Compass "Live Calibration" - not seeing axes rotating, white dots, or data points

Started this discussion. Last reply by Nick McCarthy Jun 2, 2015. 6 Replies

I've had both successful and unsuccessful attempts at Live Calibration with the Pixhawk and Pixhawk clones using USB and Telemetry.Currently, I'm trying to setup a new airframe, and am not seeing any…Continue

"Has it been integrated with the APM platform to enable precision landing ?"

"I think it offends most of our sensibilities calling this the "The World’s First Customizable, 3D-printed drone". Most of us have been doing just that for years."

"Very cool! I'm also thinking about making one for novelty, perhaps with a FX-79 or smaller FX-61"

Nick McCarthy replied to Euan Ramsay's discussion Particle electron instead of telemetry radio in the group Telemetry over cellular IP
"I also just received a Particle Electron and am considering how it can be integrated with a drone. I'm not sure what kind of bitrates we can expect with 3G data, and it may not be cost effective to use Particle's MNVO for large amounts of…"

Nick McCarthy commented on Chris Anderson's blog post Solar-powered launch system allows totally unattended operation
"I think a lot of what H3 Dynamics is selling in this video is hype. There appears to be no demonstration of moving energy from fuel cells or solar panels into the drone, and their Iris seems to be unmodified (except for the IR-Lock beacon). Still, I…"

Nick McCarthy replied to Felix Meissner's discussion LidarLite working correctly? - SOLVED
"Best I know, they unfortunately stopped production. It's not clear if Lidar Lite as a product will fit into Garmin's line-up, or if the technology will be integrated into other devices."

Nick McCarthy replied to Felix Meissner's discussion LidarLite working correctly? - SOLVED
"And just like that, I'm having the problem again. This time on the new copter using PWM (where data initially looked good on first boot). Pretty dumb-founded on this one. I also switched to APM:Plane, where I'm seeing the same issue."

Nick McCarthy replied to Felix Meissner's discussion LidarLite working correctly? - SOLVED
"Problem Solved: After considering the strange Lidar readings I was getting, even in PWM where sonnarrange did not match sonarvoltage were not from the following: Bad Lidar-Lite (Works fine on other copter) Bad Params (reset to defaults) Bad…"

Nick McCarthy replied to Felix Meissner's discussion LidarLite working correctly? - SOLVED
"Felix, good idea - The 5V supply is looking clean, coming from a BEC. I think I just discovered the fix, posting above."

Nick McCarthy replied to Felix Meissner's discussion LidarLite working correctly? - SOLVED
"So I've connected this Lidar to another copter I have, currently running 3.4-dev. Using PWM, I see sonarvoltage and sonarrange both correlate well to actual distances. So it seems the problem resides with my original Pixhawk, on a 3DR Iris+. I…"

Nick McCarthy replied to Felix Meissner's discussion LidarLite working correctly? - SOLVED
"Thanks for the details Stephan,  I've just rewired my Lidar Lite to connect via PWM. Here's where things get baffling: sonarvoltage reads what appears to be proper voltage levels to distance: IE: 0.80 v for 80cm. This looks great -…"

Nick McCarthy replied to Felix Meissner's discussion LidarLite working correctly? - SOLVED
"@ Felix and others: I'm using a Lidar-Lite v2 connected via I2C, and I'm trying to make sense of the readings. It seems to me that there is a scaling being applied. I'm seeing similar readings in Copter 3.3 as well as 3.4-dev Ruler…"
