摘 要 电机转速是电机的一个极为重要的状态参数 文中介绍了几种基本的电机转速测量 方法 并对这些测量方法进行了比较 给出了基于加速度计进行电机转速测量的硬件电路设 计方法和测试系统的工作原理(Summary of the motor speed is an extremely important motor state parameters paper describes several basic motor speed measurement methods and these measurements were compared based on accelerometer gives the motor speed measurement hardware circuit design and test systems Works)

基于DSP2812对于挂在一条总线上多个18B20采集温度的程序，通过读取每个18B20不同的64位编码，发送数据匹配编码来确定某个18B20，可以读取温度(Based on DSP2812 hanging on a bus for more than 18B20 temperature acquisition program by reading each 18B20 different 64-bit encoded transmission data to determine a match-coding 18B20, you can read the temperature)

说明：  ASCII码字库，包括12*12，24*24，32*32(ASCII codeword library, including 12*12, 24*24, 32*32)

This project of digital thermostat is made in asm.

说明：  使用单片机利用超声波测距，里面包括源代码(Using Single Chip Microcomputer to Measure Distance by Ultrasound)

说明：  该工程是基于LPC1857单片机开发的数控程序，包含了SDRAM、EMMC驱动代码，还在单片机上移植了UCOSIII系统，并在此基础上移植了FATFS文件系统、LWIP1.4.1网络协议栈。该工程是实际项目中的源码，稳定性绝对有保障，供大家参考。(The project is based on LPC1857 microcontroller development of CNC program, including SDRAM and EMMC driver code, and also transplanted UCOSIII system on MCU. On this basis, FATFS file system and LWIP1.4.1 network protocol stack were transplanted. The project is the source of the actual project, the stability is absolutely guaranteed for everyone's reference.)

This program operate mathematic functions on numbers
