The USB Radio Dongle acts as the bridge between the Client and the Firmware. It sends control setpoints generated from the Client to the Firmware controllers, as well as receives sensor data from the Firmware to the Client for logging.


Modifying the Radio

The Radio functions can be found in the CCrazyRadio.cpp source file.

Radio Initialization

1. Create CrazyRadio Pointers and Crazyflie Pointers

CCrazyRadio *crRadio1 = 0;
CCrazyRadio *crRadio2 = 0;

CCrazyflie *cflieCopter1 = 0;
CCrazyflie *cflieCopter2 = 0;
CCrazyflie *cflieCopter3 = 0;
CCrazyflie *cflieCopter4 = 0;

Note: You must have a pointer for EACH Radio you want to initialize.

2. Initialize First CrazyRadio

crRadio1 = new CCrazyRadio(0); // dongle number (starting at 0)
if( crRadio1->startRadio() ) //assigns pointer to USB location
{
cflieCopter1 = new CCrazyflie(crRadio1, 5); //Assigns Crazyflie1 to Radio1 on Channel 5
cflieCopter2 = new CCrazyflie(crRadio1, 80); //Assigns Crazyflie2 to Radio1 on Channel 80
}
else
{
std::cerr << "Could not connect to dongle 1. Did you plug it in?" << std::endl;
exit(-1);
}
usleep(10000);

3. Initialize Second CrazyRadio (repeat as necessary...)

crRadio2 = new CCrazyRadio(1); // dongle number

if( crRadio2->startRadio() )
{
cflieCopter3 = new CCrazyflie(crRadio2, 25);
cflieCopter4 = new CCrazyflie(crRadio2, 45);
}
else
{
std::cerr << "Could not connect to dongle 2. Did you plug it in?" << std::endl;
exit(-1);
}

usleep(10000);
