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.

Thermometer
这是一个远程温度计
MCU: AT89S52
温度传感器: DS18B20
晶振: 12MHz
使用串口连接,在PC端使用"超级终端"打开
设置如下:
波特率: 4800
数据位: 8
奇偶校验: 无
停止位: 1
数据流控制: 无
电路图见Thermometer-SCH.jpg
该程序的编写参照了Keil UV2自带的便子
见EXAMPLESMEASURE
使用终端交互方式
其实,这不仅是一个测漫器,
它的时钟也非常准确.(This is a remote thermometer MCU: AT89S52 Temperature sensor: DS18B20 crystal: 12MHz to use serial port connection, in the PC client to use super terminal Open settings are as follows: baud rate: 4800 data bits: 8 Parity: None Stop bits: 1 Data Flow Control: No schematics see Thermometer-SCH.jpg the program prepared by the light of the Keil UV2 own son will see the use of terminal interactively EXAMPLESMEASURE In fact, this is not only a measured man, and it is also very accurate clock.)
