Re: IMU Sensor Upside down (specific lines to modify)

The 2.1 uses another IMU (BMI088) and flipping the IMU axis was done in the driver (could have been made higher up) so this needs to be done in the sensors_bmi088_bmp388.c for the CF2.1 static void sensorsTask(void *param) { ... /* Gyro */ sensorData.gyro.x = (gyroRaw.x - gyroBias.x) * SENSORS_BMI08...

Re: Issue with Crazyflie with BigQuad, Loco and Z-Ranger v2 decks

Hmmm, good question which I don't really know the answer to. Why it fails on the first BiqQuad deck is probably because of this: DECK_INFO: ERROR: Driver Gpio usage conflicts with a previously enumerated deck driver. No decks will be initialized! DECK_INFO: ERROR: Driver Periph usage conflicts with ...

Re: Crazyflie issue with loco position

I think this got solved in the email right? It was a miss-configuration of the system if I remembered correctly.

Re: Why the value of "MAG_GAUSS_PER_LSB" is 666.7

You might be on to something. I think this code originally comes from somewhere else so can't really answer why it is 666.7. I guess it hasn't caused a problem as it normally is the heading that is interesting.

Re: Flowdeck v2 failing calibration with CF 2.1

Hmm, 100% with the CF2, that puzzles me... Then at least we can rule out a problem with the Flow deck v2. The z-ranger needs VCC, GND, SCL, SDA from the CF2.1 deck connector . Do you have the possibility to check if these connects well? I kind of expect VCC and GND to work as the flow sensor initial...

Re: Hover with flow deck shaking and goes crazy

It could be something with the HW but it sounds more like the flow has problem tracking. One problem with optical flow is that it needs lighting and features to track. The algorithms are not perfect and especially error handling could be improved a lot. The laser ranger sensor on the other hand send...

Re: FLOWDECKV2's setup

Can you post your console output, similar to what is done in this thread. Did you mount the flow deck the right way?

Re: Flowdeck v2 failing calibration with CF 2.1

There is something wrong with the I2C buss, possibly caused by the z-ranger sensor or connection problem. ZR2: Z-down sensor [FAIL] To rule out connection problem could you inspect the two I2C pins (SDA, SCL) in the connectors. If it is not connection problem we can fix we will arrange a replacement...

Re: Lighthouse positioning is not reporting any location

How does the LED sequence on the lighthouse deck look like? During normal boot red and blue led should go on and after that red should turn off so that only blue is lit.

Do you get any reasonable values from the lighthouse.angleXX logging variables?

Re: Connecting flowdeck2 hardware

I still don't get it, connection the flow deck to the crazyflie is pretty simple. You want to connect another way, though wires?
