Sure. But basically, all the subjects are getting cut off.

Can you pm me a screen shot of what you mean

Gaza - can you make the subject line section in the forum topic list wider? It's cutting off the subject field really short.

ArduPPM v2.3.16 Enables FailSafe for non-FS TX/RX

Previous topic - Next topic


I';m not sure if this has been posted up here before but I';ve just successfully implemented Fail Safe on my APM 2.5 courtesy of an update of the ArduPPM controller to v2.3.16

The full read up, download and instructions are here --> http://ardupilot.com/downloads/?did=26

The documentation and download for the Link flashing tool are here --> https://code.google.com/p/ardupilot-mega/wiki/APM2Encoder

The salient points relating to the new firmware are:
Adapted behaviour in case of channel loss:

ch1, roll: set to center (1500us)
ch2, pitch: set to center (1500us)
ch3, throttle: set to low (900us)
ch4, yaw: set to center (1500us)

ch5-ch8: retain last value

In Mission Planner the default PPM value to trigger FailSafe is 975PPM and so when this new ArduPPM controller firmware loses radio signal it drops the Throttle (Ch3) PPM dow to 900 which is low enough.

I';ve not flown FailSafe (RTL) in the quad yet - but the Mission Planner indicates that it has indeed worked.
"Its better than bad, its good"

Current FCs: Pixhawk, APM 2.6, Naza M V2, Naze32, Flip32+ CC3D, KK2.1.5
Aircraft: miniMax Hex, DJI 550 (clone) TBS Disco, 450 Firefly, 250 Pro, ZMR250, Hubsan X4, Bixler 2


Just a small remark, RCTimer Arduflyer before March 2013 do not have a boot loader for the m32u2 chip so it can';t be upgraded before burning a bootloader with AVR.... burning the bootloader was a pain.
