PIC Microcontroller project Door lock with PIC16f84a

最小的单片机PWM控制，电压控制PWM输出，智能化，体积小。(ADC control PWM output)

单片机串口通讯测试源码，适用于点对点通讯！(Serial Communication test source for point to point communication!)

1. 本研究利用 PCA 对可见-近红外（450～1 000 nm）、可见光（450～780 nm）和近红外（780～1 000 nm）光谱区域的苹果高光谱图像数据进行降维，获得 PC 图像，通过对 PC 图像进行分析，确定可用于分割损伤和正常区域的有效光谱区域，对比分析几个光谱区域的 PCA 的效果。(but currently no practical system for detecting blood spots and dirt stains exists. In order to obtain maximum throughput, processing speeds of over 85,000 eggs per hour are common. The demanding requirements placed on the human workers result in two types of grading errors)

while(1) {//if(keyenable==1){P1=0x00 P2=0xff }else{P1=0xff P2=0x00 } for(i=3 i<SNAKE+1 i++)x[i]=100 for(i=3 i<SNAKE+1 i++)y[i]=100 //初始化 x[0]=4 y[0]=4 //果子 n=3 //蛇长 n=-1 x[1]=1 y[1]=0 //蛇头 x[2]=0 y[2]=0 //蛇尾1 addx=0 addy=0 //位移偏移 //k=1 while(1){if(keyenable)break timer0(1) } while(1) {timer0(e) if(knock()){e=SPEED break } //判断碰撞 if((x[0]==x[1]+addx)&(y[0]==y[1]+addy)) //是否吃东西

高精度算法的，PT100测温项目，包含源代码和设计文档，还有原理图(High precision algorithm, PT100 temperature measurement project, including source code and design documents, as well as schematics.)

60秒倒计时显，两位数码管实现，倒计时，通过中断实现，含仿真图程序(60 seconds countdown display)

新手适用黑线寻迹代码，适用于arduino开发板(Novice is suitable for black line tracing code and Arduino development board)

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)

采用MSP430G2553和12864液晶实现控制界面，可控制端口输出不同频率的脉冲波形，同时还可测量不同信号的电压值(12864 achieved using MSP430G2553 and control interface, you can control the port output pulse waveforms of different frequencies, but can also measure the voltage values ​ ​ of different signals)
