..\FWLIB\src\stm32f4xx_fmc.c(676): error: #20: identifier "FMC_Bank4" is undefined
时间: 2023-08-12 11:04:50 浏览: 382
根据你提供的错误信息,编译器报告了一个标识符未定义的错误。这意味着在 stm32f4xx_fmc.c 文件的第676行中,标识符 "FMC_Bank4" 未被定义。
要解决这个问题,你需要确保在代码中包含了定义 "FMC_Bank4" 的头文件,并且该标识符在代码中被正确定义和初始化。
另外,如果你正在使用外部库或库函数,请确保已正确链接该库,并且链接器可以找到库文件。
如果 "FMC_Bank4" 是由你自己定义的宏或变量名,那么请检查是否正确定义了该标识符,并且在使用之前进行了适当的声明或初始化。
如果你需要进一步的帮助,请提供更多关于你的代码和编译器/开发环境的细节,以便我能更好地帮助你解决问题。

..\Libraries\FWlib\src\stm32f4xx_fmc.c(195): error: #20: identifier "FMC_BCR1_MBKEN" is undefined
这个错误是由于在文件"stm32f4xx_fmc.c"的第195行使用了未定义的标识符"FMC_BCR1_MBKEN"引起的。这个标识符可能是在其他地方定义的,但是在当前文件中没有找到。
要解决这个问题,你可以按照以下步骤进行操作:
1. 确保你已经包含了正确的头文件,这些头文件应该包含FMC相关的定义和声明。
2. 检查你是否正确地初始化了FMC控制器,在初始化过程中应该包含对"FMC_BCR1_MBKEN"标识符的定义。
3. 如果你的代码中确实没有对"FMC_BCR1_MBKEN"的定义,那么你可能需要查看设备的文档或参考其他示例代码,找到正确的定义并添加到代码中。
希望这些提示能够帮助你解决问题!如果你还有其他问题,请继续提问。

你提供的这个 `stm32f4xx_conf.h` 是 **标准外设库(StdPeriph)** 的配置头文件,而不是 HAL 库使用的配置文件。你在使用 HAL 库开发时不应该包含这些 StdPeriph 风格的 `.h` 文件。
---
## ✅ 你需要做的事情:
### 🔥 删除所有 StdPeriph 相关的 `#include` 行
在你的 `stm32f4xx_conf.h` 中,保留以下这一行即可:
```c
#include "stm32f4xx_hal.h"
```
然后 **删除或注释掉其他所有 `#include` 行**,因为它们都属于标准外设库,与 HAL 库冲突。
---
## ✅ 修改后的 `stm32f4xx_conf.h` 示例
```c
#ifndef __STM32F4xx_CONF_H
#define __STM32F4xx_CONF_H
/* Includes ------------------------------------------------------------------*/
#include "stm32f4xx_hal.h"
/* Exported types ------------------------------------------------------------*/
/* Exported constants --------------------------------------------------------*/
/* If an external clock source is used, then the value of the following define
should be set to the value of the external clock source, else, if no external
clock is used, keep this define commented */
/*#define I2S_EXTERNAL_CLOCK_VAL 12288000 */ /* Value of the external clock in Hz */
/* Uncomment the line below to expanse the "assert_param" macro in the
Standard Peripheral Library drivers code */
/* #define USE_FULL_ASSERT 1 */
/* Exported macro ------------------------------------------------------------*/
#ifdef USE_FULL_ASSERT
/**

*/
#define assert_param(expr) ((expr) ? (void)0 : assert_failed((uint8_t *)__FILE__, __LINE__))
/* Exported functions ------------------------------------------------------- */
void assert_failed(uint8_t* file, uint32_t line);
#else
#define assert_param(expr) ((void)0)
#endif /* USE_FULL_ASSERT */
#endif /* __STM32F4xx_CONF_H */
```

## 🚫 被删除的 StdPeriph 头文件列表(应避免引用)
你应该删除或注释掉如下这些行:
```c
#include "stm32f4xx_crc.h"
#include "stm32f4xx_dbgmcu.h"
#include "stm32f4xx_dma.h"
#include "stm32f4xx_exti.h"
#include "stm32f4xx_flash.h"
#include "stm32f4xx_gpio.h"
#include "stm32f4xx_i2c.h"
#include "stm32f4xx_iwdg.h"
#include "stm32f4xx_pwr.h"
#include "stm32f4xx_rcc.h"
#include "stm32f4xx_rtc.h"
#include "stm32f4xx_sdio.h"
#include "stm32f4xx_spi.h"
#include "stm32f4xx_syscfg.h"
#include "stm32f4xx_tim.h"
#include "stm32f4xx_usart.h"
#include "stm32f4xx_wwdg.h"
#include "misc.h"
```
以及所有:
```c
#if defined (STM32F429_439xx)
#include ...
#endif
```
这类条件编译的 StdPeriph 模块。

## ✅ 总结:修改点一览
| 原始内容 | 是否保留 | 原因 |
|----------|----------|------|
| `#include "stm32f4xx_hal.h"` | ✅ 保留 | HAL 库主头文件 |
| 所有其他 `#include` | ❌ 删除/注释 | 属于 StdPeriph,与 HAL 冲突 |
| `USE_FULL_ASSERT` 宏定义 | 可选保留 | 控制断言是否启用 |
| `assert_param()` 宏定义 | ✅ 保留 | 断言宏对调试有用 |
