"I think that the key issue to note here is that APM Planner only freezes when I press 'enter ' in the Terminal/CLI screen.  It definitely seems to happen with certain APM2's more than others.  I haven't tried it yet on a different computer, but…"

"I'm running Arduplane 2.40 and I'm getting the same thing on multiple boards.

I think that the recent firmware might have a bug?  But I'll try some of the suggestions listed here."

"Okay, I think I have it figured out.

I looked up the GPS datasheet, and on page 14 it suggests that the time is output in the format hhmmss.sss - I examined the numbers I was getting using this format, and it still didn't make sense - the last data…"

"Have you followed the instructions here?

The first things that come to mind are to a) ensure that you're using the right version of Arduino (there's an arduplane-specific version mentioned in the link above), and b) check that the arduplane folder…"

"Yes, as far as I can tell, that's all that needs to be done.

I've been using the simulator to try and test some code I wrote within arduplane, but it's not being recognized by the simulation (but it does work in real life...)

Are you simulating…"

"Hey, I'm taking a look at where you talk about using the APM_RC.InputCh(CH_x) method to get radio input.  What's the difference between that and g.channel_xxxx.radio_in?  Do they produce the same integer value that can be fed to the outputs?"

"I've now determined that custom_mode exists in the code.  Perhaps I need to take advantage of this feature to implement my custom code without overwriting FBW_B.  Can anyone give advise on how to do this?

Thanks!"

"Well, I've gone through ArduPlane.pde (now changed to ArduPlane.ino by the latest version of Arduino...) and I've managed to figure out that the update_current_flight_mode() function doesn't change the operation of the servos, even if it's disabled…"
