说明：  四位共阴数码管显示实验（段选＋位选）代码 适用于STM32F103单片机(Four common negative digital display experiment (segment selection + bit selection) Suitable for STM32F103 MCU)

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.

最近几天突然对红外线遥控器发生兴趣，于是上网混了一下，发现编码方式有好几种，而且同一种编码方式又有许多不同的细节，为了弄清楚手头的遥控器是出身何门，无奈手头又没有logic分析器之类可望不可及（广东话里“及”同“望”都系“睇”既意思）的东西，遂萌生了写这个软件的冲动。(Infrared logic analyzer )
