Hello everyone, this is Victor and I’ve spent another internship here at Bitcraze. You can read my blogpost from last year here I have learned a lot since last year so it has been fun to put my skills to test!

This summer I have spent my time on improving the cf-client. I’ve fixed a few bugs but mostly it has been about making small changes that improves overall functionality.

Some of the improvements that I’ve worked on:

  • Flight-control tab: Added logging of x and y-axis and changed the columns to more suitable groups. Also improved UI for assist mode.
  • Flashing dialog: Added support to flash both of the MCUs individually as well as choosing which one to flash (previously you could only flash the stm32 or both). Created an automatic firmware-release-downloader, so that you don’t have to download the files manually.
  • Log-config: Added grouping of log-configurations, that allows you to group the configs into categories. Also added small functionalities like double-click to add, remove configs etc.
  • Added sort-support for all list/tables.
  • Removed traces from Crazyflie 1.0 and support for x-mode, since it is no longer supported by the client.
  • Removed traces from python 2.

I hope that the functionalities will help you and make your experience with the client better. If you have any tips for further improvements, you’re more than welcome to leave a comment or contribute yourself. This is my last week for this summer, but I hope to see you all again and until then, fly safe!

Hello everyone, I’m Victor and you probably haven’t heard of me yet but I’ve got the awesome opportunity to spend some weeks during this summer working at Bitcraze. Working… Well, I’ve spent the majority of my time here getting invaluable experience, programming, flying with drones, eating incredible falafel and having fun so it’s really been a pleasure.

I’m quite new to both programming and electronics, so while I haven’t created any huge masterpieces of code yet, I did make a small program with a GUI that let you test the health of motors and propellers of the Crazyflie. You can run multiple ones simultaneously (I’ve tried up to 8, which works fine, even with a single radio, and you should be able to run many more) and it relies on using either Lighthouse or a Flow deck for positioning.
The propeller-test is essentially the same test as the one integrated with the cfclient, however the motor-test checks the thrust-levels of the motors (by hovering in the air for x seconds) to see if any of them are off and ranks them as good/bad. The default threshold is 15% but can be changed according to needs. The program is written in Python and uses tkinter to run the GUI application and the cflib to communicate with the Crazyflie. The script can be found here.

In the end of August I’m going to study Computer Science and Engineering which I’m extremely thrilled about and this has really been a perfect preparation for that! In the future I hope to contribute to the Crazyflie projects and learn more from the great team here at Bitcraze.

So until next time, fly safe!
