Answer 1

你的确贺启定是错误的，你所使用的的确是评估版，因为调试信息已经明确的这么说了，快去网上找个注册机注册一下就可以了。禅绝如
ISR一般是指中断函数，从调试信息中看，是中断程序和其他的程序嵌套调用了某些函数宏中，所以才会有警告的。

Answer 2

1.首先，你用的Keil是评估芦散版的局毁，有2kB代码大小限制。去找个破解版的吧……
2.ISR所调用的子程序最好单独封成块，避免陪腊氏嵌套调用。

追问

多谢你的指点 但是我确定我的keil 不是评估版的 之前我自己也查了相关的资料 也已经重新下载过keil了 还是存在问题 另外 我想了解一下 2中ISR是指我自己编写的函数吗？ 我并没有写过以ISR命名的函数啊 还望高手赐教
