Macro Definition Documentation

◆ MODE_RESET

#define MODE_RESET   (0x80)

device mode: reset

Definition at line 116 of file w5100_regs.h.

◆ REG_MODE

#define REG_MODE   (0x0000)

mode

Definition at line 37 of file w5100_regs.h.

◆ S0_MR

#define S0_MR   (0x0400)

As we are using the device in MACRAW mode, we only need socket 0.mode
