Could that function also be used for ultrasonic height stabilization from the firmware itself?
After I built my ultrasonic extension board and being able to query the board from the firmware, I never got around to implement the actual height stabilization because I didn't know how to get started...

Re: Need help in scheme
They used KiCAD.
Here are the schematics: https://wiki.bitcraze.io/projects:crazy ... schematics
Can't find the KiCAD sources for the Crazyflie itself though.

Re: [SOLVED] Selecting an ultrasonic sensor and interface
Haha, yeah. I kept the solution in the basement for a day to be re-used. Afterwards all those mosquitoes were in it. Something probably attracted them.chad wrote:Wow dbrgn. This is cool. The best part is seeing dead mosquitoes in the sodium persulfate solution. Be they didn't know what hit 'em...

5V Tolerant GPIO Pins
The datasheet for the STM32F405xx mentions "Up to 138 5 V-tolerant I/Os". Unfortunately I can't find any more information on them. Are the GPIO pins (specifically IO_2/PB5) tolerant to 5V input? Edit: According to page 57, the pin is listed as "FT" which should translate to 5V to...

Re: Programming the EEPROM
Here's my script to flash the 1-wire memory using CRTP: https://github.com/dbrgn/crazyflie-clie ... -memory.py
There seems to be a problem though, it does not work yet: https://github.com/bitcraze/crazyflie-c ... issues/166

Ah, found lib/cflib/crazyflie/mem.py in the crazyflie-clients-python library. Working on a commandline tool now

Programming the EEPROM
Are there some tools in the CF2 firmware to flash the DS28E05 EEPROM on a custom expansion board?
I saw that modules/src/mem.c seems to provide that functionality. How can I use it?

Re: [SOLVED] Selecting an ultrasonic sensor and interface
I also finished my attempts with the HC-SR04. I etched my own PCB (for the first time) to be able to use the SOT23 voltage converters.

Re: Kicad library problems
I can't quite get it to work yet. Steps I did: 1. Re-checkout the project 2. Load the schema, add the no connect flag to all pins 3. Delete Bitcraze icon to prevent it from showing up in the netlist 4. Do the electrical checks, all pass 5. Load the netlist to check that all parts have a footprint as...

Re: Kicad library problems
I'm also having troubles. Is the KiCAD layout project on Github missing the footprints library?
The project contains the following library reference:
That directory doesn't exist though. Therefore pcbnew cannot find the BF090-10-X-B2 footprint.
The project contains the following library reference:
Code: Select all
LibDir=../kicad-libs/footprints
