Hi ST team,I referred the Application notes from the ST's for RTC temperature compensation Using STM8AL3189 MCU , Which has both positive and negative ppm compensation using CALM and CALPFrom the APP notes, ACC(ppm) = crystal deviation + k * (T -T0)^...
I am using this code:void main(){CLK_RTCClockConfig(CLK_RTCCLKSource_LSI, CLK_RTCCLKDiv_1);CLK_PeripheralClockConfig(CLK_Peripheral_RTC, ENABLE);RTC_WakeUpClockConfig(RTC_WakeUpClock_CK_SPRE_16bits);RTC_ITConfig(RTC_IT_WUT, ENABLE); <================...
Hi Team,I need some help to understand what I am doing is correct or wrong. A required guide from ST's expert Basically working on RTC temperature Drift compensation, so I have referred the RTC temperature compensation APP document from ST's The link...
The data sheet for this part says that after power loss the HT bit is set, and any reads of the clock will return the time of the last read. Then after the HT bit is cleared one should be able to read the current time since the clock is battery backe...
In the STM8L SDK, the RTC_WakeUpCmd() function can return an ERROR if the WUTWF bit fails to be set after a delay. In the RM there's no mention of how and why this situation would occur.Why RTC_WakeUpCmd can fail?Thanks,Gabriel
Hi everyone, I'm using the STM8L152R8 Nucleo board and trying to get the RTC running on the LSE clock. It works but only inconsistenly, about 2/3 runs error out in the RTC_EnterInitMode function of the SPL the below line. RTC_EnterInitMode is called ...
Posted on July 11, 2018 at 17:34Hello everyone,Why does the STM8CubeMX prohibit the clocking of the RTC with a frequency of less than 1 MHz, not allowing to use of an LSE? I want made a watch!Thanks in advance.#lsi #rtc #stm8cubemx #clock-configurat...
Posted on April 21, 2018 at 14:35Hello everyone,Very much I ask to respond who knows. Whether methods are applied of providing increased reliability of real-time timers, for example redundant coding or majority calculations. And what are the values ...
Posted on November 19, 2015 at 23:22I'm working on some code to set the RTC alarm, and I've gone through all the resources I can find on how to set this up correctly, but it's just not working. If you could take a look and see if I've missed anythin...
Posted on February 28, 2015 at 19:25I've been called to help support a project using an STM8. They are having problems with RTC clock drift, a couple of seconds a day, and showed me section 24.3.8/9 in the RM0031 datasheet. I found the document AN...
