用的是STM8L151K6
发现定时器不能中断，代码如下
extern @far @interrupt void time2_IRQHandler(void);
struct interrupt_vector const _vectab[] = {
 {0x82, (interrupt_handler_t)main}, /* reset */

已经搞了一个星期了，真的要崩溃了。是我的技术太菜了吗?确实是刚接触STM。哎！请高手指点一下啊
extern @far @interrupt void time2_IRQHandler(void);
有声明的，这个声明在STM_INTERRUUT_VECTOR.C中
会不会是单片机质量有问题或者烧录器有问题啊，用的是ST-LINK/V2
