(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?
I think you'll find that the function was merely declared - not defined.
ie, the header contained just the prototype for the function...
