mac + clion + platformio开发问题汇总

编译时找不到头文件问题

直接引入项目子目录头文件，总提示找不到文件

rc/main.c:5:10: fatal error: test.h: No such file or directory

在CMakeLists.txt里已经添加过include_directories,IDE没有报错，可以正确引用到，编译时就是找不到文件

include_directories(${CMAKE_CURRENT_SOURCE_DIR}/include/test)

查看终端执行命令

/Applications/CLion.app/Contents/bin/cmake/mac/bin/cmake --build /Users/shaun/CLionProjects/stmf103rc/cmake-build-genericstm32f103rc --target Production
[1/1] cd /Users/shaun/CLionProjects/stmf103rc && platformio -c clion run -egenericSTM32F103RC
FAILED: CMakeFiles/Production /Users/shaun/CLionProjects/stmf103rc/cmake-build-genericstm32f103rc/CMakeFiles/Production ....

调用cmake后，首先是执行platformio命令，会不会是platformio通过工具链执行编译时，没有把子目录include进去
通过查看platformio配置文档 https://docs.platformio.org/en/stable/projectconf/section_platformio.html#include-dir

默认只有include路径，添加在platformio.in里需要添加参数build_flags

[env:genericSTM32F103RC]
platform = ststm32
board = genericSTM32F103RC
framework = stm32cube
debug_tool = jlink
upload_protocol = jlink
build_flags = -I /path/to/dir

extra_scripts = post:extra_script.py

重复引用头文件问题

构建时报如下错误

 error: unknown type name 'HAL_StatusTypeDef'; did you mean 'FLASH_TypeDef'

参考：https://electronics.stackexchange.com/questions/443018/cube-ide-error-unknown-type-name-hal-statustypedef
原因是代码里重复引用了头文件，删掉一个就可以，比如下面的hal_tim.h

#include <stm32f1xx_hal.h>
#include <stm32f1xx_hal_tim.h>

HAL_Delay事件不对问题

函数没响应

• 检查是否调用HAL_Init()函数
• 检查是否实现void SysTick_Handler(void)函数

int main()
{
    HAL_Init();

    /* Configure the system clock */
    SystemClock_Config();
}

void SysTick_Handler(void)
{
    HAL_IncTick();
}

计时不对

HAL_Delay(1000)预期1秒，结果变成了2秒，没有正确配置时钟树参数
从STM32CubeMX配置好时钟树后，生成代码，将main.c里的SystemClock_Config()函数复制出来，在main()函数里调用即可

void SystemClock_Config(void)
{
    RCC_OscInitTypeDef RCC_OscInitStruct = {0};
    RCC_ClkInitTypeDef RCC_ClkInitStruct = {0};

    RCC_OscInitStruct.OscillatorType = RCC_OSCILLATORTYPE_HSE;
    RCC_OscInitStruct.HSEState = RCC_HSE_ON;
    RCC_OscInitStruct.HSEPredivValue = RCC_HSE_PREDIV_DIV1;
    RCC_OscInitStruct.HSIState = RCC_HSI_ON;
    RCC_OscInitStruct.PLL.PLLState = RCC_PLL_ON;
    RCC_OscInitStruct.PLL.PLLSource = RCC_PLLSOURCE_HSE;
    RCC_OscInitStruct.PLL.PLLMUL = RCC_PLL_MUL9;
    if (HAL_RCC_OscConfig(&RCC_OscInitStruct) != HAL_OK)
    {
        Error_Handler();
    }

    RCC_ClkInitStruct.ClockType = RCC_CLOCKTYPE_HCLK|RCC_CLOCKTYPE_SYSCLK
                                  |RCC_CLOCKTYPE_PCLK1|RCC_CLOCKTYPE_PCLK2;
    RCC_ClkInitStruct.SYSCLKSource = RCC_SYSCLKSOURCE_PLLCLK;
    RCC_ClkInitStruct.AHBCLKDivider = RCC_SYSCLK_DIV1;
    RCC_ClkInitStruct.APB1CLKDivider = RCC_HCLK_DIV2;
    RCC_ClkInitStruct.APB2CLKDivider = RCC_HCLK_DIV1;

    if (HAL_RCC_ClockConfig(&RCC_ClkInitStruct, FLASH_LATENCY_2) != HAL_OK)
    {
        Error_Handler();
    }
}
