void main(void)
{
  // 初始化CC2530芯片和蜂鸣器
  HAL_BOARD_INIT();
  HalBuzzerInit();

  // 播放歌曲
  for (int i = 0; i < sizeof(rhythm) / sizeof(rhythm[0]); i++) {
    uint16_t freq = frequency[i];
    uint16_t dur = duration[i];
    uint16_t beats = rhythm[i];
    uint16_t pause = beats * dur * 1.5;

    HalBuzzerDelay(dur);
    HalBuzzerOff();
    HalBuzzerDelay(pause);
  }

  // 停止蜂鸣器
  HalBuzzerStop();
}

该代码使用`HalBuzzerInit()`函数初始化CC2530芯片和蜂鸣器，然后使用`HalBuzzerSet()`、`HalBuzzerOn()`和`HalBuzzerOff()`函数控制蜂鸣器发声。歌曲的节奏、频率和时长存储在`rhythm`、`frequency`和`duration`数组中，循环播放每个音符并添加适当的暂停，直到整首歌曲播放完毕。最后，使用`HalBuzzerStop()`函数停止蜂鸣器。您可以根据需要更改数组中的值来播放不同的歌曲。
