As I am not getting an answer here, I seem to have to work based on the files that are provided. You can find all the hardware and software changes here: https://github.com/esden/ppm_to_spektrum_encoder

 

Still work in progress... :)

this isn't very encouraging!

I just bought the V2 PPM encoder, and the files and manual for it are wrong!

Anyone know where the correct documents are?

The eagle schematic and pcb files in the listing are correct for the board that ships from 3dr.

The 3dr variant uses the Paparazzi firmware so the functionality of the 3dr board is identical to the Paparazzi board but the wiring and layout shown in the Paparazzi manual do not.  That's where the confusion comes from.

There was never a 3dr variant of the manual produced so we only have the wording and images from the original authors.  The source code is in the product listing though so I suggest referencing it to help understand the behavior of the encoder.
