MPU-6050陀螺仪

低频数字式相位测量仪； 此系统由相位测量仪、数字式移相信号发生器和移相网络三部分组成。为使系统更加稳定，使系统整体精度得以保障，本电路两块T89C52为核心控制器件分别控制相位测量、数字式移相信号发生,在数字式移相信号发生部分采用了锁相技术、CPLD等技术, 使输出波形精度大大提高，并可对频率自动校验，提高频率稳定性。-low-frequency digital phase-measuring instrument; This system consists of phase-measuring instrument, digital phase shifting generator and phase three network components. To make the system more stable, the overall accuracy of the system can be protected, the two T89C52 circuit control devices at the core respectively phase measurement control, digital believe the shift occurred, the digital shift occurred some believe that the use of lock-in technologies, such as CPLD technology, the output waveform accuracy greatly improved, and can automatic calibration frequency, frequency stability.

应用背景信息存储技术进入了快速发展的阶段，信息存储技术在水声学中有着特殊的地位,水声学是需要大量收集信息的学科,以及水下条件的限制，使得对于水声学领域的信息存储技术不仅要具有较高安全性、可靠性。存储系统部分要做到功耗尽可能的低，体积更小，这样才有利于该存储系统在水下长时间可靠地工作。正是由于上述原因，选择MSP430单片作为主控器件,SD卡作为存介质。实现存储功能关键技术MSP430F5529作为主控芯片 SD卡作为存储介质 在SD卡中生成FAT32文件系统
