avr gcc编译？有人能帮我吗

我在编译代码时遇到问题，它会显示以下错误：

main.c:33:5: warning: 'PORTE_INT0_vect' appears to be a misspelled signal handler
 ISR(PORTE_INT0_vect)
     ^
In file included from main.c:8:0:
main.h:15:19: error: 'PORTE' undeclared (first use in this function)
 #define DATA_PORT PORTE``
                   ^
main.c:35:11: note: in expansion of macro 'DATA_PORT'
   inbit = DATA_PORT.IN & DATA_PIN;
           ^
main.h:15:19: note: each undeclared identifier is reported only once for each function it appears in
 #define DATA_PORT PORTE
                   ^
main.c:35:11: note: in expansion of macro 'DATA_PORT'
   inbit = DATA_PORT.IN & DATA_PIN;

我在终端上写下：

avr-gcc -g -Os -mmcu=atmega32 -c main.c

谁能帮帮我，告诉我是什么问题吗？我是aver的新手，所以我对这个错误一无所知。 对不起，我的英语糟透了

您试图编译的代码是为ATxmega128编写的。这是一款与您使用的ATmega32完全不同的微控制器，并且没有相同的外围设备。例如，ATmega32只有GPIO端口PORTA到PORTD，并且完全缺少可编程多级中断控制器（PMIC）

---

如果可能的话，这段代码需要在微控制器上进行重大更改才能运行。这可能不是一个很好的介绍性项目。

添加一些代码片段会很有用，这样我们可以更好地了解正在发生的事情：）我刚刚发布了它作为我问题的答案。如果您有一个Atmega32，那么您需要使用另一个端口。如果您有一个具有PORTE的不同芯片，那么您需要将编译器参数设置为正确的处理器。如果您使用的是IDE中的某个选项卡，那么这可能是其中的某个选项卡。因此，我只需将PORTE更改为PORTA或PORTB，例如？其他错误呢？其他错误主要是因为Atmega32没有这些错误。您必须确定您拥有的处理器以及您拥有的处理器。（例如，如果要使用PORTB，则需要将导线连接到正确的引脚。）处理器的数据表中包含所有正确的术语拼写。
