Re: Configuration of LPS

Oh, easy solution, thank you! Thought there is a problem because in the getting started guide the pictures are different from what I got to see.

Re: Configuration of LPS

All leds (TX, RX, SFD, RXOK) are flashing, if that can help. In cf-client, all anchors are green (twr) and the console displays "ESTKALMAN: State out of bounds, resetting" every 30 secs approx.

Configuration of LPS

Hello I've been trying to use the lps system but it's not working at all. I installed the firmware with "git clone --recursive https://github.com/bitcraze/lps-node-firmware.git", "make" and "dfu" and set the IDs and mode "Anchor (TWR)" with the lps tool (in windows). But when I'm starting everything...

Re: Update frequencies of sensor signals/states

Ok, but I think the update frequencies of stateEstimateZ az, vz and z differ among each another. So it's probably not the same frequency as the estimator_kalman is running at, I guess? I want to simulate signal-noise, so I need the exact update rates of stateEstimateZ az, vz and z when using flow-de...

Re: Update frequencies of sensor signals/states

Thank you for your help! But another question occured to me recently... I am using the flow-deck and I noticed that frequencies of acceleration, speed and position (stateEstimateZ az, vz, z) are different than without flow-deck. Where can I find these frequencies? That would help me a lot. I already...

Re: Update frequencies of sensor signals/states

Thanks! Do you know where I can find the definition (1 kHz) in the code?

Update frequencies of sensor signals/states

Hello, as I can see in https://github.com/bitcraze/crazyflie-firmware/blob/master/src/modules/src/estimator_complementary.c#L44, the attitude update rate is 250 Hz (angle Pitch/Roll/Yaw) and position update rate is 100 Hz (X,Y,Z). But what are the update frequencies of the sensor signals, e.g. angul...

Re: Timer configuration (Interrupt service routine)

Thanks Arnaud, maybe I will try to configure TIM6 then. And if it's not working, your Idea with using sleep seems sufficient as well. Thank you! Didn't know that the Microcontroller is that fast ...

Timer configuration (Interrupt service routine)

hello, I need to configure a timer in order to get an interrupt every 1ms. So first I need to know which timer I can use. But I also don't know at which point I should configure the timer and where I can define the TIM2_IRQHandler(void). Does anybody know where I can find information about timer use...

Re: Accessing raw thrust channel values in firmware (PS4 controller)

Thank you for helping, Arnaud! I have not pressed the "assisted control"-button first, so that the "position hold" was not activated. But now it works and I can read the values. But for the second issue: Can you tell me, at which point in the crayzflie firmware the "pressed-buttons-signals" are read...
