在 CubeMX 生成的项目中，PCD_EP_TX_ADDRESS 是在哪里定义的？答案

【问题标题】：In a CubeMX-generated project, where is PCD_EP_TX_ADDRESS defined?在 CubeMX 生成的项目中，PCD_EP_TX_ADDRESS 是在哪里定义的？

【问题描述】：

我需要使用来自stm32f3xx_hal_pcd.h 的宏PCD_GET_EP_TX_ADDRESS。

定义为：

#define PCD_GET_EP_TX_ADDRESS(USBx, bEpNum) ((uint16_t)*PCD_EP_TX_ADDRESS((USBx), (bEpNum)))

但使用它会导致编译错误，因为未定义PCD_EP_TX_ADDRESS。

我已经对整个项目和字符串PCD_EP_TX_ADDRESS 进行了grep，结果如下：

在许多目标文件中存在该字符串，表明它是在某个位置定义的。

PCD_EP_TX_ADDRESS 在哪里定义？

【问题讨论】：

我用strings检查了两个.o文件，只发现了相同的宏定义。

标签： usb stm32 stm32f3

【解决方案1】：

它似乎是在stm32f3xx_hal_pcd_ex.h 内部声明的。

#define PCD_EP_TX_ADDRESS(USBx, bEpNum) ((uint16_t *)((uint32_t)((((USBx)->BTABLE+(bEpNum)*8)*2+     ((uint32_t)(USBx) + 0x400U)))))

它可能不包含在 CubeMX 中，因为 CubeMX 有时很垃圾。导出中有一些选项允许您包含比 cubemx 使用的更多的库部分。

请不要忘记在stm32<xx>xx_hal_conf.h内设置正确的HAL包含定义@
