Are there any plans to putting together a prop object to support this device?

    Hi, EveryOne



    Yes i would like to know if there are any plans to have an prop object·for the· Parallax GPS Receiver Module

    I don't know about this particular version, but I'm about to buy the 20 channel version of this GPS and interface with it using the Propeller. I think it will use the same protocall. So you may be able to use my object when it is done.

    But be warned.....it took me a week to talk to a MAX 1202. I had help from three people to get there. So it may take some time.

    Almost all GPS receivers (I have a couple) talk the standard NMEA serial protocol (plus a binary propietary protocol sometimes. It appears NMEA is sort of lax protocol in some aspects but at least it's pretty universal and there's ton of info and code for parsing it. Procyon's Avrlib, (a free & libre) set of C libraries for AVRs) has some code to parse it.

    I looked at the docs for the Parallax GPS module and it has a "smart" mode, (aside from raw NMEA mode) where you can just ask for a specific piece of data with a couple of bytes, and it'll send it to you. This means you don't have to do any parsing, so it shouldn't be hard.

    Hello Everyone,
    The GPS module will be used in the Propeller Book I'm working on for Parallax. In fact most all of the sensors offered will be used in some very interesting projects that are unique. I'm currently working on the layout and order of topics. I want it to complement the existing manual as much as possible. I've done some extensive work in the beginning of the book on the math capabilities of the part. Look for a couple of pretty neat applications using the GPS module and the small NTSC Audio Visual display. There will also be a chapter or two on how to migrate from the BASIC Stamp or SX to the Propeller. So hang in there for a few months and I'm sure you will find it worthwhile.

    Hi Oliver,

    What will be the title of the new text your working on (so I know what to look for)?

    Regards,

    Oliver,
    in your GPS chapters/examples, will you be covering navigation using GPS module. Specifically route and route points?

    Would you have this book in eBook format also?

    thanks, Nagi

    Hi Oliver,

    I have not yet purchased the Propeller chip (I am just a newbie)·but I do see alot of potential for use in UAV and other unmanned vehicle systems.· My upcoming UAV project will require the use of GPS, compass, accelerometers, range finders, servos, barometer(?),·etc.· I will also need to maintain an RF link with a high-range radio modem such as the Maxstream XTend·or XStream (http://www.maxstream.net/products/).·The RF·link·from UAV to ground station·will allow for two-way communication between UAV and groundstation.· Telemetry data will be downloaded live·for assessment and possibly retasking from the groundstation.··Could you cover installation of an RF modem·(preferably MaxStream) in your book?·What about servos?

    Thanks,

    Brian J

    Hello,
    I am sorry it has taken me so long to respond but I've been busy with the Propeller book and the finishing touches on a book just going to print. I see that have been three posts about covering the GPS module in the the Propeller text so lat me make a general statement. The project that I am working on covers navigation in a limited fashion. It's not going to compete with the Garamon GPS module as it is intended to both educate on the Propeller and the GPS unit communications. Keep in mind that I could do a book the size of an encyopedia, that people would use to elevate their notebook screen or a smaller book that people will really read. Personally, I think books over 250-300 pages are to long to keep the readers interest on technical subjects.
    As for the title, it is yet undetermined. The page count will be between 200 and 300 pages. This is a beginners book to get them comfortable with the Propeller, COGS, Multiple Processors, SPIN and Assembler, and how to move from the Basic Stamp and SX to the Propeller. I'm doing that through the use of Parallax peripherals and hands on projects. That's a lot to accomplish and still keep the text short enough to be interesting. That means that topics like ZigBee probably won't get covered or will be minimally covered at best. I hope this addresses your questions and again I apologize for taking so long to respond.

    Regards,
    Oliver

    We're building a Prop-based UAV and using a garmin etrex right now (because the simple text format outputs once per second rather than once every 2 seconds like most nmea devices). The parallax gps would be nice to have in that it's smaller and weighs less.... does anyone have a use for our stuff so far? if so, email dhatch@stmarytx.edu

    MK Borri,
    when you say, "does anyone have a use for our stuff so far?", what are you offering here. I am getting ready to buying Parallax's GPS Module and I will be using that in my autonomous land robot - ALIBE.

    I am hoping to use Prop to determine 1) gather NMEA lat/long/speed/alt 2) use it in way and waypoint navigation 3) take the robot from A->B. I was looking for some guidance on how one might use Parallax GPS in this application.
