OSD joystick not working

[neistow]

While in the field, I'm trying to set up an OSD joystick to tweak camera settings. My camera is Runcam Phoenix Pro and has menu wire soldered to the CC pad on the FC (Speedy Bee F405 V3). From the docs, I don't quite understand if I can use an OSD joystick while the menu wire is soldered to the CC pad.

What I've done so far, according to the guide:

• set led_pin_pwm_mode=shared_high
• set osd_joystick_enabled=on
• Enabled Multi-color RGB LED Strip support in the configuration tab

But when trying to use stick commands to enter the camera menu, nothing happens. Moreover, when osd_joystick_enabled is ON, I can't use stick commands to get into the regular OSD menu.

Can somebody explain me how this intended to work?

Camera control is not supported in INAV AFAIK.

Hmm @RomanLut has made a number of updates to the camera control code src/main/io/osd_joystick.c and documentation docs/OSD Joystick.md

1. Which version of INAV are you using? I will double check 'when osd_joystick_enabled is ON, I can't use stick commands to get into the regular OSD menu.' - it should not happend. Also it might be the case that you entered OSD joystick mode (Throttle:CENTER Yaw:RIGHT). You have to leave OSD Joystick mode ( Throttle:CENTER Yaw:LEFT ) to be able to enter OSD CMS menu.

2. It will not work with menu wire connected directly to LED pin. You have to build RC filter as specified in the docs:
   
   Where FC_LED_PIN is connected to Flight conttrller LED pin, and OSD_JOYSTICK to camera menu pin. I would test with '''WS2811_LED_STRIP``` wire disconnected first.

3. You might need to to adjust osd_joystick_xxxx values as specified in the docs, but DOWN key should work in any case.

No, I didn't install RC Filter, because I don't have one. Is it necessary to have RC Filter in order feature to work? Just having menu wire soldered to CC pad and correct osd_joystick values is not enough? My wiring is according to this diagram:

I'm using INAV 7.1.2.

so, CC pad is the same as D4 pin?

[RomanLut]

No CC is UART? TX and is used exclusively for SmartAudio/Trump.

For OSD joystick emulation, an RC filter must be connected to the LED pin. The RC filter consists of a 470-ohm resistor and a 10µF capacitor. These components can be easily salvaged from old electronic devices.

Afaik - no? Betaflight guide to fpv camera control suggests using CC pad, so I assumed it would work in INAV too

That's an option, but at this point, for me, it's easier to plug in a harness for the OSD joystick and leave it in place, maybe zip-tie it, so it doesn't dangle around. Making an RC filter will take too much effort, which is not what I hoped for.

Could perhaps some approach similar to betaflight be implemented in INAV? I read about resource remapping and found the video why it couldn't be implemented in inav currently

Thanks for the help, this discussion can be closed.
