利用Keil C51 和LabVIEW编写程序实现PC与单片机串口通信。 设计任务 PC通过串行口将数字（00 ，01 ，02，03... ，FF，十六进制）发送给单片机，单片机收到 后回传这个数字，PC接收到回传数据后显示出来，若发送的数据和接收到的数据相等，则串 行通信正确，否则有错误。启始符是数字00，结束符是数字 FF。(Use Keil C51 and LabVIEW programming to achieve PC serial communication with microcontroller. Displayed after the PC via the serial port design task digital (00, 01, 02,03 ..., FF, hex) is sent to the microcontroller, the microcontroller receives return this figure, PC receives the return data , if the data sent and received data are equal, the serial communication is correct, otherwise an error. Startup character is a number 00, the end of the character is a number FF.)

LLC型串并联谐振变换器参数分析与运用。还要我说什么的，就是这么点(LLC-type series-parallel resonant converter parameter analysis and application. What should I say, that is such a point)

说明：  pwm输出，能够实现随意改变占空比的pwm输出(PWM output, can achieve arbitrary change of duty cycle PWM output)

通用可变增益放大器，放大器的增益可设为四档：0.10―1.00，1.0―10.0，10―100，100―1000，程控DAC8043实现 ( Universal variable gain amplifier, the gain of the amplifier can be set to fourth gear: 0.10-1.00,1.0-10.0,10-100,100-1000, programmable DAC8043 implementation)

STM32采用TIM1的PWM输出，控制直流无刷电机 上传一个基本初级版的程序 PA8 PA9 PA10 PB13 PB14 PB15是PWM输出口 PC5接个电位器调节速度 PB12电源指示灯 PB5正转指示 PB2反转指示 PB0按键开机 PB1按键正反转 宏定义DEBUG可以软件仿真（DEBUG用来开启相关变量，以及变换霍尔相序）(Finally realized TIM1 PWM output, brushless DC motor control Upload a basic junior version of the program PA8 PA9 PA10 PB13 PB14 PB15 is the PWM output PC5 then adjust the speed potentiometer PB12 power indicator PB5 forward instructions PB2 reverse directions PB0 button boot Reversible buttons PB1 DEBUG macro definitions can be software emulation (DEBUG to open the related variables, as well as Hall phase transformation sequence))

此为本人在本学期单片机创新课程中做的实验之一。本实验基于nec单片机，Applilet2 for 78K0KX2和SM+编译器实现的实时可变更的PWM输出实验。虽然程序本身并不复杂，但是由于nec的源码相对稀有，相信该程序是对特定人群，尤其是和我一样也要上单片机创新课程的同学是很有帮助的。(This do for himself in this microcontroller innovation course of one of the experiment.This experiment based on the nec MCU, Applilet2 for 78 k0kx2 and SM+ compiler implementation of real-time can change the PWM output of the experiment.Although the program itself is not complicated, but as a result of the nec source is relatively rare, believe that this program is for certain people, especially as I also want to go to the single chip microcomputer innovation course of students is of great help/very helpful.)

说明：  STM32对讲机VS1053和2401。使用STM32做的对讲机，用VS1053做语音的编码和解码，用NRF24L01做通信。带有详细代码。(STM32 walkie-talkie VS1053 and 2401. Use STM32 as walkie-talkie, VS1053 as voice coding and decoding, NRF24L01 as communication. With detailed code.)

说明：  基于STM32F103和PS2遥控器的遥控小车程序(Remote control car program based on STM32F103 and PS2 remote control)

说明：  使用keil开发的基于STM32F407系的非接触式红外测温程序(Use keil developed STM32F407-based non-contact infrared temperature measurement program)

2014/3/12飞思卡尔光电组函数，线性ccd二值化成功，ccd控制舵机转角成功，直流电机成功，速度PID模块不成功，可以一战。(2014/3/12 Freescale photoelectric set of functions, linear ccd binary success, ccd control steering angle is successful, the success of the DC motor, the speed PID module fails, you can fight.)
