解决 Zephyr 编译错误：重复定义符号 'pressButton' 和 'wasButtonPressed'

在 Zephyr 项目编译过程中，遇到了以下错误：

这个错误是链接器(ld)报告的，它表示在链接时出现重复定义的符号(函数、变量等)，这是因为同一个符号在多个目标文件中定义了多次。

具体来说，这个错误是因为在imu.c、io.c和application.c中都定义了pressButton和wasButtonPressed这两个函数，导致链接器无法确定使用哪个定义。

你需要在其中一个文件中将这些函数的定义删除或修改函数名，以解决这个问题。

另外，你的编译命令似乎很长，不太容易看出问题所在。你可以尝试使用更简单的命令来编译，或者使用类似于Makefile的构建系统来管理编译过程。
