Dave Rigotti 3Ch proportional retro-fit

Post by drigotti »

I'm done with the conversion of a 3ch Thunder Tiger radio. All is well. I did change the pulse width to 400us BUT that is all I did. Winter has set in so I can wait a while for Phil to update the sketch for other goodies...
Thanks to all for the help!

Hi Dave, you also need to compensate by taking 100uS off every channel, otherwise your neutrals will be out. Its all caused by Spektrum's non-standard PPM timing, one of the many reasons I'm not a Spektrum fan! When I get a mo I'll separate out the PPM so you can easily set it how you like, but unforch as it stands on the 7ch its not just a case of extending the pulse to 400uS. As you know from your previous project, with the Reeduino you can!
Cheers

Phil,
Last we "talked" you were working on an update to the 7ch proportional sketch which included some neat new features. Flying season is here and would like to "update" my sketch.
Any news you can share?
The timing I have is not ideal for the Spektrum as discussed below.

Can anyone help me with the timing change as explained by Phil below? 100us off every channel? Where and how do I do this?
Thanks for the help!

static int ppm = 0, ppmPulse = 300, neutralPulse = 1200;
change to
static int ppm = 0, ppmPulse = 300, neutralPulse = 1100;
Presumably you changed the ppmPulse = 300 statement to 400?
Thanks Phil.
Yes I changed the 300 to 400. That is the only change I made,
