仪表 计量部分代码，采用ATMEL芯片，开发环境IAR(Water Meter Measurement and Display Code)

无位置传感器无刷直流电机的仿真研究，对仿真建模很有帮助(brushless dc motor)

stc12c5a60s2单片机采集心电传感器的电压信号，并在lcd12864上显示心电数字。 误差特别小。(A voltage signal STC12C5A60S2 singlechip collects the ECG sensor, and display of ECG digital in lcd12864. Especially small error.)

模拟了现实中的示波器，可以滚动显示波形，动态显示，属性振幅都可以改变 实用性 比较好 (Simulated reality oscilloscope, you can scroll waveform display, dynamic display, amplitude attribute can be changed relatively good practicality)

编写的飞思卡尔的sd卡读写程序，可以完成对sd卡的扇区读写，效率高，执行速度快(Writing the freescale sd card reading and writing program, can complete the sd card to the sector, speaking, reading and writing, high efficiency, the execution speed)

this program for student. toturial for gpio stm

FM2404铁电存储器 的历程，与AT2404有点区别，按资料上的说读写速度会比AT2404(FM2404 FRAM process, and the AT2404 a little difference, according to data read and write speed on that than the AT2404)

说明：  STM32F103实现BLDC调速，此代码可以实现BLC和PMSM开环的控制(STM32F103 realizes BLDC speed regulation. This code can realize open-loop control of BLC and PMSM.)

将设备数字量的数据采集到MCU芯片中，以既定的mqtt格式由wifi模块连接路由器传输到服务器平台。(The data of device digital quantity is collected into MCU chip and transmitted to server platform by WiFi module connecting router in established mqtt format.)

此设计模拟工业控制现场，通过调节Labview界面中的模拟仪表，通过RS232串口通信，把转速控制信息通过串口传送到单片机中，进而利用单片机控制电动机的转速。(labview-based PWM motor speed)
