Crazyflie Programming

[asaddler]

I am completely new to electronics in general but I am excited to work with the Crazyflie for a project. I am lost in programming the Crazyflie and I was wondering if someone could walk me through it. I already have the Bitcraze Virtual Machine working and I just need to know each programs' roles. Also, I am curious how you can incorporate code from GitHub into the Crazyflie. Thank you in advance and I appreciate any help.

Hi,

We just discussed this and realize that we don't really have a good overview of how the different software fit together. So we will try to document this with an image on the wiki, but for now here's a short run-down.

• crazyflie-python-clients: PC side client used to log/control the Crazyflie and also update the firmware. Also contains a Python API that can be used for other applications
• crazyflie-bootloader: Bootloader that runs at power-on of the Crazyflie. This allows updating the Crazyflie application firmware via the radio
• crazyflie-firmware: Crazyflie application firmware
• crazyradio-firmware: The firmware that runs on the Crazyradio USB dongle and allows communication with the Crazyflie. This repo also contains scripts for updating the firmware in the Crazyradio dongle
• crazyflie-android-client: This is an Android application that allows flying from a device that supports USB OTG that allows you to connect the Crazradio

Aside from these there are also Java, C/C++ and Ruby APIs (among others) available on GitHub that are developed and maintained by users.

Most users are interested in the Crazyflie firmware or the Crazyflie python client. The source-code for both are available on GitHub and in the Virtual Machine. Here's a short video tutorial on how to rebuild and flash the Crazyflie firmware:

Thank you, this clears things up a little, I appreciate the help

Hey.
Is it possible to write a code to program the crazyflie to communicate with an nrf24l01 using an arduino?

Bitcraze did a hack a while back that made the Arduino communicate with the Crazyradio through the radio's serial port. Unfortunately there is no further documentation on the effort yet...

Hey. Thanks for the reply. We got it working by using the code initially provided by tbitson:

Happy to hear you got it working! Good luck!!
