1、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 */ m
2、ain(){ 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
