Serial pc (USBTX, USBRX);

int main() {
    float period, duty;
    while(1){ // 「何もしない」状態を無限に繰り返す → 上記で設定したPWM制御の状態がずっと続く
        pc.printf("Input period: ");
        pc.scanf("%d", &period);
        pc.printf("\r\n");

        pc.scanf("%d", &duty);
        pc.printf("\r\n");
        
    // specify period first
    led.period(period);      // PWM周期を4秒に設定
    led.write(duty);      // デューティー比を 50% に設定（つまり2秒点灯・2秒消灯の繰り返し）
    }
}

//pc.getc();

//限界値を設定する
//printfは重くなりやすい...??
