SRV-1 WiFi Module and SRV-1 firmware update (srv-041507)

The SRV-1 WiFi Module can now be ordered, though we are still waiting for voltage regulators to arrive, so shipments might be delayed a week. The link for ordering is found here.



Note that there is a special limited time offer for users who already have an SRV-1 and a WiPort module and just wish to order the WiFi module circuit board - contact us via email (support@surveyor.com) for order instructions.

Setup instructions for the SRV-1 WiFi module have been posted here - Lantronix WiPort Setup for Surveyor SRV-1



A firmware update has also been posted. Besides support for the WiPort at 921kbps, we've also fixed the issue with camera timeout after the "zw" command or C/BASIC programs that don't use imgcap(), as well as the improved IR sensor support that was previously discussed. Here are the details (also found on the software download page).
  • srv1.hex.041507c w/C interpreter - last updated April 15, 2007 (rename to srv1.hex)
  • srv1.hex.041507b w/BASIC interpreter - last updated April 15, 2007 (rename to srv1.hex)
  • srv1.hex.041507w for WiPort w/C interpreter - last updated April 15, 2007 (rename to srv1.hex)

    The following additions and changes are included in this release:
    • support for 640x480 capture resolution - 'A' command ('d' was already taken)
    • support for WiPort at 921kbps with CTS/RTS flow control
    • fix for camera timeout after using "zw" or running C/BASIC programs (restarts camera within 5 seconds)
    • improved IR sensor support - much better sensitivity and directionality as a result of software changes
    • addition of 2 image processing functions
      • 'vf' - finds first occurrence of specified color in each pixel column (corollary to 'vs' scan function which finds first mismatch of specified color in each pixel column)
      • 'vn' - counts the number of occurrences of a specified color in each pixel column
    • elimination of the 'm' function - the vision functions are no longer modal, and 160x128 frames will always be decompressed into YUV
    • elimination of 'l' and 'L' locate beacon commands
    • elimination of 'x' and 'X' xmit beacon commands

Changes to the firmware are reflected in the latest SRV Protocol Definition
