IAR编译问题，能通过编译，链接出错，能否帮忙看一下。

我们现在用Sharp的新MemoryLCD，1.28寸圆屏，直接移植的MSP430FR5969的Sharp96x96驱动，修改宽度值即可使用。但是编译时一直出错，请帮忙检查一下，谢谢。

1、重复定义的报错，查下全局变量的定义或引用，是不是放在了.h文件中，需要放到.C文件中

2、未定义的报错，查下是不是没有添加相应的头文件或者库文件

Yingtao,

这个是函数之类的有重定义的错误。

你应该在工程里面查找一下这些函数是否有重定义，或者多个头文件里面有声明。

重复定义

搜这个符号DisplayBuffer，看哪里出现了多次

其他函数类似方法处理
