STM8的C语言编程
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.C file _
_ Copyright (c) ____-____ STMicroelectronics _/ 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:
/_ BASIC INTERRUPT VECTOR TABLE FOR STM8 devices _ Copyright (c) ____ STMicroelectronics _/
typedef void @far (_interrupt_handler_t)(void);
struct interrupt_vector {
unsigned char interrupt_instruction; interrupt_handler_t interrupt_handler; };
@far @interrupt void NonHandledInterrupt (void) {
/_ in order to detect une_pected events during development, it is recommended to set a breakpoint on the following instruction _/ return;
