紧急求助大家有关PIC16C57C.html">PIC16C57C移值到PIC16F57的问题：
先本人用PIC16C57编程，在PICMATE2002仿真器上仿真通过了，后用PICSTART PLUS上用PIC16F57-1烧写，烧写成功，但是在我用到线路板上时，却出现的现象没有反映，所有的功能按钮均无效，我选择的晶振是XT！我也实验过了其它的振荡方式，也不行！硬件没有问题，我用PIC16C57C.html">PIC16C57C实验时没有问题的，请问大家为什么这样？是哪些地方设置不对吗？我也看了从PIC16C57C.html">PIC16C57C移值到PIC16F57文档，没有提到在那里要改变啊？大家用碰到的给我指教啊！非常的谢谢！移植的文档具体如下：
TABLE 1: PIC16FC57C →PIC16F57 MIGRATION DIFFERENCES
TABLE 2: PIC16FC57C →PIC16F57 NEW FEATURES
Note 1: This DEVICE has been designed to perform to the parameters of its data sheet. It has been tested to an
electrical specification designed to determine its conformance with these parameters. Due to PROCESS
differences in the manufacture of this DEVICE, this DEVICE may have different performance characteristics
than its earlier version. These differences may cause this DEVICE to perform differently in your application
than the earlier version of this DEVICE.
2: The user should verify that the DEVICE oscillator starts and performs as expected. Adjusting the loading
CAPACITOR values and/or the Oscillator mode may be required.

作者： yewuyi 于 2006/11/11 14:48:00 发布：我是直接用代码烧没出问题你可以把程序调到MPLAB里面选择PIC16F57重新编译。不知道你程序是如何搞的？上电初始化要做好，建议你上电后初始化BANK和PAGE，并给出一段延迟时间，如果开WATCHDOG了，先把WATCHDOG关掉，另外你的编程器是什么牌子的
