<p>我试图用TMS320VC5509A驱动HT1621,可是不成功。<br style="overflow-wrap:break-word; word-break:break-all; color:#444444;Microsoft Yahei", Simsun; white-space:normal; background-color:#f2f9fd" />

我担心是这几句有问题。<br style="overflow-wrap:break-word; word-break:break-all; color:#444444;Microsoft Yahei", Simsun; white-space:normal; background-color:#f2f9fd" />
不知道5509有没有对IO口位操作的函数。<br style="overflow-wrap:break-word; word-break:break-all; color:#444444;Microsoft Yahei", Simsun; white-space:normal; background-color:#f2f9fd" />
请大神指教，谢谢！</p>
<p>只是建议</p>
<p>确保宏定义或函数调用正确，且用的端口和引脚编号与硬件设置匹配。</p>
<p>检查全局变量temp，它的值在代码中好像并没改变吧</p>
<p>谢谢！我改成类似这样就好了</p>
<p>temp&=0xfe;<br />
GPIO_RSET(IODATA,temp);</p>
<p> </p>
