"Recently with the help of one more Arduino board, i found that RC input pins are working with the same codes. Through this i came to know that it's not an software issue, it is hardware problem.
Now by anyway, is it possible to rectify where…"

Zahid Hasan replied to Zahid Hasan's discussion Ardupilot Mega RC output pins not working"Get rid of the if statement and see if you get channels values to change via the controller. Also output the APM_RC.GetState() via serial and see if you have any control over it as well."
Balaji Ranganathan replied to Zahid Hasan's discussion Ardupilot Mega RC output pins not working"Ya.. Control input and gnd i've connected to the output of Rx, since the board is powered up through USB i left the middle pin free (among the three RC pins in APM).
After adding the serial print command inside the loop, i found…"
Zahid Hasan replied to Zahid Hasan's discussion Ardupilot Mega RC output pins not working"Hey Balaji,
I am guessing you have the control input pin connected to your receiver. Put a serial output to see the state of APM_RC.GetState() and let me know what you find."
Balaji Ranganathan replied to Zahid Hasan's discussion Ardupilot Mega RC output pins not working"Hello Zahid,
I'm also facing a similar kind of problem not with the RC output pins, but with RC input pins. It was working before but suddenly it stopped…"

"Yes, that's correct. The 1.4 boards must be powered via the servo rail (a safety measure to prevent putting too much drain on the on-board power regulator). This is all in the manual, as you note."
Zahid Hasan replied to Zahid Hasan's discussion Ardupilot Mega RC output pins not working"Figured it and this is how I debugged it:
First checked it that the signal was coming through the RC output signals with an oscilliscope.
I was suprised it the signal was there, so I connected the servo signal to the rc output and the…"
Zahid Hasan posted a discussionArdupilot Mega RC output pins not working
Hello,I have an issue with the Ardupilot Mega RC output pins not working. This is a reoccurring issue on a few of my boards. I have tested one working Ardupilot Mega (older version no version number) controlling a servo, but when I transfer the code to the Ardupilot Mega (v1.4) the servo does not respond. Test code for a UBLOX GPS and serial communication to the computer were successful. I think the problem is isolated to the RC outputs. I have spent a lot of time looking through forums and…See More

Zahid Hasan commented on Howard Gordon's blog post Bat-teK video - cool highlight of some Surveyor technologies"Awesome video. I think that the misunderstanding that this is easy can be attributed to how well your finished product looks. What is the music?"
Zahid Hasan commented on Reto's blog post Adding RSSI signal monitoring for Xbees"Is there a way to access the RSSI information on the Adafruit adapter, or would I need to solder directly to my chip?"
Zahid Hasan commented on Chris Anderson's blog post How to mod a Multiplex EasyStar"Thanks guys.
I will take a look.
Best,

Thanks!"
Zahid Hasan commented on Chris Anderson's blog post Preparing ArduPilot for version 2.1 (with Z sensor)"How are both pins 4 and 5 (mux and mode) read from the CTRL pins?
Thanks"
Zahid Hasan commented on Chris Anderson's blog post FMA no longer carrying Z sensors"Thanks evilmacaw. Hmm, I will be getting my Z sensor soon. It will be interesting to see how it sends out signals to see if you can make your own."
