说明：  stm32与fpga进行spi通信，fpga进行测频，占空比，时间间隔测量，32可控制其运行模式，并将测得结果于lcd上进行显示。(STM32 communicates with FPGA in spi. FPGA measures frequency, duty cycle and time interval. 32 can control its operation mode, and display the measured results on lcd)

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.)

LPC2119,C语言，ADS1.2,DI板电位变化，有防抖功能，测试通过(LPC2119, C language, ADS1.2, DI plate potential change, there is Anti-Shake function, test)

一个以太网帧解析程序，实现以下功能：解析已封装好的Ethernet V2.0帧封装文件（见附件），判断有多少个帧，每个帧的所有字段内容，检测CRC校验是否正确(An Ethernet frame analysis program, the following functions: parsing the encapsulated Ethernet V2.0 frame encapsulation (see annex), to determine the number of frames, each frame contents all fields to detect CRC checksum is correct)

本程序工程是编写了时钟芯片RX8025的应用代码，主要编写怎么模拟使用IIC及Rx8025的读写操作。(The engineering program is to write the application code of RX8025 clock chip, the main writing how simulation using IIC and RX8025 read and write operations.)

STM32的CAN程序，帮助学习CAN的朋友。(The STM32 CAN program to help learn CAN friend.)

说明：   51单片机的_中文拼音输入法_c源程序 拼音输入法杳询函数: unsigned char code * py_ime(unsigned char input_py_val[]) input_py_val为已输入的拼音码字符串头指针， 反回值为中文的起始地址，当为0时，杳询失败 应用举例： { unsigned char input_string[]={"bang"} unsigned char chines_string[100] sprintf(chines_string,"％s",py_ime(input_string)) }(51 Singlechip _ Chinese Pinyin input method _c source disappeared consultation Pinyin input method function: unsigned char code* py_ime (unsigned char input_py_val []) input_py_val for Pinyin input first code string pointer, and anti-back value of Chinese starting address, as 0:00, dark and quiet consultation, for example the failure of the application: (unsigned char input_string []={ bang ) unsigned char chines_string [100] sprintf (chines_string, s , py_ime (input_string))))

针对光伏电池的热板效应，主要研究当个光伏电池的电压电流I-V曲线，电压功率P-V曲线(For hot-plate photovoltaic effect, the main research when a PV cell voltage and current IV curve voltage power PV curve)

开发环境为Keil，用51单片机完成串口通讯，完成收发字符串的功能(The development environment for the Keil, with 51 single-chip microcomputer serial communication, complete transceiver string function)
