Hi expert,
I have a customer want to inline a function in the ISR.
and they declare the function in the Drv_capture.h file.

define the function in Dri_capture.c file.

and then reference the function in ISR.C file. the interrupt function “cputimer_10KHz_ISR” to call this function : get_Fan_Speed();
Also include the Drv_capture.h file.

but build fail to find get_Fan_Speed();

I also suggest customer to add extern for the declaration in Drv_capture.h file. But the error is still.
so can you tell where I did wrong?
