I have just started on STr9 and using the example project on a HITOP5. I included TIM function to create PWM function. I also added TIM.h into the library.h. However i keep getting this '' main.c:164: undefined reference to `TIM_DeInit' Source/main.c:174: undefined reference to `TIM_Init' '' But i thought i included the library already?? THanks in advance for any help!! Lazycatnull
