Re: Replace motors with brushed

Yeah, I mean CW and CCW. The CCW motors need to have their leads swapped in the connector to spin in the correct direction on crazyflie.

Re: Crazyflie 2.0 - Power Button Fell Off - Two Blue Lights Stuck on (M3 and M2)

Hey Tobias -- hopefully this isn't a red herring, but this sounds similar to the board I sent you a while back. The power button got ripped off in a crash and then I wasn't able to communicate with the STM or boot it into recovery (by shorting BOOT0) any more..

Re: Replace motors with brushed

I have upgraded my FPV crazyflie with those exact motors. Some notes: - The motors are very slightly larger in diameter. They do fit in the plastic mounts, but they put extra strain on the plastic. Expect to break many more motor mounts. I typically break one very time I crash. - As Tobias pointed o...

Anchor count for TDoA v2/v3

Hi -- it's unclear to me from the docs on the wiki whether 8 anchors are strictly required for TDoA 2/3 to work, or whether they just work better with 8 anchors. I've only got six anchors - am I limited to TWR or should I expect TDoA 2/3 to work too?

Thanks!

Re: Betaflight support for CF2.0

No, that's correct. You should have a 9250. The 9250 is actually the 6500 plus a mag so betaflight treats it as a 6500.

I'll stare at the code a bit more.

A video of the lights (error code) would be helpful too if possible.

Re: Betaflight support for CF2.0

Hey thanks for the details. Sorry for the delay; busy week. Unfortunately, this doesn't repro for me, using your workflow (and 10.1.0). The four-blinks after boot is an error code, which indicates "FAILURE_ACCEL_INCOMPATIBLE". According to the code, this error triggers based on a revision check for ...

Re: Betaflight support for CF2.0

Which version of the betaflight firmware? (10.1.0 is the configurator, right?)

I haven't seen this error but I haven't tried moving past Betaflight 3.2 just yet. I'll grab 10.1.0 and try it out later today.

Re: Betaflight support for CF2.0

Hey forum Another update - Betaflight 3.2 was officially released this month. This is the first release that contains the Crazyflie 2.0 target by default, so you don't need to clone and build from source anymore. It's available as a target in the betaflight configurator from the google chrome store!...

Re: Tuning crazyflie for smooth, stable and responsive flight

I mean rapid increases to max throttle. The behavior happens most commonly when you go immediately to 100% throttle at takeoff. I can also see it when you go from hover throttle to 100% immediately during flight. The behavior is hard to describe, but it looks like an uncontrolled oscillation or dest...

Re: Tuning crazyflie for smooth, stable and responsive flight

Hey all, it's been a while. Here's some updates for those who are curious: I've made some changes to how UART is handled that lets us reduce the syslink task priorty. However, I also determined that the massive 20ms+ spikes only happen when connected through USB instead of OTA, so it's less of a con...
