PPM encoder firmware

Posted by David Ardis on April 21, 2013 at 1:53pm

I have a APM Ver 1 which I recently installed into a 3DR Hex frame. I have a problem getting channel 6 to work. When I calibrate the radio channel 6 does not work if I unplug ch6 from the receiver and plug it in again it works until the radio is switched off.

If I update the PPM encoder firmware will it solve this problem

I am using a futaba14mz and 7channel 2.4 Ghz receiver

Thanks

    Is there someplace in the Arducopter code or whatever code is using the PPM signal where you can set the # of channels to 1 greater than you actually have?  If your encoder is connected to 6 channels, then set the code that reads the encoder output to 7. 

    It's a shot in the dark, but I had a similar problem with an encoder.  Different firmware, different encoder, but the code that read the PPM output needed to be set to 7(6 + 1) before it would read it.
