Testing a DIYDrones magnetometer in HK's GCS

Testing a DIYDrones magnetometer in HK's GCS from Pete Hollands on Vimeo.


I test the DIY Drones magnetometer ( HMC5843 magnetometer breakout board ) using Happy Killmore's Ground Control Station connected using SERIAL_UDB_EXTRA telemetry format, to a UAV DevBoard V3 running
MatrixPilot (revision 729 of trunk).

@Bryan. Very Cool. That's super to see these GCS's being put to good use.

 

BTW: Bill gave some simple and good advice. When positioning the magnetometer, and checking for motor effects, it's best to have an ordinary old fashioned hand compass in hand.

Hi!

 

Do the Vista issues persist? In case yes, can you give me the COM port number you were trying to connect to? We're using it on XP, Vista and Win 7, so there should be no issue.

And another question: Do you see any data in the debug console window when connecting the serial port? If you select the right serial port from the drop-down, you should see some kb/s indication and raw data.

Hi pixhawk,

I was using COM port 9 on my Vista laptop and getting data on the debug console window.

I just tried it again and it's working. My only guess is I was doing the wrong sequence of operations?

It didn't work on my first three tries. If I figure out what went wrong, I'll post it. Anyway, here is a picture of the GCS running successfully on Vista......

Well,

I just tried running the same test again and I couldn't get the serial connection. I had to go into the Vista device manager and disable/enable the com port and that did the trick.
