这样不但让自己很累，也可能把别人耽误了，本来对别人可能是小事一桩，但对自己来说可能会很费力，这样就不如拒绝别人。
牺牲自己并不一定给别人带来很多好处，反而可能会带着牺牲朋友。——一个电视剧里说的，当时听到这句话心想：真他妈的说到劳资处理事情的关键了，真想亲那家伙一口，只可惜说话的是个老女人，不好看。

搞了一个星期，前两天把面阵的CCD给驱动起来了，来得有点容易了，当晚竟然失眠了，虽然半夜一点多才回去睡觉，但是睡到不到四点就醒了，再怎么睡也睡不着了，就闭着眼想很多事，心情舒畅无比，不到六点就爬起来洗脸刷牙，然后跑去饭堂打饭，结果刷卡机还没开电，不能打卡，就不能打饭，只好做在饭堂等到六点半才打了饭。总之，精神亢奋。

可是小小的胜利之后是无比的艰难，今天邮购了两百多块钱的元件，这两天调东西都很郁闷，昨天晚上差点烧掉FPGA，弄得晕乎乎的。今天调AD9200也没调出来，调着又干起了别的事，困了，就搞了下懒人61，又升级了一下，发觉这个软件只要打开工程，就有要升级的地方。

和自己的进度安排差得越来越多了。

我是怎么说快了一倍呢，怎么证明出来的呢？

大家可以试一下：做一个定时器中断，中断里先让IO口为0xFF，然后第二句就是让IO口为0；用示波器探头钩住IO口中的一个，观察脉冲高电平的宽度，


试用两种操作方式，用共用体方式操作高电平为3微秒，而用指针操作的方式高电平为6微秒。


哈哈，大家测试一下啊，想想原因啊，不知道编译器在里面怎么搞的啊。

想把15KHz边沿很陡峭的TTL方波变成24V的方波（其他幅度的都一样道理）

原来测试时的方案是用光耦，如图 光耦的放大

但是光耦响应速度达不到要求，只有1us左右，要求边沿陡峭就做不到了，实际测量根本就没发现出来波形（因为占空比很微小）

于是改成三极管来放大，效果很好，注意：Rofdup一定不能太大，高速方波的传输切忌使用大的电阻！ BJT的放大

一点经验，呵呵
