Bitcraze flow breakout board with PX4
Posted: Tue Sep 08, 2020 11:51 am
Hello,
I'm trying to launch the your flow breakout board on the pixhawk4 system, There a few tutorials on how to physically connect the flow board tot he PX4, but basically nothing for troubleshooting, I'm not able to get the drone to hold the position, using this bitcraze flow breakout board.
I've been able to start up both of the necessary sensors, but the drone still doesn't seem to be holding the position, I've toggled all of the necessary parameters via PX4 that should result in indoors position hold, but nothing happens, and when inspecting the logfiles from the drone, seems like the drone is detecting correct movements with IMU sensor, but the output from the flow breakout sensors seems to be pretty much a flat line, on the graph, and if I enhance the scale of the optical sensor output by about 100x, the graph seems more like it should.
So I do know for sure that the distance sensor on the flow breakout board is functional and starting, the output from the distance sensor is correct, which could be messing up the calculations when not outputting the correct distance, but not in this case.
The quality output from the flow breakout also seems a bit jumpy, but still in the correct zone, I've also tried powering the flow breakout board from a separate power source, not the PX4(due to an article on this subject viewtopic.php?f=2&t=4345&p=19832&hilit=pixhawk#p19832 )
Not sure what else I've haven't tried already, perhaps someone can point me in the correct way, the PX4 community isn't helping much regarding this topic also, therefore, I'm asking here.
