RTC driver and EXTI->PR Topic is solved

[vrollei]

Hi,

What is the best place to define correct EXTI->PRx register for RTC driver / alarm line?

For example:
STM32L1 uses EXTI->PR register
and
STM32L4 uses EXTI->PR1

RTC and EXTI driver in version 19.1 support only EXTI->PR1 register

Thanks in advance!

Hi,

The PAL driver does it this way:

Code: Select all

/*===========================================================================*/
/* Driver local definitions.                                                 */
/*===========================================================================*/

/* Handling a difference in ST headers.*/
#if defined(STM32L4XX) || defined(STM32L4XXP)
#define EMR     EMR1
#define IMR     IMR1
#define PR      PR1
#define RTSR    RTSR1
#define FTSR    FTSR1
#endif

The same is also in stm32_exti.h:

Code: Select all

/* Handling differences in ST headers.*/
#if !defined(STM32L4XX) && !defined(STM32L4XXP)
#define EMR1    EMR
#define IMR1    IMR
#define PR1     PR
#define RTSR1   RTSR
#define FTSR1   FTSR
#endif

Probably it should only be in EXTI and other drivers should use it. I am looking into this.

Hi,

Fixed as bug #1022.

It should be fine in trunk and 19.1.x now, could you check?

Hi,

thanks a lot!

I will check it.

Hi,

it seems STM32L1xx/stm32_registry.h does not contain:

#define STM32_RTC_TAMP_STAMP_HANDLER
#define STM32_RTC_WKUP_HANDLER
#define STM32_RTC_ALARM_HANDLER
#define STM32_RTC_TAMP_STAMP_NUMBER
#define STM32_RTC_WKUP_NUMBER
#define STM32_RTC_ALARM_NUMBER
#define STM32_RTC_ALARM_EXTI
#define STM32_RTC_TAMP_STAMP_EXTI
#define STM32_RTC_WKUP_EXTI
#define STM32_RTC_IRQ_ENABLE()

Code: Select all

#define STM32_RTC_TAMP_STAMP_HANDLER        Vector48
#define STM32_RTC_WKUP_HANDLER              Vector4C
#define STM32_RTC_ALARM_HANDLER             VectorE4
#define STM32_RTC_TAMP_STAMP_NUMBER         3
#define STM32_RTC_WKUP_NUMBER               1
#define STM32_RTC_ALARM_NUMBER              2
#define STM32_RTC_ALARM_EXTI                17
#define STM32_RTC_TAMP_STAMP_EXTI           19
#define STM32_RTC_WKUP_EXTI                 20

Hi,

Fixed as bug #1023.

There were some other things missing too.
