# 在使用RT-Thread Studio 生成STM32H7项目时ADC配置错误
## 生成的adc_config.h中的ADC_CONFIG结构体不是H7的

### 生成的代码是

```c
#define ADC1_CONFIG                                                 \
    {                                                               \
       .Instance                   = ADC1,                          \
       .Init.ClockPrescaler        = ADC_CLOCK_SYNC_PCLK_DIV4,      \
       .Init.Resolution            = ADC_RESOLUTION_12B,            \
       .Init.DataAlign             = ADC_DATAALIGN_RIGHT,           \
       .Init.ScanConvMode          = DISABLE,                       \
       .Init.EOCSelection          = DISABLE,                       \
       .Init.ContinuousConvMode    = DISABLE,                       \
       .Init.NbrOfConversion       = 1,                             \
       .Init.DiscontinuousConvMode = DISABLE,                       \
       .Init.NbrOfDiscConversion   = 0,                             \
       .Init.ExternalTrigConv      = ADC_SOFTWARE_START,            \
       .Init.ExternalTrigConvEdge  = ADC_EXTERNALTRIGCONVEDGE_NONE, \
       .Init.DMAContinuousRequests = DISABLE,                       \
    }
```
### 而正确的h7的adc_config.h应该是

![screenshot_96a06dfab623d60a4b46c88e1f6f125e.png](https://oss-club.rt-thread.org/uploads/20230730/96a06dfab623d60a4b46c88e1f6f125e.png.webp)
### 正确代码

```c
#define ADC1_CONFIG \
 { \
 .Instance = ADC1, \
 .Init.ClockPrescaler = ADC_CLOCK_SYNC_PCLK_DIV4, \
 .Init.Resolution = ADC_RESOLUTION_16B, \
 .Init.ScanConvMode = ADC_SCAN_DISABLE, \
 .Init.EOCSelection = ADC_EOC_SINGLE_CONV, \
 .Init.LowPowerAutoWait = DISABLE, \
 .Init.ContinuousConvMode = DISABLE, \
 .Init.NbrOfConversion = 1, \
 .Init.DiscontinuousConvMode = DISABLE, \
 .Init.NbrOfDiscConversion = 1, \
 .Init.ExternalTrigConv = ADC_SOFTWARE_START, \
 .Init.ExternalTrigConvEdge = ADC_EXTERNALTRIGCONVEDGE_NONE, \
 .Init.ConversionDataManagement = ADC_CONVERSIONDATA_DR, \
 .Init.Overrun = ADC_OVR_DATA_OVERWRITTEN, \
 .Init.OversamplingMode = DISABLE, \
 }
```
## 我测试了一些情况
- RT-Thread Studio 生成STM32H753IITx芯片工程 生成代码错误
- RT-Thread Studio 生成STM32H743AGIx芯片工程 生成代码错误
- RT-Thread Studio 生成STM32H743-ATK-APOLLO开发板工程 BSP:1.0.2 RT-Thread:4.1.0 生成代码错误
- ENV工具在RT-Thread 4.1.1源码中在BSP stm32h743-atk-apollo 中 scons --dist生成工程中 生成代码正确

## 生成的库问题
不仅仅是adc_config.h问题,在drv_adc.c中
生成的代码是

```c
static rt_err_t stm32_adc_enabled(struct rt_adc_device *device, rt_uint32_t channel, rt_bool_t enabled)
{
    ADC_HandleTypeDef *stm32_adc_handler;
    RT_ASSERT(device != RT_NULL);
    stm32_adc_handler = device->parent.user_data;

if (enabled)
    {
#if defined(SOC_SERIES_STM32L4) || defined(SOC_SERIES_STM32G0)
        ADC_Enable(stm32_adc_handler);
#else
        __HAL_ADC_ENABLE(stm32_adc_handler);
#endif
    }
    else
    {
#if defined(SOC_SERIES_STM32L4) || defined(SOC_SERIES_STM32G0)
        ADC_Disable(stm32_adc_handler);
#else
        __HAL_ADC_DISABLE(stm32_adc_handler);
#endif
    }

return RT_EOK;
}
```
而正确的应该是

```c
static rt_err_t stm32_adc_enabled(struct rt_adc_device *device, rt_uint32_t channel, rt_bool_t enabled)
{
    ADC_HandleTypeDef *stm32_adc_handler;
    RT_ASSERT(device != RT_NULL);
    stm32_adc_handler = device->parent.user_data;

if (enabled)
    {
#if defined(SOC_SERIES_STM32L4) || defined(SOC_SERIES_STM32G0) || defined (SOC_SERIES_STM32MP1) || defined(SOC_SERIES_STM32H7) || defined (SOC_SERIES_STM32WB)
        ADC_Enable(stm32_adc_handler);
#else
        __HAL_ADC_ENABLE(stm32_adc_handler);
#endif
    }
    else
    {
#if defined(SOC_SERIES_STM32L4) || defined(SOC_SERIES_STM32G0) || defined (SOC_SERIES_STM32MP1) || defined(SOC_SERIES_STM32H7) || defined (SOC_SERIES_STM32WB)
        ADC_Disable(stm32_adc_handler);
#else
        __HAL_ADC_DISABLE(stm32_adc_handler);
#endif
    }

return RT_EOK;
}
```
修改了这些后才编译通过
### 这个 studio 生成的工程问题很大,我目前只测试adc就遇到了这些问题,其他功能没有测试,没有启用,估计也是有错的. 希望官方早点修复,非常影响使用!
