Support for walkera telemetry.

The two numbers on the bottom are 00002900000000000000f401 and 313233343536373839303132. The model still functions correctly.

That at least is good. It means one of the voltages is 4.1V. It also means that only half of the expected data is being received. I'll make another build that doesn't update the sreen so often that should help.

Here is a new build that will not constantly refresh the screen. Hopefully it will help. It doesn't really explain any of the other issues folks have reported though.

You will still need the filesystem from the above experimental release.

flint:
What model is it you are using? You seem to have one voltage (Voltage 2) which is what my Ladybird has, so I already know that position. But you aren't getting anything in the 2nd line (which is where temperature is sent) (the 313233... is the initialization value)

The display issues are at least partially due to not getting the proper fonts. I'm not sure what that is about. they work in the emulator, and I haven't changed the font code since the previous release where they were working.

Can you verify the dfu from here:
www.deviationtx.com/forum/5-news-announc...l-build-fab82a525bdb
just install the dfu, keep the filesystem you already have.
that build doesn't have telemetry, but it does use the new font code.

With this firmware bold fonts appears only for models with DEVO protocol. With all others protocol all looks normally. I've made reload after each change of protocol.

Ok, try this then. I found a buffer overflow in the devo initialization that may explain the font issue.

This should fix that problem:

Ok, so now I need folks with different configurations to try this out.

Use the filesystem (specifically the media dir) from here:

with this dfu:

Strange behaviour of temperature sensors. Temperature sensors changing for some time after I heat up T1 sensor, next they freezed. Seems I need to exceed initial value 31 (29C) to start. Value of T1 sensor doesn't changing, always 29C (31...).

The only way to get it to bind again is to turn off both, turn on tx, then turn on ladybird. This was not the case before, you could turn off either one and have it rebind when turned back on without having to reboot both.

I also have such behaviour with telemetry module and Fixed ID.

Also, if I press 'Exit' button at telemetry page, Tx reboot with beep.
