Hi! I am trying to use CMSIS DSP transform functions inside a task I created for the Crazyflie but I am getting an "undefined reference error" (see below) which I find strange because I can successfully use other DSP functions like "arm_sqrt_f32" which I tried as a test. I have a...

Ok thanks for the advice, if I succeed I will post the solution here.

Hi! I would like to sample data from the ADC at a frequency of ~2kHz and process it internally before logging the result at the regular 10-100Hz with the python client. I am having a hard time accommodating this functionality in the firmware with an APP or a deck driver and for this reason I would l...

3 years later... but in case it helps someone I made a very simple program that uses the APP Layer https://www.bitcraze.io/documentation/repository/crazyflie-firmware/master/userguides/app_layer/ to send an analog value to the client's console: #include <string.h> #include <stdint.h> #include <stdbo...

The problem seems now to be solved by logging at 10Hz and also increasing the amount of resources allocated to the VM.

Also, important to set the USB controller in VirtualBox to USB2 and connect your CrazyRadio to a USB2 port.

Thanks for the help!

Ok thanks for the clarification!

Oh in that case I think the following test of basiclog.py will bring clarity to what's happening: - I run the program and the Crazyradio's red LED is blinking for ~1:20min (more less consistently in multiple tests) while the console prints: Scanning interfaces for Crazyflies... - After this time, on...

Hi! I want to use the Lighthouse deck to take advantage of the photodiodes (PDs) onthe board to do visible light positioning without the need of creating a new custom board. I see that the PDs have a good enough sensitivity response in the visible light spectrum and I want to log the received signal...

Thank you for the reply. I changed the crazy radio from a USB3 to a USB2 hub and I see that in all cases the red LED on the Crazyflie is flashing a lot... Even when the Crazyflie is close to the antenna and I tried in different rooms to check it was not external interference of some sort. In contras...

Hi I have been using the Crazyflie for around a month and recently I noticed that when attaching the multiranger deck the Crazyflie's self test fails, but when I remove the deck then it passes. I would order a new deck but the problem is that now my Crazyflie is doing some weird things: 1- When usin...
