Question

AVR 单片机程序中#pragma interrupt_handler adc_isr:iv_ADC，后的iv_ADC这种中断是在哪查看到得？

是<iom16v.h>中的宏定义;
#define iv_RESET 1
#define iv_INT0 2
#define iv_EXT_INT0 2
#define iv_INT1 3
#define iv_EXT_INT1 3
#define iv_TIMER2_COMPA 4
#define iv_TIMER2_COMP 4
#define iv_TIM2_COMP 4
#define iv_TIMER2_OVF 5
#define iv_TIM2_OVF 5
#define iv_TIMER1_CAPT 6
#define iv_TIM1_CAPT 6
#define iv_TIMER1_COMPA 7
#define iv_TIM1_COMPA 7
#define iv_TIMER1_COMPB 8
#define iv_TIM1_COMPB 8
#define iv_TIMER1_OVF 9
#define iv_TIM1_OVF 9
#define iv_TIMER0_OVF 10
#define iv_TIM0_OVF 10
#define iv_SPI_STC 11
#define iv_USART_RX 12
#define iv_USART_RXC 12
#define iv_USART0_RX 12
#define iv_USART0_RXC 12
#define iv_USART_DRE 13
#define iv_USART_UDRE 13
#define iv_USART0_DRE 13
#define iv_USART0_UDRE 13

你的<iom16v.h>不全吧？
不知道你用的是不是ICCavr编译软件，ICCavr在ioXXXXv.h头文件中已经定义了
#define iv_ADC 15
一般形式是： iv_<中断向量名>，AD的中断向量源就是ADC，你可以看datasheet里中断向量表的中断源名
我的<iom16v.h>文件里有：

向量表自己查找
