Re: question about log period_in_ms and commander.send_setpoint function

this is good information to have in the documentation. maximum recommended bytes or blocks per second. Also on USB (I assume it is higher)

Re: Access to tick from another source file.

first, you are using PARAM_ADD where LOG_ADD should be
second, you can use log variables to internally transfer data between tasks, also RTOS queues are used
I didn't use pointers so will be also interested to hear if this is supposed to work

Re: FPV Flight Hardware

I used very similar hardware successfully. make sure you put the camera where it won't imbalance the drone too much.
yes you need the video receiver and it can work independently from the crazyradio without issues.

Re: flipping the motor direction in the firmware.

I think you need to flip something in the IMU too

Re: Custom sensor connection

did you compile the firmware using DDECK_FORCE flag to force it to compile your virtual deck? see the tutorials if not.
also, I recommend posting the output from the console (self test results)

Re: good propeller test values

unrelated to lighthouse issues, I also found that in some crazyflies the motor PWM values differ consistently while hovering. In many cases two motors will have higher values and the other two will have lower values. you can use motors.m1 .. motors.m4 log variables to test this while hovering. Repla...

Re: Recommendations with Flow deck

if you have access to a print shop, it might be simpler/cheaper to print something like this . works well in the correct scale. use high contrast.

Re: downloading a log file from the SD

update 2: it works! the only thing is that the rate is ~1.5KB/sec (both radio and USB). in the CPP implementation by whoenig it was ~3 times faster.
anyway I am considering making some improvements for performance, any suggestions welcome.
the modified code is posted as a PR in the cflib github

Re: downloading a log file from the SD

just a quick update, after some tests with crazyflie_tools, downloading using radio or USB does not matter much in terms of speed, on USB I get 4-9KBps and on radio around 7KBps. I started writing the python functions to allow downloading and will update again.

Re: downloading a log file from the SD

Thanks for wyour reply whoenig! I wrote the post and found out about your answer only later.. :oops: I have a few specific questions after studying your answer- first - I understand the usddeckRead method used in the firmware is relevant only for an active logging session which was stopped but the d...
