巧用C8051F410的PCA实现超声波测距(Using the PCA to achieve ultrasonic ranging C8051F410)

由单片机和DAC0832产生正弦波或三角波的程序。单片机和DAC0832可将频率进行分频的具体程序(Sine or triangle wave and DAC0832 procedures generated by the microcontroller. SCM and DAC0832 can divide the frequency of specific procedures)

说明：  改程序可简单的产生从0到f的递增数码管显示，着为初学者提供比较好的认识。(Reform program can generate a simple increments from 0 to f, digital tube display, forward to providing a better understanding of beginners.)

定时器中断试验的程序源码，经试验调试已完全调试通可以使用(Timer interrupt testing procedures, debugging has been fully debugged by the test can be used through)

里面含有2015年全国大学生电子竞赛的简易频谱分析仪的全部程序，基于STM32的ADF4351以及AD8310对数检波原理图(includeing based on STM32 sADF4351andAD8310)

基于51单片机的计算器 ，采用C语言编写，可以实现简单的加减乘除功能，用八位数码显示。(counter based on as89s51)

自己写的C51开发板上硬件驱动，可作为工程开发模板，芯片是stc12c5060s2 上传项目是数字语音存储与回放(C51 development board hardware drivers to write their own, as the engineering development of a template, the chip is stc12c5060s2 upload project digital voice storage and playback)

交通信号灯控制，可以调红绿黄灯时间，有紧急模式和夜间模式( Traffic lights control, you can adjust the red and yellow light time, emergency mode and night mode)

说明：  基于stm32单片机做的无刷直流电机的矢量控制(Vector Control of Brushless DC Motor Based on Stm32 Single Chip Microcomputer)
