Re: Difference between zRange.c and zRange2.c
The camera is an optical flow sensor. It essentially works like the sensor on an optical mouse and detects motion in x and y. The motion output form the flow sensor in combination with the distance to the ground (measured by the distance sensor on the deck) it is possible to determine how the Crazyf...

Re: Can not detect deck when using the step-by-step: motion commander guide
The best way to check if a deck is detected by the Crazyflie is to use the python client. Open the console tab and check if you can see a line saying something like "DECK_CORE: 1 deck(s) found" You can also use the Parameters tab to check which deck that is detected. Find the "deck&qu...

Re: Using v2 lighthouses facing upwards
Hi Joe! As mentioned earlier, the geometry estimation script is designed for a CF placed on the floor. Any other use cases may produce unexpected results and I do not know what to expect. The script I provided for multiple geo measurements was a quick hack to try out the concept, there are no guaran...

Re: Using v2 lighthouses facing upwards
Hi! If we took three readings from get_bs_geometry.py in three seperate positions. we could chain the reference frames together right? (it has been a long time since I did engineering maths) Yes, as long as you have readings for (at least) two base stations in each position you can map the pose of a...

Re: Bad readings when using two basestations
It sounds like your geometry data may be wrong, have you set it according to the instructions? We are currently adding lighthouse configuration functionality to the client, and even-though we're not done yet, we have implemented a visualization of the system. If you update the firmware, python lib a...

Re: Bad readings when using two basestations
Hi! Have you configured the base stations to use channels (modes) 1 and 2? This part was unfortunately missing in the instructions but was added recently. You can find the instructions here https://github.com/bitcraze/crazyflie-firmware/blob/master/docs/functional-areas/lighthouse/setting_up.md#ligh...

Re: My Crazyflie won't hover
No worries!
There are no stupid or bad questions. We want everyone to learn and evolve, regardless of the level they are on.
Have fun!

Re: Using v2 lighthouses facing upwards
1) Valve is using the values 1 to 16 when configuring the channel in a Lighthouse V2 base station. It is also possible to set it to 0, but that means "detect which channels that are used and pick one that is unused", and this feature should not be used with the Lighthouse deck. On the othe...

Re: Using v2 lighthouses facing upwards
This is not really supported (which makes it more fun of course) If you increase PULSE_PROCESSOR_N_BASE_STATIONS to say 4, the Crazyflie will support 4 base stations, using channels 0-3 (1-4 in the lighthouse GUI). Everything else is identical to 2 base stations. For the get_bs_geometry.py script, t...
