For anyone interested, I managed to get telemetry working on my Quanum Nova with ArduCopter 3.2 just fine on the normal telemetry port (to which I soldered the DF13 socket). All I had to do was to compile the code myself and comment two lines in ArduCopter/system.pde (line 166 and 171):
Code:
//#if CONFIG_HAL_BOARD != HAL_BOARD_APM2 // we have a 2nd serial port for telemetry on all boards except // APM2. We actually do have one on APM2 but it isn't necessary as // a MUX is used gcs[1].setup_uart(hal.uartC, map_baudrate(g.serial1_baud), 128, 128); //#endif To save size I compiled using make on a virtual ubuntu precise32 machine (as described in http://dev.ardupilot.com/wiki/apmpil...ing_VirtualBox) and upgraded the gcc and avr-gcc packages to 4.8.2 using trusty packages (there were two libaries I had to update before that worked). I still had to disable sonar in the APM_config.h to get down to a decent size with the modification, but it works perfectly fine and connected on the first try. I found that easier than a soldering mod on board resistors. I've attached the hex file for anyone who doesn't want to compile themselves. |

I installed telemetry on my CX-20 using the resistor mod. Works well, but not something I'd recommend one do unless they have good soldering skills and are used to working around surface mount parts.
Funtastix worked his code magic with a Quanum Nova...any reason to think it won't also work on a CX-20 Open-Source? Not 100% clear whether the CX-20 OS is a 100% carbon copy of the QN from a hardware/firmware standpoint. |

A link to a (to which I soldered the D13 socket) please

I searched google etc for a D13 socket but did not find one , could you give a link to one please tks |

I've built the stable 3.2.1 branch version for the CX-20/Nova. It was actually a bit smaller, so I was able to enable sonar in that one. I will flash and try it on the weekend and report back, but it should be fine. If you have time to try it before I get to, be my guest

Thanks Don, makes sense to me now

I am new to the APM world, and have a Quanum Nova on the way and want to add telemetry. I have been wading through the forums, and have officially reached overload I presume this is going to arrive with 3.1.5, and I would really like to go the way of soldering to the telemetry pads. I am reading about all of these horror stories about upgrading to the latest firmware, and people searching for the factory firmware files to revert back. How risky is upgrading to Funtasix's 3.2.1 firmware from 3.1.5 and is recalibration the most likely hurdle?

You will have to recalibrate after upgrading to 3.2 |
