stm8 STVD+Cosmic中断向量表
各位大大，我在调试stm8s105的时候，如何在中断向量表中设置自己的中断？我做的是一个旋转编码按键，PC4位中断输入，external_Interrupt应该放到什么位置？我看别人的程序：TIM4对应/*irq23*/，TLI对应/*irq0*/。
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 unexpected events during development,
it is recommended to set a breakpoint on the following instruction
*/
return;
}
extern void _stext(); /* startup routine */
struct interrupt_vector const _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 */
};
哈哈，我又自问自答了，个人觉得/*irq x */应该就是手册10.8中断映射里的中断向量号，应该能对应上0到24，剩下的应该是保留的吧？有知道的告诉我一下。 帮顶
