编码电位器驱动

请问各位大神：STM8如何驱动编码电位器，需要中断吗？我是初学者，请各位大神多多指教

@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, (interrupt_handler_t)main}, /* reset */
    {0x82, NonHandledInterrupt}, /* trap */
    //{0x82, NonHandledInterrupt}, /* irq0 - tli */
                {0x82, NonHandledInterrupt}, /* irq0 - tli */
    {0x82, NonHandledInterrupt}, /* irq1 - awu */
    {0x82, NonHandledInterrupt}, /* irq2 - clk */
    {0x82, NonHandledInterrupt}, /* irq3 - exti0 */
    {0x82, REMOTE_IRQHandler}, /* irq4 - exti1 */
    {0x82, KEY_IRQ}, /* irq5 - exti2 */
    {0x82, NonHandledInterrupt}, /* irq6 - exti3 */
    {0x82, RotaryEncoder_IRQHandler}, /* irq7 - exti4 */
    {0x82, NonHandledInterrupt}, /* irq8 - can rx */
    {0x82, NonHandledInterrupt}, /* irq9 - can tx */
    {0x82, NonHandledInterrupt}, /* irq10 - spi*/
    {0x82, TIM1_IRQHandler}, /* irq11 - tim1 */
    {0x82, NonHandledInterrupt}, /* irq12 - tim1 */
    {0x82, TIM2_IRQHandler}, /* irq13 - tim2 */
    {0x82, NonHandledInterrupt}, /* irq14 - tim2 */
    {0x82, TIM3_IRQHandler}, /* irq15 - tim3 */
    {0x82, NonHandledInterrupt}, /* irq16 - tim3 */
    {0x82, NonHandledInterrupt}, /* irq17 - uart1 */
    {0x82, NonHandledInterrupt}, /* irq18 - uart1 */
    {0x82, NonHandledInterrupt}, /* irq19 - i2c */
    {0x82, NonHandledInterrupt}, /* irq20 - uart2/3 */
    {0x82, UART2_IRQHandler}, /* irq21 - uart2/3 */
    {0x82, NonHandledInterrupt}, /* irq22 - adc */
    {0x82, NonHandledInterrupt}, /* irq23 - tim4 */
    {0x82, NonHandledInterrupt}, /* irq24 - flash */
    {0x82, NonHandledInterrupt}, /* irq25 - reserved */
    {0x82, NonHandledInterrupt}, /* irq26 - reserved */
    {0x82, NonHandledInterrupt}, /* irq27 - reserved */
    {0x82, NonHandledInterrupt}, /* irq28 - reserved */
    {0x82, NonHandledInterrupt}/* irq29 - reserved */
};

还有一个问题是这个中断向量表里面有优先级吗？编码器需要中断的话，应该把中断程序放在哪里？

你说的编码电位器没用过，但是芯片的中断优先级就了解一些。一般用到的普通中断可以通过软件设置优先级配置，实现灵活的嵌套。软件库中有对应的函数。
