Hi There, I am an Arduino beginner having a tough time porting a serial command from ArduCopter 2x to the new ArduCopter 3x. I am trying to send serial data out on pins 16 and 17 of my ArduPilot Mega APM2.

Any help would be greatly appreciated! In ArduCopter 2x I was able to add a FastSerialPort2(Serial2) in ArduCopter.ino then do the following in my UserCode.ino file:

void userhook_init()
{
// setup serial port
Serial2.begin(9600);
}

void userhook_50Hz()
{
// Begin sending out data
Serial2.print("DATA: ");
Serial2.print(current_loc.lat);
Serial2.print(" ");
Serial2.print(current_loc.lng);
Serial2.print(" ");
Serial2.print(ahrs.roll_sensor);
Serial2.print(" ");
Serial2.print(ahrs.pitch_sensor);
Serial2.print(" ");
Serial2.print(ahrs.yaw_sensor);
Serial2.print("\n");

}

But I'm not sure how sending serial data works in the new version, as no FastSerialPorts are defined. Any pointers on how I may get that above code to work in the new UserCode.ino, which is:

#ifdef USERHOOK_INIT
void userhook_init()
{

// put your initialisation code here
// this will be called once at start-up

}
#endif

#ifdef USERHOOK_FASTLOOP
void userhook_FastLoop()
{
// put your 100Hz code here
}
#endif

#ifdef USERHOOK_50HZLOOP
void userhook_50Hz()
{
// put your 50Hz code here
}
#endif

#ifdef USERHOOK_MEDIUMLOOP
void userhook_MediumLoop()
{

// put your 10Hz code here
}
#endif

#ifdef USERHOOK_SLOWLOOP
void userhook_SlowLoop()
{
// put your 3.3Hz code here
}
#endif

#ifdef USERHOOK_SUPERSLOWLOOP
void userhook_SuperSlowLoop()
{
// put your 1Hz code here
}
#endif

Any help or pointers would be greatly appreciated. Thank you. -John
