Dear Genius!

If you have any idea how can I connect for example one wifi SD card to propeller and
how can I transfer some bytes to PC and from PC please write me here.

Thank you.

    Are you asking somebody to develop the project for you?

    If you are asking about the WiFi interface cards that are made in an SD card form factor like the one sold by PalmOne, there is no existing software that would allow you to use it with a Propeller. The existing SD card software is for memory cards only, not I/O cards.

    There are some WiFi interfaces, for example the WiPort made by Lantronix, that can be used with the Propeller. You can also use Parallax's memory stick data logger to transfer files back and forth with a PC using a standard USB flash memory stick. There's Rokicki's SD Card I/O routines that will read and write PC compatible files as long as there's only a root directory (the routines ignore any subdirectories).

    You might also like to take a look at the DPAC Technologies 'Airbourne' WiFi products (http://www.sssplc.com/store/index.php?act=viewCat&catId=7).

    UART / Digital I/O / Analogue Embedded Wireless (802.11b) Bridge.
    Product Code:- WLNB-AN-DP101-G
    Product Information

    The Airborne embedded module features a fully intergrated 802.11 radio and network processor that provides a complete wireless network connection in a single, small footprint package. Airborne wireless modules provide all of the network protocols and processing needed to implement embedded wireless solutions. They offer industrial-grade performance, making them ideally suited to harsh environments.

    Sparkfun also sell these, along with a breakout board.

    HTH.

    You'll always have as many take-offs as landings, the trick is to be sure you can take-off again ;-)

    Yes good idea, but the price is so high of this moduls. I have two price quotation from hungarian distributors like:
    WP2001000-02 WiPort about 168 EUR
    DC-WME-01T-S DIGI about 270 EUR
    Any other WIFI CF or SD card's price is no more than 80 EUR

    yeah...who wants to spend $125 to add wireless capability to a $13 Propeller?

    @ Neo2a : If you don't actually need Wi-Fi there are cheaper alternatives for wireless communications from a Propeller and PC, of particular note is the XBee product from MaxStream.

    It is good solution, but the wifi network already intalled that area where I want to use this.

    Hi Ken,

    Yup, I agree; but it depends if you have any choice!

    If the application requires WiFi; if the Prop' can't do it itself (I'd like to see me proven wrong!), and the solution you're designing warrants the cost, then that's the price you'll have to pay cry.gif

    You could use a PINK module with a WIFI -> Ethernet bridge

    A related problem to using a SD Wifi card is not just the 'driver', but the fact that an IP stack would be required. I do not think you could create a SD-Wifi driver AND tcp/ip stack AND have enough memory left over to do anything useful.

    The propeller is neat but lacking in memory for anything big and complex.

    I wonder if someone sells a product that will do serial over wifi.

    Lantronix makes a variety of WiFi interfaces that talk via serial to a microcontroller. Have a look.
