<>中断程序如下</P><P>#pragma CODE_SEG NON_BANKED<BR>interrupt&nbsp; void IRQ_ISR() {<BR>&nbsp;&nbsp;&nbsp; row_count++;（出值为1）<BR>&nbsp;&nbsp;&nbsp; if((row_count&gt;40)&amp;&amp;(row_count%20==0)&amp;&amp;(row_image&lt;300)){<BR>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; init_AD();<BR>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; for(line_sample=0;line_sample&lt;72;line_sample++){<BR>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; while(!ATD0STAT1_CCF0);<BR>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; sample_data[line_sample]=signal_in;<BR>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; }<BR>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; ATD0CTL2=0x00;<BR>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; row_image++;<BR>&nbsp;&nbsp;&nbsp; }<BR>&nbsp;&nbsp;&nbsp; if((row_count&gt;40)&amp;&amp;(row_count%20==2)&amp;&amp;(row_image&lt;11)){<BR>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; for(line_temp=0;line_temp&lt;78;line_temp++){<BR>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; image_data[row_image-1][line_temp]=sample_data[line_temp];<BR>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; }<BR>&nbsp;&nbsp;&nbsp; } <BR>&nbsp; }</P><P>帮我看看这个中断程序有没有问题！</P><P>为什么sample_data[line_sample]里什么也没有啊?<BR></P>

<>不够具体看不出....</P><P>1、进了中断吗？2、ATD有问题没有？3、摄像头工作正常不？4、signal_in是什么？5、还有一点是，在DEBUG里看变量的值，要不断地刷新！</P><P>&nbsp;</P>

<>进中断了，AD也能工作，摄像头也能正常工作，signal_in就是ATD0DR0L&nbsp; ！可是发送到串口显示就是只有00&nbsp; 用十六进制显示。</P>
