Output at Aux2 don't operate with 50 Hz

[Peter Zimmer]

I like to operate a "lost beeper" at AUX2, but AUX2 supports the servo signal with 200 Hz. The frequency has been verified with an oscilloscop. Changing the frequency of the swash blade and tail servo to 50 Hz has no effect. A SAVOX servo works well on AUX2. The "lost beeper" works well with a servo tester at 50 Hz.
I expect there is a bug in the firmware.

I use the Spirit 2
Firmware: Spirit Heli 3.3.1
Spectrum with 2 SATs
Chanel 8 is configured for output on AUX2

Hello, did you try to change the throttle frequency in the "Governor / Throttle" menu?

[Peter Zimmer]

Hello swash23,

in the throttle menu, the frequency is 60 Hz and the ESC works fine.

Regards

Peter

Hello,

I just updated to 3.3.2, changed the throttle frequency Form 60 Hz to 200 Hz, saved it to the Spirit and changed it back to 60 Hz with saving to the Spirit.
My problem that the beeper isn't working at AUX2, is still there.

I've made a interface circuit out of an Arduino Nano. Now it works.
