Pixhawk 6x rssi pin analog input does not work

ArduCopter Copter 4.4

Hello,

I try to make the rssi pin working with analog input, and this no work.
on the ardupilot wiki is marked that the rssi pin can work in analog mode.

on the ardupilot wiki about pixhawk 6X is marked that the RSSI pin is 103 as analog input:
Pixhawk 6X Flight Controller — Plane documentation (ardupilot.org)

When I check :
ardupilot/libraries/AP_HAL_ChibiOS/hwdef/Pixhawk6X/hwdef.dat at master · ArduPilot/ardupilot (github.com)

pin 103 is not defined…

Could you update asap on minor release ?

Kind regards.

I think the Pixhawk 6C has the RSSI pin implemented.
On the Pixhawk 6X diagram it’s marked as SBUS out and RSSI in - but I’m not sure how that works.

You could just use one of the ADC in pins, either 3.3v or 6.6v. If you your RSSI signal is PWM you can just use a resistor/capacitor filter to turn it into a smoother analog signal.

I already use the 2 other analog inputs…

It just need an update… Its marked, I hope this can be updated on the next minor release.

Did you try setting RSSI_TYPE to 1 ?

I want to use it as adc input… not for rssi, so I set batt2_curr pin to 103, and I get nothing…
