Hi Esteban, Really cool project! First thing you need to know about the Flowdeck and the optical flow sensor it uses, it is indeed not as perfect as it would be using a MoCap or the lighthouse positioning system. The PMW optical sensor is optical based and therefore has its limitations, so it would ...

Hi Na, THat sounds like an awesome platform :D. It seems like you were on the right path with changing the power distribution (power_distribution_stock.c), that could be the easiest solution. The next step could be to define your own motor mapping, but to be honest I don't have that much experience ...

Just to give an conclusion to this forum thread (sorry for the late update). I got a replacement of the flowdeck v2.0 and they were all working fine. It was indeed the connector, and the errors I noticed was just because it was not connecting properly

I was able to sort of trace the problem down to the I2C communication. Unfortunately my gdb debugging on the stm doesn't work so I can't really efficiently debug it any further. However, the following line is quite interesting: EEPROM: I2C connection [FAIL]. If I remove the flowdeckv2, or replace it...

Hi all, I just purchased the new flowdeckv2, however my crazyflie2 has trouble reading it out. It recognize the deck but I get the following readout in the console, along with the 3 times fast blink of M1: SYS: ---------------------------- SYS: Crazyflie 2.0 is up and running! SYS: Build 187:47ee696...

I was able to fix my above mentioned problem by adding the following to the config options of the OpenOCD setup :

-c "stm32f4x.cpu configure -rtos auto"

Nice job:) Were you also able to debug the crazyflie2 firmware with the RTOSfree threads with breakpoints and such? I'm having problems with that myself.

Hi all, I am currently working on my own expansion deck, where I would like to use both UART1 and UART2 on the CrazyFlie 2.0. I noticed in the code in the current master, that the driver for UART1 (uart1.c) contains functions for both TX and RX ( uart1GetDataWithTimout(), uart1SendData(), uart1Putch...

Thanks theseankelly and Tobias for your quick replies! I'm glad to hear that you already tried them before on the CrazyFlie so at least I know it is possible. I do have some improved batteries I used for the drone I was flying with previously (Lisa-XS with Walkera Ladybird frame), which I got from h...

I would like to replace the current coreless motors of the CrazyFlie 2.0 with more powerful brushed motors, similar to these: https://www.amazon.com/gp/product/B01M12WJ7N/ref=oh_aui_search_detailpage?ie=UTF8&psc=1 In the crazyflie firmware repository, it seems that there is already support for b...
