Move servo from S1 to S6 pin for MATEKF405

[alexeystn]

When SERVO_TILT is enabled, servo signal goes to S1 output. Motor 1 stops working therefore.
Now servo can be attached to S6 output of MatekF405:
feature SERVO_TILT
servo 0 1000 2000 1500 100 8

#2644

Please don't break my existing tri-copters. We've been through this before.
#2566

[alexeystn]

Oh, sorry.
So, what's the solution? Is there a chance to keep motors at S1..S4 and servo at S6 for quads and don't break tri-copters?

[stronnag]

It would have to be another target. I agree this is really inconvenient one way or the other. The way the MATEKF405_OSD is a "fork" of the MATEKF405 target.

[alexeystn]

Thank you, now I understood.
Do you have F405-OSD on your tri-copters? That one with through-hole S1..S4 pads and difficult-to-solder S5..S6, right?
I guess, another target for my F405-CTR is the only way out.

[stronnag]

I have MATEK-OSD on one, and MATEK-STD on the other.
You are correct, having assembled the board with S1-S4 pins / through-holes, retro-fitting S5 would be quite difficult, at least for my soldering ability.

[alexeystn]

All right, let's think about how these targets can be separated.
There are 4 boards in Matek F405 family: OSD, STD, AIO, CTR.

1. Boards OSD and STD have through-hole pads for S1...S4.
2. Boards AIO and CTR have surface pads for all S1...S6 channels. No difference, but S1..S4 are good for quad motors, because they are located in the corners, and S5 or S6 is perfect for camera-tilt servo.
3. OSD has software I2C.

The question is: do we need to create separate targets for all of these boards?

[alexeystn]

Another option is to create MATEKF405_SERVOS5 or MATEKF405_SERVOS1 target.
I don't know if producing so many targets for each particular case is a good practice. But I can't see any other way to satisfy both quad and tri-copter users.

[stronnag]

This is not a particularly helpful target name, as it may confuse tricopter users with a MATEKF405-STD board. Perhaps MATEKF405FW would be an alternative?

[alexeystn]

I can explain, It's not for fixedwing, it's for quadcopter users like me, who need S1..S4 for motors and S5 or S6 for camera-tilt servo.

[stronnag]

OK, but it's still confusing to name it for a particular FC when it's a servo configuration setting across multiple FCs (F405, F405CTR, F405STD).

[stronnag]

And however the variant is named, the Boards documentation file will need to be updated, to avoid further user confusion.

[alexeystn]

Ok, I agree. Thank you for reminding me of documentation.
I tried to find a solution, where servo can be easily remapped from S1 to S6 in configurator, depending on aircraft type (tri/quad). But it requires serious changes in code.
So I believe, the easiest solution is MATEKF405_SERVOS6 target. What do you think?

[stronnag]

We have a winner! In fact, I think your solution is the correct one, and the initial setup was a mistake (with the benefit of hindsight, of course).

In a perfect world, we would rename the original target to MATEKF405_LEGACY and call your solution MATEKF405, but that might just be too confusing (even if it's my preferred outcome).

[digitalentity]

Let's create a SERVOS6 target and see some usage statistics. Then we could make a decision renaming them

[stronnag]

merging per @digitalentity's advice

[markandkymward]

Thank you for your work @alexeystn. I believe that this is exactly what I am looking for. I've posted a comment on RCGROUPS that explains some problems I'm having. Here is the text -

Subject flight controller with S6 pad connected to tilt servo, running development (@alexeystn ) MKF4 firmware dtd Apr 6. SERVO_TILT feature is active. In INAV servo tab I can successfully attach the servo0 to a flight control output but am unable to get a servo mix that will add stabilized pitch. Also, changing rates to negative does not appear to change servo direction.
Here's the dump:
