Re: GPS integration

Hello Tazzy, I am using the GPS from RCTimer (CRIUS), I have no way to confirm what the GPS Speed is as they come from the factory. It is plug directly to the I2C board, also from RCTimer (CRIUS). The cable between the two boards is pre-made and matches the picture shown at their site. Currently, i...

Re: GPS integration

Can you post your code for the configuration sequence? I too have problems with the RCTimer GPS loosing the settings. Thanks! Insert this just after "void setup() {" in your I2C_GPS_NAV.ino (version r33!!!!). I know that code isn't pretty and should be optimized, but there was lot of free...

Re: GPS integration

I guess that nobody is flying indoor or in so dense forrest that needs one more dB gain of GPS antenna. Present GPS modules are sensitive enough that difference in ones dB between various patch antennas does not matter. I prefer lighter module, every gram counts... Crius GPS module from rctimer.com...

Re: GPS integration

Great work EOSBandi! I have a Ublox Neo-6M and used your ublox config file. Also running the new I2C code with binary Ublox mode. The config file is set to a 10 hz update rate which the 6M accepted but it is really only a max 5 hz chip. At 10 hz seemed to drift around more than with old I2Ccode and ...

Re: GPS integration

For a U-blox NEO-6M RCTimer GPS Module with a RCTimer I2C interface board: Is there a way to have the I2C code update the Baudrate to 115200 and Update rate to 5hz when you initialize the board? Config set in u-center only get saved for a couple days then defaults back to 9600 baud and 1hz update ra...

Re: Crius SE GPS & Latest DEV

I've got one hooked up thru the 328 board, how much variation did you have and how much do you have now? Mine holds stable within a 2m box with near zero wind. Can you post your PIDs?

Re: GPS integration

One more issue : I found that the onboard battery of these ebay ublox modules are hardly last more than a couple of days... and since the neo-6M does not have flash onboard, then it forgets the settings. I've read that you have to charge the onboard battery for about 24 hours. I did so by applying ...

Re: GPS on Crius SE board

Ok, I got the RCTimer GPS & I2C board working with the smaller Crius V1.0 board. I used U-Center to config the baudrate to 115,200 and the sampling rate to 5hz. Seemed hard to get the config setting changes to stick. I could never get the protocal to stay on only "NMEA", it would alway...

Re: GPS on Crius SE board

I just got in the RCtimer setup today and have been trying it out tonight. Also got the Crius V1.0 FC board. I flashed the board to dev 6-22. Commented out GPS baudrate line, and uncommented IC2 line and all the other normal non-gps stuff. Only watching it across the FTDI now, not connected to my qu...

Re: Throttle is slow after switching from 1.9 to 2.0 on Criu

I think I figured it out. I just implemented the Low Pass Filter in the Config.h file. Started at 42Hz, still acting bad, lowered it to 20Hz, all good. Guess I just have too much vibration in my setup. I balanced the props on a magnetic balancer, maybe there're too flimsy, GWS 9050 tri-blades. GLB p...

Throttle is slow after switching from 1.9 to 2.0 on Crius SE

Been running factory 1.9 MultiWii code on a GLB Cruis SE board on a quad. RCTimer 28-30/14 motors, Turnigy Plush 25 escs. Run 3s and 4s 2200 packs. All runs good on the 1.9 code. Baro doesn't work good. Flashed to 2.0 and now throttle hiccps on 3s and is slow to respond but still works fine on 4s. W...
