Re: Crazyflie Not Landing on Specified Coordinates

Hello sbradley!

How to answer this depends a lot on what positioning system you are using! For an overview and comparision of the different kinds, please see this video: https://www.youtube.com/watch?v=lkEHKmEvcB8

Re: Multiple Multiranger decks in a Staggered Configuration

Hi shreeram! So, this might be possible :) It is not something we have tried, I will attempt to answer your concerns! Using two multiranger decks together is not compatible without some patching. The IO expander on the decks will have the same I2C address. You can fix this by patching the address pi...

Re: Problems of using AI-deck and SD-card together

Hi WendaZ! You are doing it correctly it seems, it is just one bit that needs fixing that I did not think of! The firmware checks at startup that no pins are allocated by multiple drivers, the checks fails, as you see with the message: DEBUG_PRINT("ERROR: Driver Gpio usage conflicts with a &quo...

Re: Problems of using AI-deck and SD-card together

Hi WendaZ! So the conflict seem to be the IO_4 port. It is used in the AI deck to reset the GAP8 processor and in the SD deck as chip select for SPI. It seems we are a bit over optimistic in the compatibility matrix. It _is_ possible to use the SD card deck and the AI deck together, but it seems you...

Re: On-chip debugging VS-Code Ubuntu 20.04

How does your settings.json look like?

Perhaps you need to add:

Code: Select all

"cortex-debug.gdbPath": "gdb-multiarch"
Or "/usr/local/bin/arm-none-eabi-gdb"

Re: On-chip debugging VS-Code Ubuntu 20.04

Hello WendaZ!

As a first step could you verify for me that you have the arm-none-eabi-gdb binary on your system?

It should probably be in /usr/bin/arm-none-eabi-gdb ...

Could you also paste the contents of your launch.json here? Thank you.

Re: Command Based Flight Control doesn't work

Hi! In your cfclient config (mine was found at /home/jonasdn/.config/cfclient) there is a field "input_device_blacklist", the names there are checked against the devices found: [...] if len(Config().get("input_device_blacklist")) > 0: self._dev_blacklist = re.compile( Config().ge...

Re: Random Flyaways and Flips

Thank you!

This matches what we have seen! I am in the process of trying to setup some tests to catch this out! All findings you can share would help!
Would you be able to test this with some other positioning system? To see if it is Lighthouse specific?

Re: rewrite the firmware to change the control law

Hi!

There is no quick answer to this, perhaps you could start by watching the excellent intro by Kimberly on Youtube:

Re: Battery Logging with Example Script

This is more of a Python question unfortunately, you will have to keep learning and dig at it! But, I would say, maybe a better approach would be to set up asynchronous logging callbacks (see this guide: https://www.bitcraze.io/documentation/repository/crazyflie-lib-python/master/user-guides/sbs_con...
