在对Quartus II工程编译时出现了如下的错误信息,见下图:
所建project用到了Pin_AE24管脚,但是该管脚时双功能管脚,因此在使用之前一定要注意对其进行相关的配置,即是使其为普通管脚还是第二功能管脚。
具体配置如下图:
![q2 编译出现 Can't place multiple pins assigned to pin location Fin_AE24 q2 编译出现 Can't place multiple pins assigned to pin location Fin_AE24](http://img.bimg.126.net/photo/1epJbJvWaUyfJ4cQD4gjuQ==/4562427897519917493.jpg)
点击图标或到菜单栏选择
或
![q2 编译出现 Can't place multiple pins assigned to pin location Fin_AE24 q2 编译出现 Can't place multiple pins assigned to pin location Fin_AE24](http://img.bimg.126.net/photo/z93J-QralQxBs66mI78naA==/4562427897519917494.jpg)
选择 Device and Pin Options
![q2 编译出现 Can't place multiple pins assigned to pin location Fin_AE24 q2 编译出现 Can't place multiple pins assigned to pin location Fin_AE24](http://img.bimg.126.net/photo/-SZ1bl_OwWIgzr3e6q1UQg==/4562427897519917495.jpg)
进入设置页面,选择Dual-Purpose
Pins标签项 对特殊双功能管脚进行相关配置进行相关配置
![q2 编译出现 Can't place multiple pins assigned to pin location Fin_AE24 q2 编译出现 Can't place multiple pins assigned to pin location Fin_AE24](http://img.bimg.126.net/photo/0BA9wNmhTRP37W2ZarS93Q==/4562427897519917496.jpg)
这样进行Compile后就不会出现上面提到的错误了,其他双功能管脚与此配置类同。
