【RISC-V MCU CH32V103测评】- 4：EXTI 开启查错之旅 [复制链接]

 

测试了一下这个文档的内容：《CH32V103应用教程——EXTI》，有两处报错：

 

../EXTI/main.c:3:30: error: 'NVIC_PriorityGroup_2' undeclared (first use in this function)
     NVIC_PriorityGroupConfig(NVIC_PriorityGroup_2);

 

../EXTI/main.c:7:31: error: 'SystemCoreClock' undeclared (first use in this function)
     printf("SystemClk:%d\r\n",SystemCoreClock);

 

直接从EXAM中将文件粘贴过来，错误更多：

“multiple definition of `main';” 这个是重复定义了main入口

是这个意思，但是重建了workspace都不行。不明白给的这些示例和教程是怎么做出来地。开始研究Assembly了，看来在这个API的包裹器上弄不出来什么名堂。
