APM2 I2C Connector
Started Jul 20, 2012 0 Replies 0 Likes
The APM2 has a four pin connector for the I2C port rather than the six pin connector on the APM1. Are there any cables available with the mating four pin plug? Failing that I have thought about…Continue
X-Plane interface
Started this discussion. Last reply by avionics Aug 16, 2011. 8 Replies 0 Likes
I have been trying the x-plane interface over the last couple of days and could't manage to tune the airframe - it always ended up spiraling in after switching to any of the stabilized modes. This…Continue
RTL vs.Loiter
Started this discussion. Last reply by Luke Jun 23, 2011. 6 Replies 2 Likes
Is there any way to distinguish between RTL and loiter via the Mavlink? From what I can see, when an RTL command is active it is implemented as a loiter at the home position, so the flight status…Continue

You forgot including the AM/PM field in your program, times are not in 24h format in the input txt files (unfortunately)
Actually, it would be better writing YYYY/MM/DD HH:MM:SS.xxx in 24h in your csv files.

Extracting data from tlog files for plotting in Excel
Posted on May 11, 2012 at 6:00pm 47 Comments 5 Likes
I wanted to analyze some data from a tlog file and figured that Excel would be the most flexible way so I created a little utility to extract the data I was interested in and save it as a comma separated value (CSV) file. Each selected parameter is in a separate column, and Excel can open the csv directly.
Note that it can't open the tlog file directly. You must use the Mission Planner to convert it to txt format. so:

Ardupilot control using OSD menus
Posted on January 4, 2012 at 3:06pm 4 Comments 0 Likes
I would like to fly with live video and goggles, but this makes it tough to make any changes on the mission
planner. To avoid any need to take off the goggles I integrated a series of menus in the OSD.
My setup, as reported…
Continue Ardustation as a terminal
Posted on August 12, 2011 at 10:00am 14 Comments 6 Likes
While the progress on the APM Mission Planner makes it more and more attractive to bring the laptop out to the field for each flight, sometimes the simplicity and sunlight readability of the Ardustation is what I really need. The problem was that I kept adding more pages and busted the memory limit of the…
