STM32H743移植Lora模块sx1278驱动 multiply defined 错误

       近期得空试用一下Lora模块，Ai-Thinker的Ra-01模块,SPI接口。工具为STM32CubeMX V5.5.0 +Keil V 5.29；sx1278驱动为官方STM32驱动。因手头现有电路板因素，计划使用STM32F051+SX1278实现Lora接收，用STM32H743+SX1278实现Lora发送。
STM32F051很顺利的完成驱动移植与接收功能。但在STM32H743上却碰上了链接错误。始终摸不着头脑。（H7的大炮打这个sx1278蚊子，活不好干）
      特来向大神们求助。
      附上整个工程文件（STM32CubeMX +Keil）。各位过路大神，得空帮忙研究研究。不胜感激！

求助的附件下载咋还要扣分？又找不到在哪修改。新手发贴，见谅！

补充说明一下，这些错误无法Keil定位。貌似是跟<math.h>库的调用有关。可却找不到错误原因。

pxforever 发表于 2020-4-1 18:32:15

是的，和math.h文件有关，还可能和使用了C99 mode相关，应该是代码某些头文件重复包含问题，加上math中的命名空间问题
