PPMSim output PPM-Signal Error??

[Helle]

Hy,

I have flashed the latest open9x, relesase r1195, and cheked the output signal at the 3,5mm DSC-Jacket with an Oszi

When I set PPM to Positv (+) a negativ PPM-Signal comes out
When I set PPM to Negativ( -) a positiv PPM-Signal comes out

I think this is not korrekt, could anyone test it again.

I know there is a difference in Europe with the Standard PPM-Signal and in the States with positiv and negative Shift-Signal

Looks good to me. Positive = idle low, pulses high ("positive", active edges are rising edges). Negative = idle high, pulses low ("negative", actve edges are falling edges).

hy,

yes, the Signals are ok, but the setup at the open9x softwere is wrong!

see Modell setup Page Setup 01 2/11
...
.....
22,5ms 300u + for Positiv , but negativ Signal comes out, idle high level, pules low
22,5ms 300u - for Negativ, but positiv Signal comes out, idle low level, pulses high

Thats what I see at the Oszi

Ah, OK!

Then yes, I can confirm! + and - are swapped for all PPM settings.

[Kilrah]

There, + and - display swapped on svn.

Hy,

This is at the DSC 3,5mm Jacket output für FlightSim with PPMsim and for student output PPM and PPM16, all the same.
I checked it because I got problems with a USB-Simulator Cable, doesn´t work.

Now,
please could onyone test it again and
how can we change it in the next release of Open9x

Yes I checked, it was wrong also on the module connector. I swapped +/- display in the code, it will be in next release.

Hy,

thanks!
