 - To test the ELM FatFs:

1. Please turn on the following defines in "rtconfig.h":

      #define EFM32_USING_SPISD

      #define RT_USING_DFS

      #define RT_USING_DFS_ELMFAT

      #define DFS_*

2. copy "bsp/efm32/copy_this_file_dfs_elm.c" to "components/dfs/filesystems/elmfat/"

3. rename it to "dfs_elm.c" replacing the original file

4. and then compile



 - To test the lwIP:

1. You should have a ENC28J60 Ethernet controller and connect it with your board properly

2. Please turn on the following defines in "rtconfig.h":

      #define EFM32_USING_ETHERNET

      #define RT_USING_LWIP

      #RT_LWIP_*

3. please also turn on the following define to use simple http server

      #define EFM32_USING_ETH_HTTPD

   or turn on the following defines to use EFM32 Ethernet utility functions (due to memory limitation, you may not turn on both)

      #define EFM32_USING_ETH_UTILS

      #define hostName 		"onelife.dyndns.org"	/* Please change to your own host name */

      #define userPwdB64 	"dXNlcjpwYXNzd2Q="	/* Please change to your own user name and password (base 64 encoding) */
