PWM input for RSSI

Archive
#1

The Pixhawk documentation states that the RSSI signal can be either PWM or analog (one of the reasons I upgraded from my APM2.6)

I am running 3.1.2 firmware.

I have connected the PWM RSSI output from my EZUHF receiver to Pin 103 (SBUS) but can’t figure out how to configure the Pixhawk to take the PWM signal. How do I configure this?

Thanks for your help.

The hardware is in place to do a PWM RSSI signal but the firmware to support it is not finished. Look for it in an upcoming release.

Hi Craig,
Can I assume from that, that analog RSSI code has been implemented already and that I can use the SB port for it?
Thanks,
Craig

I’ve got analog RSSI working on pin 13 (0-3.3v) with FRSKY x8r.
I haven’t tried the SB pin (Should be 103). Try it in the parameters and see if it works.
