动手焊了个PIC最小系统，却开不起来，请高手指点。附图！

原理图也有！焊接介绍也有，可为什么就是下载不了程序？？？为什么呢？我不知道有没有焊错，那水晶插口哪里，MPLAB 的提示是：

说明下，最边边的那个灯是电源指示灯！通电后就有。在原理图中忘了添加进去！呵呵。

电路图纸有些模糊，因为有些大，在图上用鼠标点下就可以看完整的图。

小弟再此谢谢大家了！！！！！！

就是通信不上。显示说ICD 2 找不到目标。
当然我是选择了芯片的，现在在这里问的就是大家看看我硬件搞的有没有错误，有没有焊错。

5条线一一测量

有无搞反

只看该作者 · 2010-1-23 21:07

怎么测？？？？说明下？

我的接线的线序就是刚才我我拍的那张照片，名叫焊接的那个。你看下，有什么什么问题。

只看该作者 · 2010-1-23 21:13

原理图有没有问题？先帮我分析下。

1。我的那LED 是 1。8V 的压降，我量过的，所以限流电阻是取的是 681R 的电阻。
2。那个水晶头接头那里焊接是不是正确的？？？

唉，芯片是16C57吗？这个不能用ICD的约

只看该作者 · 2010-1-24 11:02

不是，芯片是 PIC16F57。

不是 16C57 。

仿真机是 MICROCHIP 官方的 MPLAB ICD 2。
先帮我看下硬件连接有没有问题。谢了

:D出现Warning52是最麻烦的事了!!!

1.测量目标板CPU是否有5V电压.
2.是否遵循MCLR,+,GND,RB7,RB6这个顺序.不过从你的原理图看,RB6和RB7的顺序是错了
3.ICD2与目标板单片机的这5个脚是否有断线.
4.目标板单片机坏了.
5.给ICD2重新下载程序.
6.扔掉ICD2.
