Hello All,
Has anyone looked at the MB-LPS-01 series of differential pressure sensors by Microbridge?
There is quite a lineup in sensitivity/range (see spec sheets attached).
I'm looking for an air-speed sensor appropriate for a low-speed UAV (say, 15

I was having trouble getting my APM to read the RC signal. I thought it might get fixed by re-uploading fresh code and running the setup, so that's what I did. But once I updated the code (using mission planner), I found that my APM

I have tried to takeoff with a motor disconnected but the copter was not able to lift and it flipped inmediately.

So now, we have to buy USB Capture Card, li

The main advantages, from what I read, would be that:

i want in my program to run 2 separate loops -

to do this i set up 2 timers (using the Atmega

When compiling for arduino mega 2560, It gives this memory report:

Any pointers to reducing the code size so it will compile for atmega1280?
