passing arguement 1 of 'HAL_RTC_GetTime' from incompatible pointer type

Senior II

Hi,

I am getting the below warning when I compile my application. However, HAL_RTC_GetTime API expects the first argument of type pointer to a RTC_HandleTypeDef structure, thats what I provide, but I get this warning as highlighted below.

Hello,

It seems a conflict between the first input argument of the callback and the definition of the global rtc handle declared in the top of your main.c:

/* Private variables ---------------------------------------------------------*/
RTC_HandleTypeDef hrtc;
void HAL_RTC_AlarmAEventCallback(RTC_HandleTypeDef *hrtc)
{

	printf("Alarm is triggered\n\r");
	HAL_GPIO_TogglePin(GPIOD, GPIO_PIN_14);

	RTC_TimeTypeDef RTC_TimeRead;
	RTC_DateTypeDef RTC_DateRead;


				HAL_RTC_GetTime(&hrtc, &RTC_TimeRead, RTC_FORMAT_BIN);
				HAL_RTC_GetDate(&hrtc, &RTC_DateRead,RTC_FORMAT_BIN);

So remove & before hrtc from here:

			HAL_RTC_GetTime(&hrtc, &RTC_TimeRead, RTC_FORMAT_BIN);
			HAL_RTC_GetDate(&hrtc, &RTC_DateRead,RTC_FORMAT_BIN);

input handle hrtc is already a pointer, so only remove the "&" for hrtc.

HAL_RTC_GetTime(hrtc, &RTC_TimeRead, RTC_FORMAT_BIN);

That is why I don't like HAL, as hrtc might be a handle, or a pointer to a handle.
In my C sources, pointers always start with "p", like phRtc, or pu32Var. 
It really helps to avoid these problems.

Note that the compiler was telling you that you were providing a pointer-to-pointer (double indirection):

It's not really the fault of HAL here.

This is in user code - so the user could have (should have?) chosen to use such a naming convention; eg,

void HAL_RTC_AlarmAEventCallback( RTC_HandleTypeDef *pHrtc )
{
	printf( "Alarm is triggered\n\r" );
	HAL_GPIO_TogglePin( GPIOD, GPIO_PIN_14 );

	RTC_TimeTypeDef RTC_TimeRead;
	RTC_DateTypeDef RTC_DateRead;

	HAL_RTC_GetTime( pHrtc, &RTC_TimeRead, RTC_FORMAT_BIN );
	HAL_RTC_GetDate( pHrtc, &RTC_DateRead, RTC_FORMAT_BIN );

 

Using the same name for a handle and a pointer as a function call argument - I've seen that in many Cube / HAL sources.
