In your code we don’t see where you are defining the SPI functions like OpenSPI(), there are parameters you need to specify like frequency, slave or master etc. You must sonfigure the pins used as well for SPI communication: SDI, SDO, CS etc.

All these were defined in  spi1.h, OpenSPI.h and pin_manager.h when using MCC. You must do this using PIC18F Peripheral Libraries as we explained in this article: SPI Functions with PIC18F Peripheral Libraries
