void Cpu_Interrupt(void)定义的应该是bean里面的吧，但是我始终在PE中CPU的下拉菜单项里面找不到Cpu_Interrupt函数啊，为什么呢？

函数说明里不是说了么，这个是PE的内部函数，不是提供给application的接口函数

请问一下，我买的ＤＳＰ５６Ｆ８０７ＥＶＭ，让他给进行技术支持，但是他说：＂很抱歉，SDK移植到PE的工作我们还没有做过，一般用户都是直接使用PE开发或全部自己写程序开发的，由于SDK属于很早就停止供应的软件产品我们也无法提供更多的支持，如果您需要更深入的软件支持请直接发送邮件到CW软件供应商，因为这个软件应该是付费才能够提供深入的开发和技术支持的。＂为什么会这样呢？

你联系的哪里？“CW软件供应商”就是freescale啊

[此贴子已经被作者于2008-12-22 15:19:33编辑过]

如果客户原来的项目是用SDK做的，是可以移植到新版本CW上的，这个过程很容易。其实麻烦的是怕不同版本的编译器可能引入一些麻烦。但是理论上来讲,SDK的移植是不会有太大问题的。

如果是新的开发，就不要用SDK了。

我很愿意帮助你，而且会尽最大的努力。但是我时间有限，一天最多过来看一两次，工作了的人没那么多时间喽。你可以短给我你的其他联系方式，我很久不用qq了

[此贴子已经被作者于2008-12-22 15:13:36编辑过]

因为我不知道你用什么方式进行联系，我这边什么方式都可以，如果可以的话，你告诉我你的联系方式，无论是MSN还是其他什么的．我的EMAIL:yugangeducn@163.com,我的手机：13770312925,你可以随时和我联系，本人姓喻，谢谢！

顶

谢谢，但是我再次发到support.asia@freescale.com，仍然没有收到编号，我用的是附件里面加载word的方式提问的．
