Re: Pointers for multiple CFs with the Loco?

Thanks, that's very helpful. So, based on https://forum.bitcraze.io/viewtopic.php?f=16&t=2527, the update rate for a full set of ranges is: 1 / (0.004 * 2 ^ TDMA_NSLOTS_BITS * N_ANCHORS). At what point do you think that rate gets slow enough that the Kalman filter has a hard time getting a good ...

Re: cfloader reset to bootloader not working

Thanks, knowing that it's likely the Python library is a good start, and I'll check out crazyserver regardless.

Not on the top of my TODOs, but I'll update this thread later if I get it working.

Pointers for multiple CFs with the Loco?

Hi, I'm starting to work on getting multiple Crazyflies in the air together using the Loco anchors. In general, I'm looking for any wisdom from people who've tried the same. I understand I have 2 options: TWR-TDMA and TDoA. Which would you recommend exploring first? Is TWR-TDMA more supported / stab...

cfloader reset to bootloader not working

Hi, I haven't been able to get "reset to bootloader" option to work with `cfloader` as suggested in https://github.com/bitcraze/crazyflie-firmware/blob/master/tools/make/config.mk.example#L24 It seems to be hanging up here https://github.com/bitcraze/crazyflie-lib-python/blob/master/cflib/...

Re: Crazyradio PA death (D1)

Perfect, that answers all my questions. Thanks!

I'll look into printing something like https://www.youmagine.com/designs/crazyradio-housing or http://www.thingiverse.com/thing:130857 to protect against possible shorts from handling.

Re: Crazyradio PA death (D1)

Also I guess:

4) Do you have the manufacturer + part number or specs for D1?
I imagine most anything slightly over-specced will do, but I'd like to just get some next time I'm on Digi-Key.

[SOLVED] Crazyradio PA death (D1)

Hi all, I've solved my own problem for the time being, but I wanted to post here in case anyone else found themselves in similar trouble, and with a couple of follow-up questions. First off, thanks so much for publishing the schematics! This would have been *much* harder to diagnose without them. Op...

Re: about deck board , how to write id into eeprom DS28E05 ?

Arnaud, Thanks, that's perfect! The risk I was talking about was flashing a special firmware onto the Crazyflie that forced an EEPROM program on boot, and forgetting that I had that firmware flashed and overwriting something. Being able to trigger it from the host side is much better. I take it that...

Re: about deck board , how to write id into eeprom DS28E05 ?

(bump) I'd like to write to identify my experimental decks automatically, too. Does anyone happen to have any utilities for writing to the DS28E05? The main problem I'm having is that the DS28E05 only supports overdrive mode. I tried talking to it using the BusPirate, but the BusPirate doesn't suppo...
