Re: Optimum Flow Deck Surface

I kid you not, this is by far THE best solution out there!
We have about 20 of these that we lay out on the floor before we fly.

Re: Flow Deck Data Collection

Hey guys,
Is it possible to wirelessly transmit the fused odometry update from the EKF while flying with the flow sensor?

Thanks!

Re: make[1]: *** [cf2.elf] Error 1

This is due to an incompatibility issue in the arm toolchain and Ubuntu 18.04. If you've installed the arm toolchain using an apt-get ppa, you have an older version that causes this issue. run arm-none-eabi-gcc --version to find what version you have installed. I've found that upgrading to Version 7...

Crazyflie2 charge current

Hello all, Is it possible to increase the charge current of the CF2 from 400mA? The BQ24075 seems to support up to 1.5A, and new batteries can be charged at 2C, is there a way to bump it to ~800mA? Seems like enabling this should work - correct? https://github.com/bitcraze/crazyflie2-nrf-firmware/bl...

Re: Flow and LED deck combined?

Nevermind.... I just saw that IO_2 is NOT used on the flow deck :P

Even though the schematic shows R4, R5 and R6 connected to IO_2, they are not populated on the boards.
Maybe update the schematic to reflect this?

Re: Flow and LED deck combined?

Huh... then how does the firmware handle it?
When the drivers for the flow deck and ring deck are enabled, IO_2 is still overloaded in the firmware right?
That is, the ring deck will output a PWM on the line, and the flow deck driver will implement the RESET/MOTION logic?

Re: Flow and LED deck combined?

Hmm, that's very interesting! Great article! Operationally, I have a question - the Flow deck uses the LeftExpansion7 (IO_2) pin and so does the LED Deck for the serial data for the WS2812B LEDs (labelled on the schematic as PWM_DOWN). How does that pin overloading work? Images for reference... Flow...

Re: CF2.0 Hardware upgrade

Hi @arnaud, The redesign I spoke about a few months ago turned out to be successful and we have 25 working robots! Though these are binary compatible with the existing CF2, I am hoping to speak with you guys on how we can make it available to the community. I hope a lot of people will find the redes...

Re: Consistent attitude offset in CF2.0

Yes, and as I mentioned in my original post, I rewrote the default eeprom settings using the write-eeprom.py script.

In any case, here's the config window:
