Ok, after some delay, I'm going again.
I added a new 'trim' settings page, as well as a 'main page'.
New features:
* support for very large fonts
* Initial menu for setting up trim values
* Main page will show live trim and throttle values

I've decided that rather than implementing everything that we'll eventually need, that I'm going to start working on getting basic functionality to the point I can actually control a model from the transmitter.

So my next step is to start work on a radio interface. I'll probably start with a protocol I already know (likely the FlySky protocol) since the effort to reverse engineer the DEVO protocol is substantial, and this is not my field of expertise). With any luck, rcH4x0r will come back at some point to help with that.

Welcome back! :)

I have started the testing.
How ready is it supposed to be?

Minor bug: I cannot step throw the trim page with "5", only if I open and close one of them.
Probably there is some memory leakage, because the app crashes after some window opening. It crashed after 42 trim window opening, or 19 channel settings window.

More coming later... ;)

Well, it is only lightly tested. I just added a quick change to let you change the steps from the main trim window rather than entering the edit window. Once configured, it is unlikely you'll ever need to change the trim buttons for a given channel.

The trims are not actually connected yet, so they won't affect the outputs you see (except for the heli-mix controls where they will affect the output, but not in the proper way.

If you didn't figure it out:
use caps 'A'/'Q' for changing the throttle trim, and 'S'/'W', 'D'/'E', 'F'/'R' for the other corresponding channels. You should see the trim bars move on the main page.
keys '5' and '6' move through the different pages now (that will likely change soon)

Edit: And I fixed the problem with not being able to cycle past the trim page. The memory leaks will need to wait until later for me to look at.

I don't see the trim bars moving at all.
The values on the right pane and the throttle value on the main window do change, but not the trim bars. Furthermore, the trim steps seem to be always 20%, not the value set on the trim window. Actually whatever channel's trim settings I open, it always show the throttle trim settings.

Entering edit mode on the trim page should work now.
I haven't been able to reproduce a crash, and I ran within valgrind and didn't see any memory leaks

the trms work for me. use shift-a, shift-q to move the throttle trim. It won't woirk with caps-lock for some reaosn, you need to actually hold the shift key.

Sorry, it's my bad, I somehow missed the word "caps". :oops:

Now the trim bars are working, but I have two observations:
1. If the trim step is not a divider for 100, and I step throw the range comletely, then in the last step it makes a half step to 100%, but then going back it goes throw different values and never hit the 0%.
2. Long press doesn't work like on other numeric spin buttons.

It still hangs for me if I open too many windows. It doesn't actually crash, but don't refresh the screen and the controls won't work. It always happen sooner or later, while I am testing...

for the hang, the easiest way is to use gdb to provide me more info:

from the console:
gdb ./emu_devo8
r
<test the emulator until it hangs>
in the console again:
ctrl-c
bt full

then you aren't in gdb.
Assuming you are using MSYS for your console, you should have gotten a prompt that looks similar to (but probably not identical to):
Program received signal SIGINT, Interrupt.
__mpn_cmp (op1_ptr=0x7fffffffdb90, op2_ptr=0x7fffffffdb50, size=2) at cmp.c:46
46	cmp.c: No such file or directory.
	in cmp.c
(gdb) 
when you hit ctrl-c within the gdb window

I can't easily give you instructions on how to get gdb working (it should just work) but some searching on the web will hopefully help.

The backtrace was interesting.
It shows that the code was unable to find the file "images/btn48_16.bmp" which shouldn't happen.
In any case, it tried to just draw a black rectangle, but the requested size was > a 16bit value which caused an overflow that hung the system.

I've committed a fix for that specific issue, but it doesn't explain the underlying problem. Please build the latest code and see what happens now. If you see a similar crash or hang, you can send another gdb trace.

Ok, I finally figured out what was going on and was able to fix it. There was a file-handle leak which was resulting in too many files being open at once. That caused it to appear that one of the images wasn't present which triggered a different bug which resulted in the crash.

By the way, how did you kill the app such that you could get back to gdb? I tried it in windows, and gdb does not work as it does in Linux. I was unable to get back to gdb after triggering the hang.

Great!

Well, I went one step further the first symptom of hanging (clicked on the already not visible button again), and then it crashed even more (while still visible) and returned to the prompt.
Then it wrote the "Program received signal SIGSEGV, Segmentation fault." message. You can see it in the output I gave.

P.S.: How do you like the modded design and larger editing font?

Thanks, it should be fixed now.
I have been implementing the interrupt code that controls the radio. I need the code to work in the emulator so I can verify that the code sequences are correct. Unfortunately the code I use in Linux doesn't work in Windows, so now I need to compile 3 times: linux, windows, devo8. It is getting more challenging to keep the compile clean everywhere.

As you noticed, I changed the keys again. the new keys match the devo8 buttons. So now you use left/right/up/down/enter/escape to control everything
