VSCODE + EIDE 下 STM32 编程使用部分外设无法通过编译：undefined reference to ‘xxx‘

wonder-wall2025-06-20 8:47

我在配置某些外设时，敲代码时，代码提示能正常找到所有外设的库

编译时提示找不到 undefined reference to 'xxx_init' ，也就是没找到stm32f10x_xxx.c 。

同一个目录下的stm32f10x_tim.c却可以被找到。

临时解决方案

将stm32f10x_xxx.c复制到头文件的目录下

最终解决方案

发现是 EIDE 配置的问题。编译时 EIDE 默认将一些外设的库函数排除在外了，

在项目目录的.eide\eide.json 中：

json 复制代码

{
  ...
  "targets": {
    "Debug": {
      "excludeList": [
        "hal/STM32F10x_StdPeriph_Driver/src/stm32f10x_bkp.c",
        "hal/STM32F10x_StdPeriph_Driver/src/stm32f10x_can.c",
        "hal/STM32F10x_StdPeriph_Driver/src/stm32f10x_cec.c",
        "hal/STM32F10x_StdPeriph_Driver/src/stm32f10x_crc.c",
        "hal/STM32F10x_StdPeriph_Driver/src/stm32f10x_dac.c",
        "hal/STM32F10x_StdPeriph_Driver/src/stm32f10x_dbgmcu.c",
        "hal/STM32F10x_StdPeriph_Driver/src/stm32f10x_dma.c",
        "hal/STM32F10x_StdPeriph_Driver/src/stm32f10x_flash.c",
        "hal/STM32F10x_StdPeriph_Driver/src/stm32f10x_fsmc.c",
        "hal/STM32F10x_StdPeriph_Driver/src/stm32f10x_i2c.c",
        "hal/STM32F10x_StdPeriph_Driver/src/stm32f10x_iwdg.c",
        "hal/STM32F10x_StdPeriph_Driver/src/stm32f10x_pwr.c",
        "hal/STM32F10x_StdPeriph_Driver/src/stm32f10x_rtc.c",
        "hal/STM32F10x_StdPeriph_Driver/src/stm32f10x_sdio.c",
        "hal/STM32F10x_StdPeriph_Driver/src/stm32f10x_wwdg.c"
      ],
      ....
}

将 excludeList 中想要用到的库删除，再重新加载项目即可。
