原创 关于pic18f单片机程序的protues图搭建

按照这个程序搭建的protues图如图所示，但为什么仿真木有效果呢?Vcc该链接在何处，应该如何画出呢？

程序：

#include
#pragma udata

extern void _startup (void);        // See c018i.c in your C18 compiler dir
#pragma code _RESET_INTERRUPT_VECTOR = 0x000800
void _reset (void)
{
    _asm goto _startup _endasm
}
#pragma code

#pragma code _HIGH_INTERRUPT_VECTOR = 0x000808
void _high_ISR (void)
{
    ;
}

#pragma code _LOW_INTERRUPT_VECTOR = 0x000818
void _low_ISR (void)
{
    ;
}
#pragma code
