驱动库driverlib文件夹内的rom.h是干什么用的?
我看到有“
#define ROM_APITABLE ((unsigned long *)0x01000010)
#define ROM_ETHERNETTABLE ((unsigned long *)(ROM_APITABLE[15]))
#define ROM_EthernetPacketPutNonBlocking ((long (*)(unsigned long ulBase, unsigned char *pucBuf, unsigned long lBufLen))ROM_ETHERNETTABLE[12])
”
为什么要这样处理,这个无名的函数与同文件夹下的ethernet.c文件中的EthernetPacketPutNonBlocking有区别么? |
