I am trying to get this board going with a FrSky v8r7sp which has PPM. I know the board is working because I hooked it up to a regular JR RX and everything works great. GUI tells me it all is working. When I hook up the FrSky with the one lead from the PPM out (ch8) to the board, it doesn't see it. I also see in the the WIKI of MultiWiiCopter it says "Dont forget to enable the Sketch Code for PPM sum" but that is all it says. How do I go about doing this? Am I missing something? Any help would be great.

You need to look in config.h and uncomment PPM_SUM or similar define, and choose your channel order.

/* The following lines apply only for specific receiver with only one PPM sum signal, on digital PIN 2
   IF YOUR RECEIVER IS NOT CONCERNED, DON'T UNCOMMENT ANYTHING. Note this is mandatory for a Y6 setup on a promini
   Select the right line depending on your radio brand. Feel free to modify the order in your PPM order is different */
//#define SERIAL_SUM_PPM         PITCH,YAW,THROTTLE,ROLL,AUX1,AUX2,CAMPITCH,CAMROLL //For Graupner/Spektrum
//#define SERIAL_SUM_PPM         ROLL,PITCH,THROTTLE,YAW,AUX1,AUX2,CAMPITCH,CAMROLL //For Robe/Hitec/Futaba
//#define SERIAL_SUM_PPM         PITCH,ROLL,THROTTLE,YAW,AUX1,AUX2,CAMPITCH,CAMROLL //For some Hitec/Sanwa/Others

OK I will try that. I'm new to all this. Thanks.
