AIR32的中断是和STM32一样的，所以标准库的函数也都是一样的，拿来直接用就行。因为是初学中断，所以air32的高级的中断优先级暂时没有啥太大用处，我也没那么多中断可以做。这里贴一下改的编码器计次的中断库

编码器中断计数库

#中断引脚是PA6,PA7
#include "air32f10x.h"                  // Device header

int16_t Encoder_Count;

{

	GPIO_InitStructure.GPIO_Mode = GPIO_Mode_IPU;
	GPIO_InitStructure.GPIO_Pin = GPIO_Pin_6|GPIO_Pin_7;
	GPIO_InitStructure.GPIO_Speed = GPIO_Speed_50MHz;
	GPIO_Init(GPIOA, &GPIO_InitStructure);
	
	GPIO_EXTILineConfig(GPIO_PortSourceGPIOA,GPIO_PinSource6);
	GPIO_EXTILineConfig(GPIO_PortSourceGPIOA,GPIO_PinSource7);
