keil C51 Safter－Switch事例

基于51单片机的多功能数字钟。时间，年月日，多组闹钟，议程。且外接24C04的EEPROM后可保存设置。蜂鸣器由I/O口接三极管放大后驱动。-51 microcontroller-based multifunctional digital clock. Time, date, multiple alarm clocks, and the agenda. 24 C04 and external EEPROM kept after setting up. The buzzer sounded by the I/O access triode mouth amplified drive.

设计分为5 个模块：前轮PWM 驱动电路、后轮PWM 驱动电路、轨迹探测 模块、障碍物探测模块、光源探测模块。前轮PWM 驱动电路用于转向控制；后 轮PWM 驱动电路用于方向和速度控制；-Design is divided into five modules: front-wheel drive PWM circuit, rear-wheel drive PWM circuit, the track detection module, obstacle detection module, detecting the light source module. PWM drive circuit for front-wheel steering control rear-wheel drive circuit for PWM direction and speed control

51的4*4键盘驱动当按键按下时返回一个值，且只在按下键时返回一次该值，之后返回0；无按键时返回0；包含消抖功能，在键盘的下降沿触发。 基于keil平台-51 4* 4 keyboard driver when the button is depressed to return a value, and press the button only once the value to return, followed by return 0 no keys to return 0 contains extinction Buffeting function, the falling edge trigger at the keyboard. Keil-based platform

点阵液晶取模取模软件，里面可以设置很多种方式，纵向取模与横向取模等可以适应各种LCD-Modulus modulus matrix LCD software, which can be set to very many ways, vertical and horizontal modulus modulus, etc., may adapt to a variety of LCD

32位 RFID 开发板,支持多种13.56M卡.-32 RFID development board to support a variety of 13.56M card.

* 功能：使用PWM6输出PWM信号，通过滤波电实现DAC转换。由KEY1控制PWM的占空比， * 每按一次按键将会改变一次PWM的占空比。 * 说明：使用示波器观察测试点PWM和PWMDAC。-* Function: Use PWM6 output PWM signal, by filtering electrical realize DAC conversion. Key1 controlled by the PWM duty cycle,* every time a button will change the PWM duty cycle.* Note: Use the oscilloscope to observe test points PWM and PWMDAC.
