windows. Can automatically create special devices, too:
    - Devices with multiple USB Interfaces.
    - Soft Detach Devices with multiple personalities
    ----------------------------------------

    A tad expensive though, $599 USD. But if the software does as much as it claims, it seems rather interesting.

    shipping is ONLY $15 USD

    So in Total ONLY $19.99 USD

    I guess you missed to read the smallprint.

    Talking Mecanique Version of HIDMaker

    Hi,

    Mecanique makes a totally free version of HidMaker.
    They call it "EasyHID" and it works with PicBasic Pro and Proton (PDS).

    http://www.mecanique.co.uk/products/usb/easyhid.html

    It generates both the PIC and the PC code for either VC++, VB6, or Delphi (whatever you choose).

    So, save your money!



    Cheers!

    So that doesn't fix the problem at all. Flash card will be the way to go i guess.

    It's not a bug, it's a random feature.
    There's no problem, only learning opportunities.

    Hi,

    Yeah, I know.
    I just thought I'd mention it though, since somebody mentioned something similar that cost $599. I know that you need Microcode Studio to use it, but that is still a far cry from $599. MCS is worth the money even without EasyHID.

    Thanks for the remainder Picnaut

    Since USB HIDMakers softwares and USB PIC are still a new area for many here, we will see many question in a few.

    Oh yeah i agree 100% For bootloader, serial communicator and the list is still long. I can't live without bootloader now, even if ICSP also do the job as well.

    Now, that's cool!

    This is definitely the way to go!
