STM8的C语言编程（1）－－基本程序与启动代码分析现在几乎所有的单片机都能用C语言编程了，采用C语言编程确实能带来很多好处，至少可读性比汇编语言强多了。在STM8的开发环境中，可以通过新建一个工程，自动地建立起一个C语言的框架，生成后开发环境会自动生成2个C语言的程序，一个是main.c，另一个是stm8_interrupt_vector.c。main.c中就是一个空的main()函数，如下所示：/*MAIN.Cfile**Copyright(c)2002-2005STMicroelectronics*/main(){while(1);}而在stm8_interrupt_vector.c中，就是声明了对应该芯片的中断向量，如下所示：/*BASICINTERRUPTVECTORTABLEFORSTM8devices*Copyright(c)2007STMicroelectronics*/typedefvoid@far(*interrupt_handler_t)(void);structinterrupt_vector{unsignedcharinterrupt_instruction;interrupt_handler_tinterrupt_handler;};@far@interruptvoidNonHandledInterrupt(void){/*inordertodetectunexpectedeventsduringdevelopment,itisrecommendedtosetabreakpointonthefollowinginstruction*/return;}externvoid_stext();/*startuproutine*/structinterrupt_vectorconst_vectab[]={{0x82,(interrupt_handler_t)_stext},/*reset*/{0x82,NonHandledInterrupt},/*trap*/{0x82,NonHandledInterrupt},/*irq0*/{0x82,NonHandledInterrupt},/*irq1*/{0x82,NonHandledInterrupt},/*irq2*/{0x82,NonHandledInterrupt},/*irq3*/{0x82,NonHandledInterrupt},/*irq4*/{0x82,NonHandledInterrupt},/*irq5*/{0x82,NonHandledInterrupt},/*irq6*/{0x82,NonHandledInterrupt},/*irq7*/{0x82,NonHandledInterrupt},/*irq8*/{0x82,NonHandledInterrupt},/*irq9*/{0x82,NonHandledInterrupt},/*irq10*/{0x82,NonHandledInterrupt},/*irq11*/{0x82,NonHandledInterrupt},/*irq12*/{0x82,NonHandledInterrupt},/*irq13*/{0x82,NonHandledInterrupt},/*irq14*/{0x82,NonHandledInterrupt},/*irq15*/{0x82,NonHandledInterrupt},/*irq16*/{0x82,NonHandledInterrupt},/*irq17*/{0x82,NonHandledInterrupt},/*irq18*/{0x82,NonHandledInterrupt},/*irq19*/{0x82,NonHandledInterrupt},/*irq20*/{0x82,NonHandledInterrupt},/*irq21*/{0x82,NonHandledInterrupt},/*irq22*/{0x82,NonHandledInterrupt},/*irq23*/{0x82,NonHandledInterrupt},/*irq24*/{0x82,NonHandledInterrupt},/*irq25*/{0x82,NonHandledInterrupt},/*irq26*/{0x82,NonHandledInterrupt},/*irq27*/{0x82,NonHandledInterrupt},/*irq28*/{0x82,NonHandledInterrupt},/*irq29*/};
