[单片机开发] mega16clock

当时钟正常走的的时候,按一下key2,第一位开始闪亮,且通过key1来对该位进行加1操作,通过key2来向右移动要调节的位的闪亮和通过key1进行加操作完成校时功能,知道按到数码管不再闪亮
When the clock normal walking, click the key2, first begin to flash, and by key1 to this bit are incremented by key2 to move to the right to adjust the bit shiny and add operation performed by key1 complete timing function, press to know that digital is no longer shining (2016-07-18, Others, 8KB, 下载1次)

[单片机开发] clock

clk: 标准时钟信号,本例中,其频率为4Hz; clk_1k: 产生闹铃音、报时音的时钟信号,本例中其频率为1024Hz; mode: 功能控制信号;为0:计时功能; 为1:闹钟功能; 为2:手动校时功能; turn: 接按键,在手动校时功能时,选择是调整小时,还是分钟; 若长时间按住该键,还可使秒信号清零,用于精确调时; change: 接按键,手动调整时,每按一次,计数器加1; 如果长按,则连续快速加1,用于快速调时和定时; hour,min,sec :此三信号分别输出并显示时、分、秒信号, 皆采用BCD码计数,分别驱动6个数码管显示时间; alert: 输出到扬声器的信号,用于产生闹铃音和报时音; 闹铃音为持续20秒的急促的"嘀嘀嘀"音,若按住"change"键, 则可屏蔽该音;整点报时音为"嘀嘀嘀嘀-嘟"四短一长音; LD_alert: 接发光二极管,指示是否设置了闹钟功能; LD_hour: 接发光二极管,指示当前调整的是小时信号; LD_min: 接发光二极管,指示当前调整的是分钟信号。
If long press, the continuous rapid plus 1 for quick adjustment and timing, Hour-by-hour, min, SEC: this three signal output and display when respectively, minutes and seconds signal, All USES BCD counter, respectively driven six digital pipe display time, Where the signal to the speaker: output, used to produce make primitive and strike the sound, Make businessis about for lasts 20 seconds the urgent "di di di" sound, if hold "information" key, Then can shield the sound, Integral point to announce the sound as "di di di di- du" four short a drawl, LD_alert: connect the light emitting diode, instruction set the alarm clock function whether LD_hour: connect the light emitting diode, instructions, the current is to adjust the hour signal, LD_min: connect the light emitting diode, instructions, the current is to adjust the minutes signal.
