"The DCM algorithm is basically the same. The difference is just in using libraries for the gps and magnetometers.
We are migrating lots of pieces of code into libraries so that they are easier to maintain across all of the "products"."

Question about integrating ArduIMU with Paparazzi

I am in a group working on Paparazzi. For my 48" Delta wing airframes, I have been using the thermopiles for a while which actually prevent me from getting my project going. So I turned to low cost…Continue

Dee L. Di replied to Dee L. Di's discussion Question about integrating ArduIMU with Paparazzi"Thanks, Doug, you have answered my questions. But I am still curious about how different is the new DCM code (1.8.1) compared with the version ArduIMUV2_DCM_V10, because from my flight test, it didn't improve much, maybe it is still because the…"

"Hi Dee,
Have I answered your questions by PM, or do you still have questions?"
Dee L. Di replied to Dee L. Di's discussion Question about integrating ArduIMU with Paparazzi"Thanks, Chris. Yes the first question is uBlox ground speed, heading, down velocity can not be updated at 4Hz while the longitude, latitude, etc can. The timing for version 1.8.1 is also strange because it decodes the GPS at 8Hz but send them at…"
ModeratorChris Anderson replied to Dee L. Di's discussion Question about integrating ArduIMU with Paparazzi
"So just to be clear, your two questions are:
1) Why is the uBlox ground speed not updated at 4Hz?
2) When you fiddle with the ArduIMU DCM code, the timing gets messed up. Would that be better in 1.8.x?
I can't answer either of them, but…"

I am in a group working on Paparazzi. For my 48" Delta wing airframes, I have been using the thermopiles for a while which actually prevent me from getting my project going. So I turned to low cost IMU and Ardu is the very first choice. So far I have made the Ardu+Ublox configuration work with Paparazzi autopilot and it looks great on the ground, and I have done several flight tests. But when I flew it,the IMU data got distorted, basically in Paparazzi Auto1 mode (which means the UAV is…See More
