deviation-devo F12E

No, I think supporting one GUI will be more than enough work. Now that I have more experience with it, a full graphical GUI is probably beyond the capabilities of the TW8816 anyway. However, It will still be a lot more flexible than the devoF7.

Here is my test of the XY-Graph function:



It isn't possible to do arbitrary graphics anywhere on the screen, but there are 3 available movable 'windows' available which can hold graphics (the 4th window will be configured for full-display text). These windows require a lot of RAM to use, so I'm trying to keep them small, but We can probably do small bitmaps for the model icon, and things like the xy-graph. I think bar-graphs can be done using the standard text window (like djtrance is working on for the devof7).

Agreed, the F12E is really a much better transmitter than the F7. It even has a 16 color OSD. With a larger memory it would be even better, but I think we'll be able to manage with what it has. However I am still convinced that using the 'text' display for the 12E and the F7 is the best solution. I still have some more work to do, but I'll soon turn in the f12e changes which will let us share most of the code between transmitters. Of course the F7 doesn't have uploadable fonts, so it can't do the graphics, but we can conditionally turn those on with defines. Walkera also has a Devo F7DS which seems to have a digital screen and may use a better display chip so maybe we'll be able to put graphics on that some day.

A bit more progress. Here's the trims and the image support:

Well, I added support for toggle icons now, so the GUI is basically fully functional. My next task will be getting video enabled. Once that is working, it should be ready for testing.

Even still, there is a quite a bit of work to do:
Enable the 'Standard' GUI
Add visual alarms on the main/telemetry pages
clean up some of the display pages
Determine the best way to overlay text over the video screen
Figure out how to let the user interact with the filesystem

But progress is good so far.

I thought some folks might be interested in this (sorry for the terrible quality):



Deviation is basically fully functional on the 12E now. As I said above, this isn't the end of the line, but it should be very usable as it is now.

I added a new video page. it will allow you to assisgn a toggle to the video (to easily turn it on/off) as well as select the video channel.

I have now merged the F7 and F12E code into the trunk. Nightlies should include support for these transmitters now. However, it is still very experimental. Loading the filesystem is a bit tricky as well. I'l post instructions once I have written them.

I don't know what frequencies are actually supported, but there are 16 combinations, and Walkera's firmware only exposes 9. Deviation provides all 16. If there is some way to calibrate them (using a transmitter with variable but known frequencies) we could find out.

you will need to know what firmware you have. I don't know if the 1.2 firmware is available, but the 1.3 and 1.5 firmwares are. You cannot save your firmware, so you need to find the firmware you want on Walkera's site or walkera-fans.de.
You can backup and restore your configuration and models though.

You will need to use the deviation-upload tool (instead of Walkera's tool) to upload firmware the the F12E. That tool will also allow you to backup your models. However, I haven't released the version you'll need yet. Probably sometime this weekend it'll be available.

Does it really? I traced the wires, and I can only find 4 wires => 16 channels. Maybe I was thinking about the F7 when I said it had only 9 channels. I'm sure I maxed out at 9 somewhere along the way. Has anyone verified if the upper 16 channels are just duplicates of the lower 16? The Receiver board only has 4 channel pins so I'm not sure how you could get the extra 16 channels with the way it is wired.
