    A quick look at the datasheet doesn't mention anything about encoding, but it doesn't mention that it's required either?. It's possible that the module doesn't require NRZ (None Return to Zero) data signals?, and it does give suggestions about the construction of 'packets' to send through the system.

    You simply use a serial connection, I2C isn't relevent to this type of system.

    You can design a RAM7 board and burn Linux kernel into it.

    1) Linux Kernel support some webcam such as Webcam of Ov511 chip

    2)You can also cross compile an Open Source Video Server for RAM, The Video server have ability to send your video which is captured by your webcam to Upper computer

    3) you can cross compile an USB Wi-fi driver for ARM

    For simpler, You can chose a Wireless USB hub for your goal. Ultra-Wideband (UWB)Wireless Hub is a new technology of USB interface thch.

    you can get more info from:
    http://www.electro-tech-online.com/custompdfs/2007/08/060829.pdf



    Saitama, Japan, August, 29, 2006 -- Y-E DATA, Inc. (Headquarters: 182 Shinkoh, Irumashi,
    Saitama, representative director president, Mr.Kaneyuki Hamada) announced the
    development of ‘ UWB Wireless Hub, YD-300 ‘, in collaboration with Wisair. The ‘UWB
    Wireless Hub, YD-300 ’ will be available for the market in October, 2006.
    The YD-300 consists of a host-dongle and a wireless hub with 4 USB ports. It provides
    the wireless transmission of data between a PC and existing wired USB devices such as
    HDD, DVD, mouse, keyboard, printer, digital camera and so on. The YD-300, by
    eliminating cables, frees up space around the PC with wireless technology and ensures a
    comfortable environment for PC users. In addition, this solution enables a wireless portreplicater
    with ease for notebook-type PC.

    Key Features
    Up to 480 Mbps air data rates
    Up to 10 meters operating distance
    Compatible with Windows XP
    4 USB port hub
    Host Dongle: 29.8(W), 96.2(D), 9.4(H) mm
    Hub: 103(W), 79.5(D), 19(H) mm
    NewsRelease
    Y-E Data Inc.
    182 Shinkou Iruma Saitama Japan
    In the near future, Y-E DATA will provide solutions with the ‘Certified Wireless USB’
    technology of USB Implementers Forum, Inc., as well as PCI Express interface solutions.
    These will include, for instance, an ExpressCard/34 host card and PCI Express Mini Card,
    to expand the possibilities of wireless technology.

    sorry, I'm late to the party!

    The goal - transmit video wireless from robot to remote laptop?

    The solution - 802.11b camera:

    http://www.trendnet.com/en/products/TV-IP100W.htm

    that one is about "middle of the road" for features and pricing.

    you'll need 802.11b/g on your laptop, and will probably need to setup the camera via wired connection first, but then it should stay configured, ready to go on adventures with the robot. it only needs 5vdc, which any good microcontroller powered robot should have in abundance right?

    the thing to look for if you decide to purchase on of these - make sure it supports ADHOC networking, so you don't have to lug along a wireless access point if you go out in the field. I like this model because it has an external antenna, which you can replace with something more powerful.

    EDIT:

    oh, just re-read the original message, you want RX and TX ... well, sending video is a lot harder than sending telemetry. Does your laptop have bluetooth? You could use a bluetooth serial module to carry the telemetry, or any of the other small serial data radio modules. Even 9600 baud can carry a lot of data. If your hacking skills are good, you might be able to tap into the camera's software and processor some how. The wifi camera's processor probably has some sort of uart interface in it - exposing the correct pins should be a matter of some data sheet digging, exposing it in software will be the challenge. Others may have hacked a wifi camera already, laying the groundwork for you.

    oh my, well not too relevant anymore I suppose ;)

    guess I didn't notice the time stamp on the original posts, just the latest posts from the newbies.

    Threads from the crypt.

    I often read the ancient threads and when the reality/complexity/cost of the project becomes clear... Poof end of thread.
