Re: CF Bolt Motor Override Signals

The Mx_OVERIDE signals was intended to have a dual purpose if one rather run brushed motors but it has not yet been implemented. Instead they are enabling power to the connector and thus to the ESC if it is cabled using the connector. So in the current functionality the naming Mx_ENABLE is much more...

Re: Multiranger deck I2C(frequency )

It is probably a parallelism problem. The Crazyflie is starting the reads in parallel and my guess is that the Arduino is doing it in series and that is why you get a low update rate. On the Muliranger deck the default setup is 10 times/sec for the 5 tof sensors but I'm pretty sure we have tested it...

Re: The type of the AI deck and the colored camera

There is currently no good function to retrieve the color image, and one problem is that the image is JPEG compressed on the GAP8 side which loses some of the information. Otherwise it would be possible to do the Bayer conversion on the PC side but now it is not that good. Here is an github issue ab...

Re: The type of the AI deck and the colored camera

The AI-deck says AI-deck 1.1 on front and backside. If it only says AI-deck it is the 1.0 version.

Re: Bolt Tuning

Tuning can be challenging and something we want to improve. Hopefully soon! 1. You started in the right end. Start with the rate PID values as these has the biggest effect. The attitude PID values often doesn't have to change that much. 2. The kalman filter tuning is a bit easier now and you just ha...

Re: A problem in using ARM-USB-TINY-H and ARM-JTAG-20-10 and setting up the GAP8 SDK

Yep, USB type B might not be so common anymore, good idea, I've added that.

The GAP_SDK is big and not yet that easy to work with. Have you tried the docker variant? This I think is much easier to get started with.

For me the ARM-USB-TINY-H and ARM-JTAG-20-10 are "keyed" to know how to connect them, are they not for you?

Re: FPV Flight Hardware

I'm not an FPV expert but to me it looks like the camera you linked to will work. It says 3.3-5V where 3.3v could be on the upper edge. If doing to quick accelerations, there can be battery voltage dips as low as 2.8V. If flying smoothly I think it will be fine. The FPV camera will need a separate r...

Re: Crazyflie Bolt, one of the motor outputs is not working.

The connector contains VBAT - SIGNAL - GND so the signal can be accidentally shorted to either of these. Shorting to GND shouldn't be any problem but shorting to VBAT could be destructive. I think the GPIO is broke on the STM32F405. Please send us an email to support(at)bitcraze.io and we will help ...

Re: good propeller test values

Do you have two crazyflies so you could compare? We have seen some rare cases with bad IMU (BMI088), but it often has problems leaving the bias calibration state in the startup then. Have you tried logging the lighthouse angles or the position during the startup to see if there is a outlier or simil...
