Not getting any data readout with APM 2.4 and latest HK lite

Hey all,

forgive me if this has been addressed already, but i haven't been able to track down an answer in the previous issues posted here. I trying to run APM 2 with the stock firmware from the APM Planner MAV 1.0. When i connect via usb using APM Planner, i have no issues connecting, getting data, etc. When i go to run HK v.1.1.35, I select ardupilot mega, then connect, and get gibberish, until eventually the connection fails and it defaults back to gluonpilot, and continues the strange stream... Attached is a screenshot of what i am seeing....

On a side note, i am also looking to use HK for data analysis of flights using other programs, and was wondering if someone could send me one of their flights so i could look at the log file formatting and get a better idea of how post analysis works with HK....

Thanks, and my apologies if this has already been addressed. 

Chris

The initial number in the .hko output file is VB.Net's Now.Ticks. Not sure what the starting date is or if it's seconds X10^-7 or what.

Times below are EST (I think we're at UTC -5)

 

"Ticks = 634782192287271568, Time = 7/18/2012 2:40:28 PM"

"Ticks = 634782192307282713, Time = 7/18/2012 2:40:30 PM"

"Ticks = 634782192327303858, Time = 7/18/2012 2:40:32 PM"

"Ticks = 634782192343254770, Time = 7/18/2012 2:40:34 PM"

I use this in VB.Net to convert it back to a date and time.

dDateTime = New Date(Now.Ticks)

All these variables are obsolete.

TSP: Throttle Set point

RSP: Roll Set Point

PSP: Pitch Set point

TTH: Throttle in 100% the autopilot is applying.

CRT: Climb Rate in M/S

I seem to be having this exact same problem although I'm finding it difficult having read through this thread to establish what exactly the issue was and the steps to resolve it?

Do I need to use Mav 0.9? If so then do I need to downgrade my firmware by doing the APM Setup (Plane and Quad) using the Mission Planner 1.2 mav 0.9?
