unknown type name 'ADC_HandleTypeDef'

Hi,

I am trying to add the ADC handles into a struct that is in a seperate header file. For some reason I cannot get the ADC handles' typedef to be located after including  stm32f4xx_hal.h.

My struct looks is as follows 

typedef struct mouse_device{

   const ADC_HandleTypeDef* adc_x;    const ADC_HandleTypeDef* adc_y;

   signed long x_cal;

   signed long y_cal;

   mouse_buf_t mouse_buf;

} mouse_device_t;

And at the top of the header I have only one include and that is &sharpinclude 'stm32f4xx_hal.h'

I am a little confused as to why it does not work as after tracing though the headers the stm32f4xx_hal leads to the adc header which contains the typedef.

Cheers#include #adc #hal

Hello!

Inside 'stm32f4xx_hal_conf.h'  the definition #define HAL_ADC_MODULE_ENABLED must be uncommented to include the stm32f4xx_hal_adc.h which contains the typedef.

Also USE_HAL_DRIVER defined. Confirm HSE_VALUE is consistent with board.

Thanks for the reply. The ADC is indeed enabled. I am using the ADC handles in my main.c but in this header they cannot be resolved.

The Hal driver is being used yes. I imagine the HSE values should match. All of the config code as well as the ADC handles were generated using cube.
