战舰STM32F103开发板源代码USB库函数疑问

lindahnu

在头文件usb_regs.h里有这两个宏定义，标红色的地方是不是有错误，应该改成dwReg吧？

#define _BlocksOf32(dwReg,wCount,wNBlocks) {\
    wNBlocks = wCount >> 5;\
    if((wCount & 0x1f) == 0)\
      wNBlocks--;\
    *pdwReg = (uint32_t)((wNBlocks << 10) | 0x8000);\
  }/* _BlocksOf32 */

#define _BlocksOf2(dwReg,wCount,wNBlocks) {\
    wNBlocks = wCount >> 1;\
    if((wCount & 0x1) != 0)\
      wNBlocks++;\
    *pdwReg = (uint32_t)(wNBlocks << 10);\
  }/* _BlocksOf2 */

如果传入的参数是指针变量的话就没问题

正点原子

编译不报错就没问题
