万年历开发 时间Calendar Development - Time(Calendar Development- Time)

说明：  利用定时/计数器T0从P1.0输出周期为1s的方波，让发光二极管以1HZ闪烁，设晶振频率为12MHz(The use of timer/counter T0 from P1.0 output cycle square wave 1s, so that the light-emitting diodes 1HZ blinking, set the crystal frequency is 12MHz)

基于TI公司的msp430g2553单片机的lcd显示程序，好用(Based on TI company s msp430g2553 MCU LCD display program, absolutely easy to use)

利用ULN2003A进行驱动，产生PWM波，里边有照片，可供参考，通过本例程了解PWM 的基本原理和使用 (#include <reg52.h> unsigned char timer1 sbit PWM=P1^2 void system_Ini() { TMOD|= 0x11 //PWM TH1 = 0xfe //11.0592 TL1 = 0x33 TR1 = 1 IE =0x8A } main() { system_Ini() while(1) { if(timer1>100) timer1=0 if(timer1<30) PWM=0 else PWM=1 } )

99秒马表，在Proteus设计两个数码管动态显示及一个键盘SP。在ucos下结合keil完成开始时，显示“00”，第1次按下SP后就开始计时。 第2次按SP后，计时停止。第3次按SP后，计时归零。 (99 seconds stopwatch, two in the Proteus design dynamic digital tube display and a keyboard SP. Keil in combination ucos completed under the beginning of the show " 00" , 1st timer after pressing the SP. 2nd by SP, the time to stop. The 3rd by the SP, the time zero.)

单片机为at89s52控制步进电机正反调速实验,(The stepper motor positive and negative control experimental)

基于TI公司的msp430g2553单片机的lcd显示程序，好用(Based on TI company s msp430g2553 MCU LCD display program, absolutely easy to use)

说明：  模数转换ADC0832，基于51单片机的c语言程序(Analog to digital converter ADC0832, based on 51 MCU c language program)

将十进制数转换为二进制数和16进制数，可用于单片机初值设定时的计算(convert decimal to binary and hexadecimal ，Can be used to calculate the initial set of single chip microcomputer)
