Arduino的草图与罗盘模块三轴磁力计HMC5883L整合。它能做什么：测量地球磁场在三个轴，具有1-2度的精度为每个轴，其可单独或一起使用的三维计算个别读数附近的磁源的措施，原强度（高斯）在三个方向上的3轴罗盘模块测量磁场 - 或轴，标记为X，Y和Z在其最简单的形式中，模块可以作为一个基本的罗盘找到地球磁北极。罗盘模块还可以感测附近的磁源，例如那些引起磁铁或电场的相对强度。作为传感器检测在三维磁性，它可以决定向这些源的相对距离和方向。

主要介绍了等精度频率测量原理，该原理具有在整个测试频段内保持高精度频率 测量的优点 同时在该原理基础上，采用了Verilog HDL语言设计了高速的等精度测频 模块，并且利用EDA开发平台QUARTUS11 3 .0对CPLD芯片进行写人，实现了计数等 主要逻辑功能 还使用C语言设计了该等精度频率计的主控程序以提高测量精度。本设 计实现了对频率变化范围较大的信号进行频率测量，能够满足高速度、高精度的测频要 求。-Introduced, such as the accuracy of frequency measurement principle, the principle has in the entire test frequency to maintain the advantages of high precision frequency measurement at the same time the basis of the principle of using the Verilog HDL language, such as the design of a high-speed precision frequency measurement module, and use of EDA Development platform QUARTUS11 3 .0 on CPLD chip to write, and achieved a count of the main logic function, such as the use of C language is also designed such precision the frequency of control procedures to enhance measurement accuracy. This design achieved a wide range of frequency changes in signal frequency measurement, to meet the high-speed, high precision frequency measurement requirements.
