Deviation for Devo F4?

pb, here are some bugs I found, there is no devo F7 nor F4 option on the bug tracker so I'll write it here and when it's added I'll post it over there

in the backlight option the numbers doesn't match the level of brightness:
'OFF' - not off
'1'- brightest
.
.
'10'-backlight Off

-Remote battery voltage read is significantly lower than actual voltage (in original firmware the read was 7.1 and on deviation 6.6)

-hold switch doesn't work, I tried coming back to original firmware and it was all good..

-couldn't find a way to assign switches and knobs (not necessarily a bug but I tried every menu and sub menu there is)

-couldn't find any reference to the AUX2 knob on the channel monitor

suggestion:
because DSMX is more common this days I think it will be better to include it instead of DSM2

once again thanks for all the hard work you put in this awesome project

You can select which protocols you,want. extract devo.fs, exchange dsm2 with dsmx, repack it to devo.fs and put it on the devo again. Read through the last 2 pages, there we talked about how to. Note: Fs has to be smaller than 60kb

@SirDomsen tnx!

done!

Hi,

I just added a few switches using an Arduino - works as expected. But Because of the boot-up time of it, it
s not very secure to use it as THOLD. So I decided to do the switch mod similar to the 7e one. I'm not really sure if I connected to the right spots on the Button-Board - but I can't even test it because if I comment in "extra switches =3x2" - nothing appears in the channel monitor. I thought even without switches there should be some info for Switch A and B? Perhaps the switchmod feature is not enabled in the F4 build? Could that been done?
Thanks in Advance

edit: Btw: Would it be possible to add one 3-way and 2 2-way switches instead of 2 3-ways? I know that it could be done by wiring only, but then there will be an unknown switch state if both 2-ways are "cloesed"... So perhaps some sort of "extra switches = 3x1, 2x2". this should lead Deviation to display A0, A1, A2, B0, B1, C0, C1. If possible, that would be really cool!!

If you can't figure out the THOLD switch and you just need it to be used always for making sure the throttle is at minimum, you can wire it up manually inside with a SPDT switch, with the centre pot wire going from the board to the centre pin on the switch, then one extreme of the switch to the centre of the pot, and the other extreme to the minimum pin on the pot (not sure offhand if it's the Vcc or GND wire, but the one the pot has as minimum... I assume GND). Then, with the switch in off mode, the middle signal wire is going direct to the pot as it always has done, and in the on position it will be going direct to the throttle minimum wire, independently of where the throttle stick actually is.

Extra switches show up now in the latest nightly - thanks for that. But I obviously dod something wrong with the wiring. Perhaps because I did not completely understand what the 7e switchmod does. I assumed that ext/ent button on the F4 are connected the same way to the mcu as on the 7e. Seems not like that... To which mcu pins should the extra-switch-wires lead?

Did you have any luck with the THOLD and FMODE switches at all in the end?

I did the mod with the diodes. I used 1N4148. At the moment I wired the A switch as a 3-way, the B switch as two 2-ways. But as you mentioned, that won't work out, did I understand correct? In that case, I'd prefer to use one 3-way and one two way. The rest of the switches will be wired using the arduino. I'll attach some pictures, soon! Thanks for your help so far!

EDIT:
Now i tested around a bit - With wiring as shown on the pics, I have somewhat of a reaction. Depending on the switch position, the devo does the trim sound. Unfortunately, the buttons don't work, I only hear a trim click sound while trying to hit ent/ext or one of the +/- buttons...

Maybe this will help...

Removed by PB because it is wrong

I don't think they would have changed it that much from the F4 to the F7, they like to standardise things usually to make production easier

And here's the schematic for the F4 that was taken a few pages ago, and in the top left corner is the matrix for the F4





And now I look at that matrix on the PDF, it kind of makes sense why you was hearing trim sounds on C6 hehehe

I did some tracing at the Devo F4 - but it confuses me a bit.

Traced PC9 --> Thro-V black wire
But as in the table, PB5 should lead to something - but as you see on the pictures it is not connected at the Chip
I assumed Pin1 is on the lower left corner, if the letters on the STM are rightside up - please correct me if I'm wrong

EDIT: No, i'm right. I verified it tracing PA13/PA14 to TMS/TCK

Watch the second picture for what I already traced. PC6-PC9 are clear now

Thanks, it was a bit confusing at first but now I see it. I added some info to my last post.
