Re: Kalman-Filter, Update position from source other than LOCO-positioning

Hi Arnaud, I actually forgot to buy bigquad deck.. so I quickly added some pullups to the Crazyflie brushed driver outputs and made some quick change to motor mappings - did work just fine :) I'll let you know once I got it running on out of the box Crazyflie. Just need to order more Crazyflies in o...

Re: Kalman-Filter, Update position from source other than LOCO-positioning

Hi Arnaud, it is a prototype of an ASIC (Image-Sensor) + microcontroller circuitry that has been designed to do optical-flow and obstacle avoidance. I need to check if I'm allowed to tell more - I'm lucky to actually have the chance to play with one of the prototypes. Yes, you are correct. I'd like ...

Kalman-Filter, Update position from source other than LOCO-positioning

Hello everyone, Hi Arnaud! As already started in comment to "Loco positioning system" Blog post, I'm doing (or want to do) position control with an "arbitrary" source of position estimation. In my case I'm using a prototype of an optical flow odometer (4 stereo sensors), which is...

Re: Issue using <stdlib.h> in CrazyFlie Custom-Deck Driver

Hi Arnaud,

yes off course strtol()... shame on me. Now it's working as supposed. Sorry for that!

Thanks for trying/checking!

Issue using <stdlib.h> in CrazyFlie Custom-Deck Driver

Hi, I'm currently writing a custom deck-driver to implement some rudimentary collision-avoidance on CrazyFlie using SiliconRadar's Radar-Sensor PCB v2. I have already written another deck driver before to drive a prototype of a motion-flow sensor for indoor position hold. I found it very simple to g...
