cw1200

TI三相电能表源程序，有很高的参考价值！(TI source three-phase energy meter, has a very high reference value!)

说明：  通过STM32的spi接口读取陀螺数据和加计数据，并对寄存器数据进行温补(Through the SPI interface of STM32, the data of gyro and add-on are read, and the data of register are compensated)

cx20106a 索尼的芯片 现已停产 不过算是非常经典的一款用于超声波接收处理的芯片，想做超声波模块的可以下载看看(cx20106a Sony chip has been discontinued, but which is a classic of a receiver for ultrasonic processing chip, the module can be downloaded want to see ultrasound)

说明：  改程序实现了用microchip公司dspic30f5015实现了PID算法。能够实现对电机的控制。(Reform program with the microchip company to achieve the realization of a PID algorithm dspic30f5015. Of motor control can be achieved.)

28335的spwm输出，开环测试，三相spwm信号分别为epwm1~6，频率为20KHz(spwm output 28335, the open-loop test, three-phase spwm signals are epwm1 ~ 6, frequency 20KHz)

说明：  对STM32单片机内部的温度进行测量，主要靠的是内部传感器(Temperature measurement in STM32 single chip computer mainly depends on internal sensors.)

用CMS16P52写的手电筒： 带摁键的，有注释(A flashlight with CMS16P52 written: with key pressed, Notes)

说明：  51单片机流水灯实验，按键按下改变流向（左移/右移）(51 Single Chip Microcomputer Pipeline Lamp Experiment, Press the Key to Change the Flow Direction)

此为51单片机的正弦波产生c程序，可将hex文件烧录到单片机内使用。(This is a 51 microcontroller sine wave generator c program, you can burn the hex file into the MCU.)

51实验21：DA数模转换 DA-PWM输出实验 * 实现现象：下载程序后DA模块上的指示灯呈呼吸灯效果，由暗变亮再由亮变暗(51 Experiments 21:DA Digital-to-Analog Conversion DA-PWM Output Experiment* Realization Phenomenon: After downloading the program, the indicator lamp on DA module shows the effect of breathing lamp, which changes from dark to light and then from light to dark.)
