(Using Cortex M4) and Keil uVision 4.20.03.0
I get error :
.\Armboard\Armboard.axf: Error: L6218E: Undefined symbol TimingDelay_Decrement (referred from stm32f4xx_it.o).
whenever I build target. In the file there is an #include "main.h" where the function is clearly defined, however I still get this error.
Any help?
This isn't a compiler error. This is a linker error. So have you configured your project to to compile and link that other source file? So the linker will see the *.o file that contains the generated code for that function?
The project clearly links the source file. main.h is in the file tree generated by the linker.
