Arduino ASCOM Focuser Pro2 DIY / Discussion / General Discussion: 'serialEvent' was not declared in this scope

Hello, I'm using DRV8825HW203-M-MT-F-BT , and myFP2_DRV8825HW203_298 firmware,
but arduino keeps telling me that

serialcomms.h:614:17: error: 'serialEvent' was not declared in this scope

 serialEvent();

I don't know how to fix it, can you tell me how?

Thank you.
