Broadcasting with Crazyflie

Hello everyone, we are currently trying to implement a Broadcasting function within the Crazyflie 2.0 / the nrf51822. What we are looking for is a discussion/similarities/differences between the p2p API of bitcraze and our approach - maybe avoiding some issues/problems we are not seeing yet. In addi...

Re: stlink v2 Debugger not working in current firmware

Hello Tobias,

this definitely solved my problem, it even works out for my branch containing my modifications so I can proceed working on my algorithm

Thank you very much

Re: Free RAM for additional code mofications

Good Morning! Thank you very much. We'll make use of your tipps - there is an additional requirement to store path data from at least one other Crazyflie in addition to the own path for the algorithm we plan to implement soon. Storing positions of other Crazyflies -> definitely yes, this would be ve...

Free RAM for additional code mofications

Hello, integrating some additonal code initially developed on top of the firmware from early 2019 (and worked fine there), I integrated this code into the most recent firmware version. Doing so, compiling (cload) was not successful, causing the error ".bss" will not fit in region 'RAM'. Reducing mem...

Re: stlink v2 Debugger not working in current firmware

Hello Kimberly, yeah sorry, in fact it was a tough fight on my side with some up and downs concerning the debugger and some stuff has become mixed up: In fact we are working as a group and all members using stlink-v2 debuggers and had no trouble working with the firmware from early 2019 as basis. Ho...

Re: uart_syslink assert

Hello, I just want to refer to my second post concerning firmware crashes when debugging. I supposed the problems would be decoupled but it seems the uart issues using Flow Deck v2 and LPS deck simultaneously seem to be even more critical in the new firmware - at least for Crazyflie 2.0 and using th...

Re: stlink v2 Debugger not working in current firmware

Hello, a short update: I just received a message of my students: He experienced the same behavior: the unmodified bitcraze-firmware crashes when debugging with Flow Deck v2 and LPS Deck attached to the Crazyflie 2.0. I have to stress: He is set up his toolchain under windows (cygwin) completely inde...

Re: stlink v2 Debugger not working in current firmware

Hello again, I could not leave this problem aside. For some reason, after lunch the debugger could be launched again (Maybe, I just should have tried a reboot although I thought that I did this....puh ) and stops in main as desired. However, any Crazyflie (2.0 and 2.1) which is equipped with a Flow ...

Re: Commands from Simulink to Crazyflie

I really understand the wish to be able to develop with Matlab. As control people, we are quite used to develop our stuff with this tool and in an university environment, we usually have some sort of 100% access. Using the python API to run a low level (stabilizing) controller on a pc which processe...

stlink v2 Debugger not working in current firmware

Hello again, due to some suboptimal git configurations our git repository was decoupled from the bitcraze repository since last summer. This actually seemed to cause my uart-related problems discussed in another post. Today I went for a "fresh start", so taking the current firmware and creating a ne...
