Help wanted for top secret project

Posted by Jordi Muñoz on January 2, 2011 at 5:00pm

Happy new year folks!

3689383891?profile=original

DIYdrones hardware development team needs some help, if you think you can contribute in something please PM, our requirements are:

-Any microcontroller capable to handle a little web server can be used.

-The hardware must have WiFi access (behave as an access point).

-The hardware must have SD card slot (where you can store html files).

-Must be cheap (< $100).

 

The system must be capable to read a HTML file stored on the SD card (including pictures) and create a web server accessible via WiFi (acting as an access point). When the user is connected to the Wifi device-must type any direction like "http://192.168.1.100" and be able to load the HTML files stored on the SD. Something similar to a home router.

 

The HTML files must be able to read/write to the IO, analog and UART pins of the same microcontroller....

 

What we need from you are suggestions of the right hardware, software contributions and connections to anybody capable to help us.

 

Anyone? ;-)

    A +18dbm version is only $38.xx and the programmer is $149.

    Add a small bidirectional amp for ~$50 and this could be a viable thing.

    Not everyone needs the programmer. Once the program is developed, it can be uploaded by ttl 5v signals from what I read.

    +18 dbm is over 50mw which is quite a bit of power.

    Does this module support AP mode? Or just Client?

    @medaidroid FPV systems frequently use directional receiving antennas that need to be aligned to the transmitter.

    @bGatti not much like an Arduino, no.  The G2 SoC uses a SPARC core, and the runtime (eCos) is a realtime operating system.  That being said, what I can see of the documentation looks like fun...

    @Lew nice, but $2500.  Not so good for DIYing (but quite possibly fine for this application).

    Note it's GCC, so it would feel a great deal like Atmel/Arduino?

    this WiFly module include 8Mbit of Flash

    http://www.rovingnetworks.com/documents/rn-171-ds.pdf

    Which means - in a single part - WiFi, MCU & Flash

    Web site confirms that user Firmware is an option:

     

     

    Writing your own Firmware

     

    RN-G2DK  

    RN-G2DK

    • The RN-G2DK allows users to quickly develop applications for teh RN-131 module by modifying code from comprehensive example library
    • The SDK produces executable code that can access all WiFi resources
    • Based on GCC, GNU make and the LEON BCC compiler system
    • Epsilon ROM includes eCos, TCP/IP stack and 802.11i security functions
    • Single or multi-threaded capibility

    WiFly was actually mentioned pages ago.

    For me, since the WiFly includes a 32 bit mcu  it seems redundant to mate it to an Atmel.

    Is there no hope of writing the PWM routines to the WiFly mcu?

    WiFly... "writing your own firmware" development kits available.  Note that Mouser has then for less, and Roving Networks has a good page showing the available versions.  Indeed, an excellent find by bGatti.

    Here is another hardware suggestion, just needs a wifi module http://www.littlebirdelectronics.com/products/%5BBeta%5D-Netduino-P...

    Programing in .net, 32 bit Atmel cpu.
