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 ...

Re: Autonomous flight using wall following

Hi, Can you explain a bit more what work and what does not? Intuitively, your algorithm will make the Crazyflie collide with the wall since the Crazyflie is never able to get away from the wall, only closer. ps: Can you please use "code display" in the menu when writing your message for block of cod...

Re: Logging more than 6 Parameters at once

Sure! One added note: you can setup more than one log block, so the normal way to log more than 6 floats is to setup multiple log blocks. However, being able to log as much as possible in a single block is more efficient and can be more practical, so its nice FP16 finaly works all the way.

Re: Setting parameters when autonomous / set kalman state

I do not think this function was meant to be blocking. What is happening is that when you set a parameter from inside the Crazyflie, it sends a packet to the client with the new value. If no client is connected, the packet TX queues become full and so the function blocks until it can put its packet ...

Re: Logging more than 6 Parameters at once

This is a limitation of the log subsytem: one log block must be contained in one radio packet and the radio packets are 32bytes long, when removing timestamp and other required data there is about 27bytes available, so 6 float plus a 3 bytes. That said, the Crazyflie has a functionality to convert v...

Re: No pysdl2 installation found

Hi, If you want to develop for the Crazyflie, it is usually easier to use Linux since all the build environment work on it without trouble (and most of us at Bitcrare are on Linux). It would be better to be on Ubuntu 20.04, things like gcc-arm-none-eabi are now in the Usbuntu repos and do not requir...

Re: Updating firmeware getting stuck when updating lighthouse deck

Hi Timo, It is possible you are hitting a but I am currently fixing, the fix is in the client git and a new release of the client will be published today. The problem is causing the flashing process to hang in some condition (we have observed it when the flow deck is attached but it is an unitialize...

Re: Connection problems with radio and delay

Hi, I can reproduce what you are seeing with basiclog.py on Windows in using the VM. I am not so sure where it come from yet but I am investigating. One workarround is to log more slowly: when logging at 10Hz I do not see the delay anymore. Another workaround is to run natively: installing the lates...

Re: Hover mode on Android client

This is a pretty old problem. TLDR: I do not think this statement is still fully accurate and starting a ticket on the android client github project would be the best way forward. Now for the long story: When this was written, the only assisted mode available was altitude-hold with the pressure sens...
