数码管显示数码0-9字母AbCdEFHJLoPUy些本显示数码所才叫数码管并能显示全部26字母用液晶屏1602解决简单

七段数码管不一定能够清楚显示所有的英文字母,如m就不能显示,虽然说七段数码管能够显示128个字符,但是有些是很简单的字符,除非是点阵才能够显示所有的字符,---前提是要软件.

回答和翻译如下：LCD 段码液晶LCD Segment LCD

大家平常在生活之中见到最多的可能就是段码液晶屏了，它有着普通数码管的特征，又有着点阵液晶屏的特征，已经固定的图形，既省成本而且又好看，那么，我们今天来一起试一试！首先，大家都不要以为使用单片机来驱动，就以为是断码屏直流驱动的了，其实呢，段码屏它是交流驱动的，什么是交流驱动呢？例如矩形波、正弦波等等。大家可能会经常的使用驱动芯片来玩，例如ht1621等等，但是有一些段式屏的io口是比较少的，或者说是io口充足的情况之下，也懒得在再去写控制器的驱动了。但是，io的模拟驱动，段式液晶是有一个前提条件的，就是io必须要是三态，为什么？下面我们就一起细细的道来：第一步：段码液晶屏最重要的参数：占空比、工作电压、偏压比。这三个参数都是非常重要的，都必须要满足。第二步：驱动的方式：我们根据 lcd 的驱动原理可以知道，lcd的像素点上面只能够加上 ac的电压，lcd显示器的对比度则是由 com脚上的电压值减去 seg 脚上的电压值来决定，当这个电压差在大于 lcd 饱和电压时就能够打开像素点，小于 lcd 阈值电压时就能关闭像素点了，lcd 型的mcu 已经由内建的 lcd 驱动电路自动产生出lcd驱动信号了，因此只需要 i/o 口能仿真输出该驱动的信号，就能够完成 lcd 的驱动了。段码液晶屏主要是有两种引脚，com和seg，和数码管比较像，但是，压差必须要是交替变化的，例：第一时刻是正向的3v，那么第二时刻就必须要是反向的3v，注意一点，如果你给段码液晶屏通直流电，那么不用多久这个屏幕就会报废，所以千万要注意。下面我们就来考虑如何模拟com口的波形，我们以1/4d，1/2b为例子：段码lcd屏的驱动方法只要模拟出以上的波形，你的液晶屏就已经成功了一大半。void display_sub(u8 y) //lcd display subroutineswitch(y) //4*com,vdd and -vdd lcd display,so 8 timebase interrupt one sacn periodcase 1:case 2:case 3:case 4:case 5:case 6:case 7:case 8:default:get_display_code(ad_value,keyscanretval);break;}}}复制代码如上图代码所示，定时到2ms，让4个com交替的输出波形就可以了。文章转载于lcd液晶屏：http://www.hzjingxian.com，转载请注明出处同时我们还要注意，在com的输出较高的时候，如果要屏幕亮，那么seg就要输出低，那么在com输出低的时候，seg就要输出高了，保证com和seg的压差大于1/2b工作电压就可以正常显示了下面我们看其中一个com口输出时的函数static void seg1_output(void) //seg1 output subroutineif(1 == (lcdplusestep%2)) //com_pulse is odd,com output high (vdd)if(0 == (displaycode1&0x10))else}else //com_pulse is even,com output low (vss)if(0 == (displaycode1&0x10))else}}复制代码必须时刻让seg电平跟com的电平成反向，那么驱动段式液晶就不会有多大的难度了段码液晶屏：http://www.hzjingxian.com文章原创于http://www.hzjingxian.com/zixun/xydt/822.html，转载请注明出处

4，HuMoR英文什么意思

western humoreverybody knows that occidentals are very humorous. in the beginning, i dont quite catch that. but recently, i feel the humorous way of occidental deeply. one day when we had class of foreign english teacher. in order to see how well we could write in english, he wrote a topic on the blackboard and let us to write an article in english. the topic was very simple, just talked about the thing of our university or the thing which happened around us. it is either complimentary or critical. our students were very clever. we finished the article quickly and gave it to the teacher. he read the articles carefully and then picked one which he thought was the best. when he read it out to us, we were very confused. why it was the best article, not a single word of it was true.the article described our cafeteria and the author was a peaceable student from a village in the outskirts. he was timid, so in order to not offend the institute authorities---the decisive factor concerning his final grading, evaluation and where he was to go after graduation ---he had made up a high –sounding story in praise of the cafeteria, regardless of the realities. we were all very angry about what he did. but, the teacher was aware of the cafeterias terrible conditions, why did he have his eye on this one in particular? we couldnt help ourselves asking him why. our teacher explained “this is certainly a good article. absolutely matchless! listen …” he picked up the article and read it loudly. “the most beautiful place in our university is not the classroom, nor the sport-ground, nor the lawn with the fountain at the gate; the most beautiful place in our university is our cafeteria. look, the windows are so clean that you scarcely notice there is glass in them …” and then he paused, his eyes flashing with a glint of wits and his brows shooting upward. “listen, how humorous it is!”humorous? why it was humorous? the students were still confused and let him read it went on. the teacher continued, “if you were not careful enough and had a fall on the floor, you would be amazed to find that you had not fallen at all because you did not get a particle of dust on your clothes. if you had been working in the cafeteria for a long time, you would have forgotten what a fly looks like…” he stopped again, his tongue clicking rapidly to show admiration and made a face. “listen. do you think anyone else couldve made it more humorous? if laughed so heartily that i could hardly continue.” he said. we looked at for each other and knew something suddenly. the teacher went on, his reading punctuated by fits of laughter. “how wonderfully is the food cooked here everyday! what a great variety of dishes and how well your appetite is satisfied! it is only at our cafeteria you can find eating and enjoyable business. our cafeteria is so wonderful!” we burst into laugh at this time. according to this way of thing, how many smart, wise, perfect and funny articles could we find!
