No servo output on SPracing f3 evo

[Matjordan]

I cant get a tail servo to move on any of the 5 non motor outputs. it just goes to center pos and stays there. I think that servo 5 does not get mapped to a PWM output anywhere for that board.

It should be the same pin than on Cleanflight. Anyone with that board could assist?

[Matjordan]

It does not work with the cleanflight either. I did raise an issue over there too

I have similar issue but on the SPRacing F3 non-EVO, and for me it works with CleanFlight 1.14.0. With "vanilla" CF the mapping is rather odd, but it works: motor 1-3 on pin 1-3 and servo on pin 7 (instead of the usual servo on pin 1, motor 1-3 on pins 3-7 that I had on the naze) . With Triflight I had no servo out on any of the ports. Any clues?

In version 0.7b1 the resource mapping seems to be different than earlier. On my Flip32 board I had to remap motors 1-3 and servo 1-2 using the "resource" cli command. This fixed the issue for me

Please test with 0.7 Beta 2 release.

I have just flashed 0.7 Beta 2 onto my spracingf3 evo and I am not getting any servo response. Looking at the resource list I think servo one should be on port six although I did try port 5 as well and no response.

Please check this page https://github.com/lkaino/Triflight/wiki/Servo-output-channels-for-targets. The servo output for spracingf3 should be 7.

[LaraEzarik]

On that page it says its 5-8 for the EVO and not one of them works I am getting no response.

EDIT

Turns out it was tri_unarmed_servo that was set to off turned it on and the servo now works perfectly

Hello, i have flashed 0.7 Beta 2 on a SPF3 and the servo connected in the 7 pwm of the board (listed as servo 5 in the SERVO TAB as default) it works but moving in the opposite direction, i tried reversing with -100 rate but seem doesn't have any effect. Any solutions?

[dragonclips]

Im trying now to edit a normal BETAFLIGHT 3.1.7 for tricopter, just to see what happening

[LaraEzarik]

@dragonclips I suggest you open a new issue as this is an unrelated problem.

[dragonclips]

Hi, i confirm that with the BETAFLIGHT 3.1.7 all working good, i moved the servo to pin 8 istead of 7 and in the servo tab 5 all working correct.
