Re: Does the flow deck work on a Big Quad?

I checked out be53c5ad4d61bf03752cce997037fb8807f8f349 from 4th of October 2017, also not working.

Re: Does the flow deck work on a Big Quad?

By the way, all of our Flow Decks seem to be Rev D, the schematics on the wiki references Rev E, though. Is that of any importance?

Re: Does the flow deck work on a Big Quad?

We do not have anything connected to the Big Quad Deck except for the motors, BQ_DECK_ENABLE_PM is not defined, I checked via printout to the console, nor is BQ_DECK_ENABLE_OSD. I posted some pictures of the experimental setup here (more info in the captions): https://imgur.com/a/Ln0Y0Go I disconnec...

Re: Does the flow deck work on a Big Quad?

It looks like reading data from the flow deck over SPI fails, when a Big Quad Deck is connected.

You said it worked for you at some point of time, do you know which changes could have broken the functionality?

Re: Does the flow deck work on a Big Quad?

We made the proposed changes (unsoldering C1 on BigQuad Deck and IO1 of the CF is connected to IO3 on the Flow Deck - Firmware changes see below) and the flowdeck seems to be recognised. --- SYS: Crazyflie 2.0 is up and running! SYS: Build 153:5b00ad02c63c (2018.01.1-153) MODIFIED SYS: I am 0x303436...

Re: Does the flow deck work on a Big Quad?

Thank you for your answer. We did try reading the sensor values and in combination with the big quad deck they are garbage, once we remove the big quad deck, everything works fine. From a close look to the console, we can see that the deck is recognized, but the sensor is not initialized correctly. ...

Does the flow deck work on a Big Quad?

We mounted a flow deck on a Big Quad (with 2 breakout decks and some cable), sensor readings appear to be fine, still hover mode leads to building up oversteering until there is a crash after a few seconds. Did anyone successfully try this combination? Is it supposed to work or is it expected, that ...

Re: Logging the Data When the CrazyFlie is Flying Autonomously

If you are already able to log roll pitch and yaw, then you just need the names of the respective logging variables. The relevant logging variables for position are: - kalman.stateX - kalman.stateY - kalman.stateZ as far as I know. More information is here: https://wiki.bitcraze.io/projects:crazyfli...

Re: SD Card Deck and Flow Deck not working together

Is there a previous firmware version where the SD-Card and Flow deck worked together?

Re: SD Card Deck and Flow Deck not working together

Is this a problem, that is only known in some settings (some SD cards etc) or can you not log either? We want to log that frequently, because we want to rebuild the results achieved in this paper using the flow deck for (approximate) localisation instead of a vicon camera system: https://arxiv.org/p...
