i can bind with x4, so i think my problem is with ppm on dsc port(trainer)

Remove the resistor going to ground in the divider (leave only the one in serial) then it should work, that's because PPM output level is 3.3V on Spektrum radios, if you use a 1/2 voltage divider, only 1.65V goes to the AVR, which is not enough to pull the input HIGH.

You may have to set endpoints too.

Hi Midelic,
I have a problem with your Recepter. I tested your 5 programs and none on work. I can't bind except for the "Hubsan_RX_ppm_M328_16Mhz" where ppm does not. Furthermore the ppm is inversed.
Would it be possible to have the sources to correct and test directly.
