Re: VL53L0X stand-alone and forcing drivers
Spaces would not have worked without adding quotes around it anyway since CFLAGS is passed as argument to gcc during the compilation. Rather than handling space in the firmware (which tend to be a non-trivial task in embedded C), I think this should be handled by better documentation. Maybe adding a...

Re: Send Thrust, yaw pitch roll command and only use attitude PID controller
Hi, You can send roll/pitch/yaw/thrust (RPYT) setpoint to the Crazyflie. To answer your questions: 1. The setpoint structure comes from the commander subsystem and is filled up with the latest setpoint received from the radio. There should be no significant delay between receiving a new setpoint ove...

Re: lighthouse-fpga Code on UPduino(UP5K) and HX8K Dev. Kit
That sounds great! I will test the PR and apply it if it works on the deck then. Thanks for the PR!

Re: Acceleration Setpoint Crazyflie Python Lib
Hi, There is no commander packet implemented yet to control only the acceleration. Though, the commander subsystem is quite flexible so it should not be too hard to add. The commander packets are declared there in the firmware: https://github.com/bitcraze/crazyflie-firmware/blob/8b0d1ab5db66bbd43f8c...

Re: Lh deck custom use
Hi, If you look in the git history you can find the version of the script that produced that input: https://github.com/bitcraze/lighthouse-fpga/blob/3b2c1c7a65c17b938039b6f9d858463d9f575fd9/tools/print_frame.py I would not necessarily trust that function though: we have had a lot of back-and-forth o...

Re: lighthouse-fpga Code on UPduino(UP5K) and HX8K Dev. Kit
Hi! Thanks for your answer. Unfortunately I do not have much clue of what could happen with the configuration. I is possible that there is a bug in the current implementation that makes it extra-brittle. For the 2 sensors, the reason for the requirement is to improve the range of measurements: when ...

Re: Lh deck custom use
That you had to send 0x00 is normal: the deck starts in bootloader mode and 0x00 is the command to start the firmware. The bootloader is documented there: https://www.bitcraze.io/documentation/repository/lighthouse-bootloader/master/bootloader-protocol/ To set the leds it should be enough to send "0...

Re: Modifying usbLinkTask causing queue error
Hi, One reason I can think about for this problem is that you are sending control packets from both sides: if the Crazyflie is receiving control packets both from USB and from RADIO, both will drive the motors. One way to test that would be to disconnect any gamepad on the computer that runs the Cra...

Re: Lighthouse positioning deck SPI usage
This is correct, the SPI pins are only used during production and the UART2 is only there as an option. The 0Ohm resistor are not soldered on production boards and so no connection is made to the Crazyflie SPI port. Only one UART and the I2C bus is connected to the Crazyflie. The Crazyflie is curren...

Re: How to communicate with the crazyflie using developed android app
Hi, If you have the AIdeck and want images, the best is to use wifi to communicate the images. The Crazyradio bandwidth is not so high. The AI-deck can be setup both as an access point or connected to your wifi network (see doc there: https://github.com/bitcraze/AIdeck_examples/blob/master/docs/test...
