} 学习。。。。 记号 顶一下吧。我就是做那种没有20M的示波器的，频带高固然好，但要钱买啊！而工具很多时候够用、合用就好。 确实，至少20M才有实用价值！一般晶振都是20M以下的！ 有点意思。 没细看，不过，200k的示波器，没什么实用价值，最多看看市电。
示波器起码20M才勉强可以看看，不然跟没有差不多。 mark 好强.哈哈 很好，很强大
拿了看看的说 The only thing you should take care when using 5V logic is to reduce LCD voltage to 3V level. This can be simply done by using two general purpose diodes connected in series. This provides approximately 1.4V drop.(呵呵，我不用翻译了)
网速慢的很，视频上传不上去，网站上有。 我只能找到他用下面这个板子接的

点击此处下载 ourdev_479101.pdf(文件大小:60K) (原文件名:8051sbc.pdf) 很有意思！！我去年也做了一个··是用MSP340F247做的··还得了奖的··但我还是觉得有问题··有时间交流一下嘛·· 看看！
