msp430g2553使用1306显示超声波测距(2553 Displays Ultrasound Ranging by 1306)

说明：  ICM20602姿态传感器在stm32上的使用(the use of ICM20602 in stm32 board)

用汇编语言写的51单片机计算器，用数码管显示，16*16矩阵键盘。计算结果可以到8位数。(Written in assembly language microcontroller 51 calculator, with digital display, 16* 16 matrix keyboard. The results can to 8 digits.)

计算器，阈值为99999999，加减乘除运算都没有问题，protues电路图 和 汇编语言都有，仿真过了，没问题。(caculator， with protues and keil software it is successed。hope it is helpful for you)

For compliance with international standards COMTRADE data format conversion, COMTRADE power system automation is commonly used data formats.

说明：  舵机转动180 直接调用已经封装号函数有dug(Direct Invocation of Steering Engine Rotation 180)

说明：  超声波定位通过头文件封装进行函数调用获得实时位置信息，方便高效。(Ultrasound positioning)

本项目是基于Cortex-M3 的地沟油快速检测装置，旨在实现“地沟油”快速，现场检测。MCU控制可编程的直接数字频率合成器（DDS）产生正弦激励信号，经过可变增益放大器（VGA）和低通滤波器（LPF）作用于食用油阻抗传感器（实验室制作）信号经过仪器放大器送入微控制器（MCU）的模数转化（ADC）通道，MCU对采集的信号通过快速傅里叶变换（DFT）处理，实现食用油阻抗与相角的检测；USB和以太网接口，可与计算机通讯，以便对采集的数据进行存储和分析。(The project is based on the Cortex-M3 waste oil rapid detection device designed to achieve " waste oil" rapid, on-site testing. MCU control programmable direct digital frequency synthesizer (DDS) generates sinusoidal excitation signal through a variable gain amplifier (VGA) and a low-pass filter (LPF) acting on the oil-impedance sensor (lab produced) to send signals through the instrumentation amplifier into the microcontroller (MCU) modulo conversion (ADC) channels, MCU signal acquisition via Fast Fourier Transform (DFT) processing, oil resistance and phase angle detection USB and Ethernet interfaces, and computer communication, in order to collect data for storage and analysis.)
