Nunchuck stand alone TX

Hi, guys.
I build this arduino super simple nunchuck r/c stand alone TX compatibile with futaba modules and based on Flytron's Lay-Z open source project.
I made it with an arduino nano , a case and some junk that i had at home.
It works fine with all the Futaba compatible module that I have except Spektrum. The strange thing is that module works if I use it on my 9c and I send the PPM signal by the trainer port
What do you think? Melih from Flytron says that probably depends on the channel count because spektrum module accepts only and entirely 8ch. I tried to increase it on the code without success...

Futaba transmitters in PPM mode only have 8 channels. Spectrum modules can be understood 6,7,8 and 9 channels, look in the thread http://www.rcgroups.com/forums/showt...1147689&page=4 , maybe it depends on the firmware version of the module

Thank you, Yurip. I'm thinkin too that's the problem is channel count, but nothing changes after I modify code increasing channels to 8 (lay-z send default 6ch because the 6 possible controls on the nunchuck) .
Maybe I'm doing something wrong.
I'll do more tests and report here.
