*** EFM32 branch *** 

1. Add ENC28J60 Ethernet controller driver 
2. Add lwIP support (Please read "Readme.txt")
3. Add simple Http server demo application
4. Modify USART device write function to avoid sleep in ISR
5. Fix a bug in USART driver when using compiler optimization
6. Modify to make use the start-up code in libraries
7. Change the default build option for squeezing the executable file size
8. Modify source code alignment

To test the ELM FatFs:
1. Please copy "bsp/efm32/copy_this_file_dfs_elm.c" to "components/dfs/filesystems/elmfat/"
2. rename it to "dfs_elm.c" replacing the original file
3. and then compile
Warning:
FatFs is really FAT! (35KB)
You may remove the following defines in "rtconfig.h" to save space:
//#define RT_MEM_DEBUG
//#define THREAD_DEBUG
//#define IRQ_DEBUG
//#define RT_IRQHDL_DEBUG
//#define RT_IIC_DEBUG
//#define RT_MISC_DEBUG
//#define RT_ADC_DEBUG
//#define RT_ACMP_DEBUG
//#define RT_TIMER_DEBUG
//#define RT_RTC_DEBUG
- 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
//#define RT_USING_EVENT
//#define RT_USING_MAILBOX
//#define RT_USING_MESSAGEQUEUE
//#define RT_USING_MEMPOOL
//#define RT_USING_IIC0 0x1UL
//#define RT_USING_ACMP0

//#define RT_USING_TIMER2 (0x00) /* Continuous mode */
//#define RT_USING_RTC
//#define EFM32_USING_SFLASH
\ No newline at end of file
- 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_*
