最后出现没找到器件

如果直接编程的话,就出现:

问一下,这到底是那部分出现问题了?

 

谢谢!!

软件不认识你这个器件，楼主最好确认一下你这个器件的好坏以及外围电路的连接

nicat2004

谢谢了,现在换了台机器,刚开始的时候能检测到器件而且是正确的,但下载时,出现DONE没有GO HIGH,下载失败,再后来就又出现和以前一样的了,一直是UNKNOWN DEVICE,这个是不是下载电缆有问题啊?或者是电脑并口有问题呢?

stone133

如果你用的是40来块钱的那种下载线，是很容易出现问题，可以换一个试试看；

如果没有条件更换，打开那个盒子看看接触方面有问题没有；

这个下载线的电源是由板子提供，并不是由并口提供的，一般来说这个电源如果过低，就会出现问题（下载线那个小盒子里面有一个驱动芯片，该芯片的供电就来自板子，芯片的型号类型可以查查，并不是所有电压都能满足的）；

如果上面都没有问题，你又有舍得，试着把这个电缆截掉一段，留下1/2到2/3左右就可以；

我是天才
