正弦波电流驱动的无刷直流电机性能分析，通过分析方波电流驱动与正弦波电流比较，得出正弦波电流驱动电机性能较好(Sine wave current drive brushless DC motor performance analysis, by analyzing the square-wave current drive with sine wave current comparison, the sine-wave current drive motor performance is better)

说明：  In the data management system a significant role of the Data link layer is to convert the unreliable physical link between reader and tag into a reliable link. Therefore, the RFID system employs the Cyclic Redundancy Check (CRC) as an error detection scheme. In addition for reader to communicate with the multiple tags, an anti-collision technique is required. The technique is to coordinate the communication between the reader and the tags. The common deterministic anti-collision techniques are based on the Tree algorithm such as the Binary Tree and the Query Tree algorithms.

具体设计内容计时功能：电子表的基本功能，要求用LCD显示，显示格式是时、分、秒；校时功能：用户可以更改当前时间。设置闹钟时间：用户可以设置闹钟时间，其操作过程与校时过程一样；整点报时开关：整点报时可以由用户设定为开启或关闭两种状态，当整点报时开启时，电子表会在整点时发出1秒的闹铃声（在UP3的板上用一个LED表示）；闹钟功能开关：闹钟由用户设定为开启或关闭，当闹钟开关开启时，如果当前时间与设置的闹钟时间一致，发出长达10秒的闹铃声；

veilog 代码 用户可以直接调用，作为底层模块。同时已经编译成功，可以作为基本单元库。-veilog code user can derict use it for the base mode.
