表示超级反感在串口在使用while!

有同感，在串口中加入while，那不就成在那傻等了嘛，对于实时性影响很大。 在PE配置中开启串口中断。定义中断的函数名称。
在工程上右击，选择properties。
在其中processor expert选项中选择generate ISRs。生成代码。
然后在events.c中找生成的中断函数，按照正常的用法使用就可以。

我这里没有装KDS，这里面使用PE的话会生成events.c这个文件吗。如果能生成，那用法应该是一样的。就是普通中断函数的用法，产生中断之后自动调用中断函数，进入中断之后清除中断标志，然后就该干嘛就干嘛了。 lz可以在kds或cw的example中找下，有没有例程，拷贝复制一下即可。 daicp 发表于 2014-9-25 08:37

是PE中使能中断，然后在Event.c会有对应的中断函数与其对应。 FSL_TICS_ZP 发表于 2014-9-25 15:59
