Combined PPM (CPPM) Receiver Library for Arduino

This library provides a simple interface for reading up to 16 channels of RC input from a single CPPM signal:

void setup(void)
{
    CPPM.begin(NUM_CHANNELS);
}

void loop(void)
{
    int16_t channels[NUM_CHANNELS];

    if (CPPM.ok())
    {
        CPPM.read(channels);

        // do something fun with the channel values, like fly a quadcopter...
    }
}

In its current form, it most likely only works on Arduino Uno. It requires exclusive access to timer1, preventing the use of PWM on digital output pins 9 & 10 (whose waveform generator also use timer1).
