Detailed Description

lwIP Options Configuration.

Author

MCD Application Team

Default LwIP options used by the library. NO_SYS is set to 1 (no operating system). LwIP debug output is enabled unless NDEBUG is defined.

DHCP_DEBUG

#define DHCP_DEBUG   LWIP_DBG_DEFAULT

ETHERNET_RMII_MODE_CONFIGURATION

#define ETHERNET_RMII_MODE_CONFIGURATION   1

Enables the Ethernet peripheral in RMII mode. If not defined, MII mode will be enabled. Pin mapping must be configured for the selected mode (see PinMap_Ethernet in PeripheralPins.c).

HTTPD_USE_CUSTOM_FSDATA

#define HTTPD_USE_CUSTOM_FSDATA   0

Set this to 1 to include "fsdata_custom.c" instead of "fsdata.c" for the file system (to prevent changing the file included in CVS)

Value:

                                                   1   /* Prevent the same port to be used after reset.
                                                   Otherwise, the remote host may be confused if the port was not explicitly closed before the reset. */
