when pickit3 first came out, I looked hard at it as a replacement / backup for my picket2. the reloading of os issue is a killer to me, and I am not sure what value a pickit3 adds over a pickit2 for the kind of chips I work with (12f675, 16f684, 16f886 and 16f1936).

  how you get the pic16f1936？ is it at sale in the chips market? or just sampling..

我在2个月前第一次使用PIC。说说我的感觉：


ICD2基本不能用做调试，速度慢，而且经常程序乱跑。


第一代icd2不好买到了据说，后来的和现在的icd2都不太稳定，老得拔插
===============================================================
是的。很不爽。老是出现：ICD0019: Communications:  Failed to open port (USB): (Windows::GetLastError() = 0x2, '系统找不到

不过调试（我用编程下去，再调试。ICD2的debug非常不好用，经常出错）时，使用MPLAB软件带的，release from reset 。不用拔调试口，出现找不到USB驱动的情况就不会那么频繁了。
还有就是，我使用我的古董IBM T30不会经常 出现找不到USB驱动，但使用台式机会。

pickit3 is newer, but each time you switch a chip, it has to download new os to the programmer,

ICD2 也需要
