Gents I need your help.
I recently upgraded one of my 2.6APM powered quads to a Pixhawk. One of the reasons I went ahead and did this is because the Pixhawk is supposed to take PWM RSSI signals directly (into the Sbus port aka Pin 103) and I could ditch my PWM to analog conversion circuit is used in my APM.
I have verified that my EZUHF receiver is outputting RSSI in PWM form on one of the channels. (it will move a servo appropriately when the RF gets weak or disappears... and it worked fine for the APM as an RSSI input via a PWM to analog conversion circuit)
And, I have hooked up the PWM RSSI output to the Sbus port (pin 103).... it does nothing. Shows zero RSSI on the OSD no matter what.
I can't find any useful description of how to configure this in the wiki, mission planner or this site.
How do you make a Pixhawk show RSSI from a PWM input on pin 103 as its advertised?
Thanks for your help.
Steve!!! Thanks a lot Man!!
So, I was able to bind, but I did had to update firmware on my TX up to 1.50...
I just run a small test and pixhawk its reading ezuhf now :)
I didn't wanted to get back to u unless I had tried it... I really appreciate your help!
Got the EZUHF RSSI/Link to work with my Skywalker APM 2.6 plane.
The RSSI has inverted values and extra percent sign problem but it works!
What I used:
EZUHF TX/RX firmware v1.50
ImmersionRC Config Tool v1.40
MinimOSD firmware Extra Plane v2.4 Pre-Release r719
Config Tool for MinimOSD v2.4 Pre-Release r727
No settings needed to be changed in the APM Mission Planner
RSSI MIN/MAX 993/1650
Link Quality MIN/MAX 1074/1794
Here is a tutorial video I made for the EZUHF RSSI / Link Quality with APM 2.6 or Pixhawk
You have done nothing wrong.
Unfortunately the RSSI is inverted with the EZUHF.
In the movie you will see that I chose to use Link Quality which is non-inverted and responds to degradation from interfering signals. In my opinion Link Quality is the better choice anyway.
trying to set this up and I find when I assign EZUHF LQ to channel 8 I lose my flight mode selection
Using the latest APM plane on an APM 2.6
Any clues Gents, this is driving me spare!
I moved my flight modes to a different channel.
Look a about time code 2:17 in this video for the schematic and explanation:
I have watched your Video a couple of times, very well presented
I am using CPPM and want to keep it that way
My problem is I cannot figure how to switch my Flight mode select channel to anything other than Channel 8 (I'm using Arduplane 3.2)
I note in your schematic you use channel 6, how did you change that from what appears to be the default of channel 8
To confuse the issue more the current setup wiki says to use channel 5 which doesn't work for me
I changed the flight mode channel input from the default 8 to 6 in the mission planner and then wrote the settings to the APM.
Please forgive my stupidity but I am asking how to do that
What parameter are you changing and where do I find it?
