keil编译器出现问题，根据提示意思就是ARM编译器选择不对的问题。
| *** Target 'Printf' uses ARM-Compiler 'V5.06 update 1 (build 183)' which is not available. *** Please review the installed ARM Compiler Versions: 'Manage Project Items - Folders/Extensions' to manage ARM Compiler Versions. 'Options for Target - Target' to select an ARM Compiler Version for the target. *** Rebuild aborted. Build Time Elapsed: 00:00:00 |
解决办法点击options of target 在ARM Compiler选项里面选择ARM编译器版本，一般选择默认的就好。
如图
