As you might expect, we use the Crazyflie python client a lot at Bitcraze. The client has a lot of features, ranging from setting up LPS/Lighthouse systems to turning on/off the headlight LEDs on the LED-ring deck. But some of the features we use the most is probably the console view as well as the logging/parameter subsystems. A lot of the time we modify firmware, flash it and want to tweak (via parameters) or to check if the changes are working as expected (via the console or logging). Then switching from the terminal, where we build/flash, to the Qt UI in the Crazyflie python client can be a hassle if you just want to do something quick. It would be great to be able to log/set variables directly from the terminal, well now you can!
Meet the Crazyflie command-line client, a fun Friday project I worked on a while back. The CLI is written in Rust and was made possible thanks to a previous fun Friday project by Arnaud on the Rust Crazyflie link/lib, which has now moved to the official Bitcraze repositories. The CLI project is still very limited, but has some basic functionality:
- Scan for Crazyflies and pre-select one to interact with
- List loggable variables, create log configurations and print their value
- List parameters and get/set them
- Show the Crazyflie console
Last week the first version, v0.1.0, was released on crates.io. So if you have Rust set up on your computer and want to test it out then all you need to do is to type “cargo install cfcli“. The CLI still only has some basic functionality, but hopefully it can be expanded in the future with more useful things! Feel free to leave any issues or comments you might have on the Github page.
