HAL_RTCEx_SetCoarseCalib() function

Sets the Coarse calibration parameters.

Syntax

HAL_StatusTypeDef HAL_RTCEx_SetCoarseCalib(RTC_HandleTypeDef *hrtc,     uint32_t CalibSign,     uint32_t Value);
Implemented in stm32f4xx_hal_rtc_ex.c:1302

Arguments

hrtc

pointer to a RTC_HandleTypeDef structure that contains the configuration information for RTC.

CalibSign

Specifies the sign of the coarse calibration value. This parameter can be one of the following values: @arg RTC_CALIBSIGN_POSITIVE: The value sign is positive @arg RTC_CALIBSIGN_NEGATIVE: The value sign is negative

Value

value of coarse calibration expressed in ppm (coded on 5 bits).

Return value

HAL status

Notes

This Calibration value should be between 0 and 63 when using negative sign with a 2-ppm step. This Calibration value should be between 0 and 126 when using positive sign with a 4-ppm step.
