We don't recommend that people use the code in the SVN repository at this point. It's changing daily and often has not been tested--it's really just for the developers. Once we test a build properly, we move it to the zip file.

We're in the alpha testing phase, so please be patient. We should be in beta within the month.

Do you know if the ArdupilotMega APM_ADC_test prog works correctly as I am getting values of about 1595 for the temp and around 2000 for the rest of the sensors even when stationary? I read a post from Julio that I should be downlaoding the latest version of the libraries.

I'm on a plane now but I can create a new zip file of the latest libraries when I land tonight.

Hi Peter,

Not sure if it helps but this is what I get:

2038,2033,2471,1669,1673,1675,1683,2869

Make sure to use the latest version of the test program. I have seen at least two
(I think the right one has baud rate 115200)

Yes Andre that looks about the sort of numbers I got. I couldn't understand why I got those numbers when the manual says
"When your APM is on a table, the Z accel reading will be high, while the X and Y are near zero. That's because it's measuring the force of gravity, which is an acceleration (9.8 m/s^2). When you rotate the APM sideways or vertical, you'll see that reading shift to the X or Y, depending on which one is now measuring"down"."

So I was expecting some much lower numbers.

Peter, that's my fault. I was referring to the actual gravity readings after corrections. I'd forgotten about the ADC test, which is just analog voltages. I'll correct the manual.

If you were to tag the repo once you're done testing and ready to cut a zipfile, those of us following along at home would have the best of both worlds. (I see that you're currently not tagging...)
