求助：有关IAR仿真430时中断函数进不去的问题
今天参考了TI有关提供的ADC12的例程，想通过仿真来查看ADC12MEMx的转换结果，不过仿真的时候程序一直停留在main函数里面，根本没进中断服务函数，望大家帮忙看看到底是什么问题，simulation里的interrupt steup 的中断向量也已经设置成ADC12_VECTOR了，下面是代码//******************************************************************************//MSP-FET430P140 Demo - ADC12, Sequence of Conversions (non-repeated)
//
//Description: This example shows how to perform A/D conversions on a sequence
//of channels. A single sequence of conversions is performed - one conversion
//each on channels A0, A1, A2, and A3. Each conversion uses AVcc and AVss for
//the references. The conversion results are stored in ADC12MEM0, ADC12MEM1,
//ADC12MEM2, and ADC12MEM3 respectively and are moved to 'results[]' upon
//completion of the sequence. Test by applying voltages to pins A0, A1, A2,
//and A3, then setting and running to a break point at the "_BIC..."
//instruction in the ISR. To view the conversion results, open a watch window
//in debugger and view 'results' or view ADC12MEM0, ADC12MEM1, ADC12MEM2, and
//ADC12MEM3 in an ADC12 SFR window.
//This can run even in LPM4 mode as ADC has its own clock
//Note that a sequence has no restrictions on which channels are converted.
//For example, a valid sequence could be A0, A3, A2, A4, A2, A1, A0, and A7.
//See the MSP430x1xx User's Guide for instructions on using the ADC12.

} 看工程option中的debugger，driver设置如果为smulator的话，是进不去中断的；只有选择FET Debugger才行。 34071417 发表于 2012-4-16 23:24 static/image/common/back.gif

不行啊，刚我试了一下如果选择FET Debugger的话就进不去仿真界面了，我是通过烦烦真来查看ADC12MEMx里面的结果 你用的是IAR的话，仿真的话应该看不到吧 34071417 发表于 2012-4-17 09:31 static/image/common/back.gif

那请问怎样才能进去中断函数？还有在单信号多通道转换的时候 CSTARTADDx的值是不是按设置的初值后，转换完一个通道的值后就自加，为第二个转换做准备？ zhoufly 发表于 2012-4-17 12:21 static/image/common/back.gif
单纯仿真是不能近中断的的吧,要有目标板的
我把开发板插上以后还是不能进入中断，这到底怎么回事呢，是软件问题还是得要设置什么呢？ zhoufly 发表于 2012-4-17 12:44 static/image/common/back.gif
driver设置为FET Debugge?
总终端允许 _EINT(); 加没?
driver设置为FET Debugge时就没法进入仿真界面了，上面的是TI提供的例程，中断啥都设置好了，就是在仿真的时候进不去中断服务函数 zhoufly 发表于 2012-4-17 13:59 static/image/common/back.gif
连目标板,
给目标板供电
烧写程序,在线仿真
谢谢你的帮忙，不过我按照你的建议做了，结果还是一样
