"@Jake Stew, I really liked your comments and appreciate here about the DMP feature of Invensense sensor chips. They can't ask the user to not to use the specific feature of any chip which they have advertised & made money. I also…"

"You can't open source binaries period.  There is no source, it doesn't exist on the public internet. If you need a binary blob to make full use of a product they're never going to be able to sue you for including it in your…"

"You can't open source some hacked binaries found on the web. You can use them for private experiments for sure, but not projects released as public open-source. For it to be legally sound, the hack would have to be a documented clean room…"

"Hi everybody. I really don't mean to be rude but: We have all bought the hardware and should really just start using it. How about we stop whining about Invensense and start getting a working library going for the ArduIMU3. There is partly…"

"True that it has taken time to get information as InvenSense has proved that it will not deviate from their policy on this matter. They do however put their product out their with good intentions and confidence. Like any well intentioned business…"

"There is no "IP standpoint".  If they had anything innovative it would be covered by one or more of the dozens of patents on this thing.  Disclosing the interface has nothing to do with IP, it's just the difference…"

"Open source purity aside, most of my resentment has been based on the fact it has taken over a year for a detailed explanation of these details to become public knowledge. It was pulling teeth to get the information at all and has trickled out only…"

John Arne Birkeland replied to Frank Zhao's discussion ArduIMU V3, source code for DMP?
"The problem is that open-source could not care less about any IP 'advantages' and black-box technology is a big no-no. By now DMP is pretty much considered vaporware in much of the the open-source/hardware community. All the good will from…"

dronecrazy replied to Frank Zhao's discussion ArduIMU V3, source code for DMP?
"The initial position comes from an IP standpoint. The DMP and it's function are considered to be a key competetive advantage and thus must be protected, especially the mystery binary. In regards to it not being promgramable that has to do with…"

Jake Stew replied to Frank Zhao's discussion ArduIMU V3, source code for DMP?
"I glad it actually exists.  I just don't understand why a company would act so shady about their product unless they were hiding something though. I mean it's taken a year just to get a peek at doing anything with it.  All the…"

"Hey Jake, The DMP does exist, I'm glad you were able clear that up. To put it simply the DMP is a math engine, or hardware acclerator that processes 6-axis sensor fusion algorithms and some calibration algorithms. It is by no means your…"

Jake Stew replied to Frank Zhao's discussion ArduIMU V3, source code for DMP?
"I think you've uncovered the first real bit of evidence that an actual DMP might exist! So now it has become clear why Invense has finally opened things up... Not because they wanted to, but because some hackers have finally reverse engineered…"

"I'n not working on the DCM so this might be wrong. But from my understanding the reason the library looks a bit weird, is because we are fusing internal MPU60x0 sensors (gyro + accelerometer) with external magnetometers and GPS. So first you…"
