Re: Logging time onto sd card

I do not think the exFAT file-system is handled by the Crayflie. The SD-card needs to be formatted using the Fat(32) file-system.

Re: Send pitch angle

Without the exact code, it is hard to know what is happening. I tried your experiment by holding the Crazyflie between my fingers keeping the pitch axis free-ish and the following code worked for me: it kept pitch at ~10degree for 2 seconds and at ~0 degrees for 2 seconds before stopping: # -*- codi...

Re: initial state

It is now in the git repos so it is available if you compile and flash the firmware from source. It will be part of the next release but we do not know when that will be yet. You can also set the initial ekf position with the parameters and reset the EKF using parameter as well to get the current ve...

Re: Z_distance commander coordinates logic

This is legacy and unfortunately I do not have an answer for that other than this was required to get the yaw to work in the right direction. Since we are keeping the radio packets backwards compatible, this is not something that can be changed without breaking backwards compatibility. Another oddit...

Re: lighthousev2 get_bs_geometry is not working well

Can you explain in more details what works and what does not? Are you seeing the symptom I described in this other post for one of the deck? viewtopic.php?p=21928#p21928

Re: Updating firmeware getting stuck when updating lighthouse deck

Hi, You might be hitting a bug that I tried to fix during the 2021.03 firmware development. The symptom was as follow: - When starting the Crazyflie using the power button, the lighthouse deck starts (the blue LED lit up) - When the Crazyflie restarts from bootloader to firmware more, ie. when it re...

Re: 2 Crazyradio

Hi, The first number of the URI indicates what radio is being used. So, assuming your two Crazyflies are on channel 60 and 80 with different addresses you will be able to connect "radio://0/60/2M/E7E7E7E701" and "radio://1/80/2M/E7E7E7E702" to connect the two Crazyflie using the two radios. A couple...

Re: Assert failed at radiolink.c:164

FreeRTOS does handle tasks based on priority, but the estimator is set as pretty high priority since it is the most important code in a flying platform, so it can starve the rest of the system. I am not sure this is what is happening there however, you should be hitting the watchdog in that case: th...

Re: STM32 driver install

A quick search shows that the cause is likely with your installation of Windows being damaged: https://github.com/pbatard/libwdi/issue ... -735964681. Can you try on another computer or another install (for example in a VM) to see if it fixes the problem.

Re: Trigger a signal to take range measurement each time pic is taken

Hi, I have not used much (ie. at all) the AI deck but I know pretty well the Crazyflie so I can try to help with some pointers. There is a UART connection between the Crazyflie and the GAP8 but unfortunatly in version 1.0 of the deck, only the way from the GAP8 to the Crazyflie work. On version 1.1 ...
