Re: New RCtimer GPS Ublox Neo 6M fails to perform on Mega bo

Hey guys. I just found out that the battery on my Ublox Neo 6M was ripped off, and one of the traces broke. I appear to still be picking up sat's, and I am curious if I can just remove the battery from this board without doing any harm?? I am running 2.2pre on my 2650 Mega Board. I've been there......

Re: Release 2.2 is coming

BTW, I think one change that should be made for owners of UBlox GPS's that don't reside in Europe is to enable SBAS support for all locations and not just the EGNOS system. The PRN sat bit fields should all be set to zero's (all SBAS satellites) instead of the EGNOS only satellites in the UBLOX bina...

Alright, I answered my own question. :) Short answer is no...

Long answer is to windiff it and change the couple of differences.

Re: wishlist for v2.2

Here's a trivial to implement feature request:

Re: MultiWii EZ-GUI

Quick question:

If I run calibrate acc or mag, do I then need to save the results into eeprom? Or are they automatically saved?

There would not be any sense on using GPS height, once because it is not so accurate and second, when you would modify config.h, you should know the exact place where you will fly after...

Re: Altitude Hold/Advanced Failsafe solutions by NHA

I apologize if this has been answered before...

The altitudes like RTH_ALT are they absolute heights based on the GPS or are they relative to the altitude that arming takes place?

Oh and majoo reminded me I forgot to tell you this: (Add the red lines to multiwii.ino right after the #if defined (GPS_SERIAL)...) Remember, this procedure is only valid for Multiwii 2.1. The development code version of Multiwii is setup up differently. Plus add the initialisation to the main file ...

Re: GPS integration

Vin, I watched your video again, you do have the gps connect to your serial ports. (Not the i2c port) That's good! The video is too blurry to tell how it's wired. You obviously have vcc and gnd wired correctly (gps green light). I can't tell if the tx, rx ports are hooked right. I would take it outs...

Re: GPS integration

EOSBandi - On your above recommendation, I upgraded my multiwii software from 2.1 to the current development version. I noticed that the gps.ino file is configured for Europe and EGNOS. I updated the U-BLOX config code to support US and WAAS. I basically commented out the EGNOS line and added the eq...

Re: GPS integration

Okay, this is my fault. I was assuming you were using a normal serial port and not an i2c port. I missed that important detail. So my above instructions won't work. I'm not familiar with connecting a gps to your i2c port. You may (I don't really know) need this board: http://rctimer.com/index.php?gO...

I would have used the gps file on page 7 from quadwalker.. But the one you grabbed should be okay.

It looks good. Good luck.

You need to use the gps.ino file found in the above thread that I linked. Ideally quadwalker's version.

Yes. This is assuming that you are using quadwalker's gps.ino file.

Re: New RCtimer GPS Ublox Neo 6M fails to perform on Mega bo

My default connection speed is 38400 baud and not like others with 9600 baud. Do you think the solution should work for me anyways? If so, there is one think I did not understand: 1. I replaced the gps.ino 2. I added the code into the config.h 3. I set the GPS to 57600 baud 4. Where exactly should ...

Re: GPS integration

Correct. The above code works with the default 9600 baud rate. On each initialization, it changes the GPS speed from 9600 baud to 57600 baud (and the update rate to 5 hertz).

Re: GPS integration

The RcTimer u-blox GPS that you bought defaults to 9600 baud. the GPS config options need to be set to 9600. I use the updated GPS code that EOSBandi wrote for 2.1 (Found on this forum). That code will connect at 9600 but then change the baud rate to 57600 with a 5Hz update. Also make sure you're wi...
