Device Specific Initialization

netconfig.c

IP addresses and host names must differ from device to device. For the netlib Support SW the device specific settings are assigned to structure adapter_t in file netconfig.c. You may also store these settings in the FLASH memory and load it during start up. These variables can be used with the Hardware Initialization and Software Initialization function instead of defines.

Example netconfig.c:

 @details
  Define global variables for network configuration. Either use predefined
  settings, or read device specific settings from FLASH and store it into
  these variables before net_init() function call.
