Please see pins in the examples. In dmd_momochrome.ino:

#define DMD_PIN_A PA1
#define DMD_PIN_B PA4
#define DMD_PIN_nOE PB1
#define DMD_PIN_SCLK PA15

// pins for SPI connect
// SPI specific pins as CLK and R_DATA has predefined values:
//   for SPI(1) CLK = PA5  R_DATA = PA7
//   for SPI(2) CLK = PB13  R_DATA = PB15

C ____?

Monochrome panels doesn't have a pin C.
