Re: Range Values freezing

This is gonna sound a little stupid but we realised that the problem arose because we were tapping the 5V pins and Gnd pins for a FPV camera. So the camera was competing for power with both decks. The problem was solved when we removed the FPV camera!

[SOLVED] Range Values freezing

Hi, I have this issue on my bolt drone(with flow deck v2 and multiranger deck) where the range values from the multiranger deck and the z-ranger values would stay at the same value and freeze. Sometimes it happens right at the start, sometimes it happens mid-flight, which caused a few crashes. When ...

Re: Drifting in x & y direction while yawing about the drone's center

Hi Kimberly, Thanks for the prompt reply and for moving this topic to a more appropriate group! The flow sensor, namely the VL53L1x by pixart imaging, only outputs a single xy flow vector. I think you meant PMW3901 here, not VL53L1x :) Long story short, there is no way to fix this with this current ...

Drifting in x & y direction while yawing about the drone's center

Hi, I have a Crazyflie Bolt drone with a flow deck v2. I notice that the drone drifts in the x-y direction when I try to yaw about its center. Is this a known problem/limitation or is there something I am doing wrong? I tried yawing it fast and slow, and I have this observation- The amount of drift ...

Re: How to increase output frequency of multiranger deck?

Thanks! I added the lines

Code: Select all

      VL53L1_SetDistanceMode(&dev, VL53L1_DISTANCEMODE_MEDIUM);
      VL53L1_SetMeasurementTimingBudgetMicroSeconds(&dev, 25000);
and I was able to get around 20hz now.

How to increase output frequency of multiranger deck?

I see this line in multiranger.c : vTaskDelayUntil(&lastWakeTime, M2T(100)); I decreased it but the maximum frequency I can get seems to be around 15hz only. Meanwhile, in this thread(viewtopic.php?t=4764), I see that the developers were able to get 25hz. How do I increase the output rate of the...
