led-clock
The LED clock consists of 60 LEDs which are placed circular around a common analog clock. The LEDs are used to display the seconds. Essential part of this circuit is the LED driver MAX7219 from Maxim. A datasheet is available on Maxim s homepage. The clock is controlled by the microcontroller AT89C2051 from Atmel. This microcontroller is clocked at a frequency of 12 MHz from which results a time base of 1 microsecond. Via software dividers one clock impulse per second is generated which is used for updating the LED display.

一个倒车雷达的程序
使用的是AVR单片机。
在include.h文件里面定义
#define CPU_F 4 //4MHZ 定义外晶振的频率
#define GOOD //40KHZ更准确
#define DIS150CM //若定义了,1.5M有效,没有定义就是2.5M有效
#define DEBUG //若定义了,则是调试模式debug , 没定义就是release模式
(Include.h document in which the definition of# define CPU_F 4// 4MHZ definition of the frequency of oscillator# define GOOD// 40KHZ more accurate# define DIS150CM// if defined, 1.5M effective, efficient 2.5M is not defined# define DEBUG// If defined, it is debug mode debug, not release model is defined as)
