RTCv2 and stm32_registry.h

[lilvinz]

Hi again,

STM32L4xx has RTC periodic wakeups. This seems to be wrong in the stm32_registry.h.
While researching this, i wondered why all stm32 do have STM32_RTC_HAS_INTERRUPTS set to FALSE even though at least some do have interrupts. Also in rtc_lld.h STM32_RTC_HAS_INTERRUPTS is used to set if the driver supports callbacks but there seems to be no implementation of rtc_lld_set_callback().

Cheers

Hi,

RTCv2s have their interrupt connected to EXTI, you need to use the EXT driver to handle the callback.

Thanks, that makes sense.

Still stm32_registry.h for STM32L4xx has to be changed to

Code: Select all

#define STM32_RTC_HAS_PERIODIC_WAKEUPS      TRUE

Cheers

Fixed, thanks.
