WebAug 31, 2024 · The RTC keeps ticking in the background and once the frozen registers are read out, the RTC fill the registers in with their actual current time value. Without the shadow registers, we're reading from a permanently updating register value. (So also this won't work because the HAL assumes shadow registers are on in the function) WebDec 5, 2024 · STM32 RTC milliseconds setting Posted on June 07, 2024 at 03:50 Hello, I'm using the STM32 H753 Evaluation board, and trying to set the milliseconds by using HAL_RTC_SetTime function. However, the HAL_RTC_SetTime function does not change the milliseconds (subseconds) value.
WebMar 29, 2016 · The STM32F4's RTC has 20 x 32-bit backup registers RTC_BKP_DR0 to RTC_BKP_DR19, which are maintained while in a power-off state if Vbat is supplied from a coin-cell battery or other. There is no support in mbed's libraries for reading/writing from them, but again we can use STM HAL library calls instead. WebNov 16, 2024 · The STM32H743AI microcontroller will be used as the target device. It uses an Arm Cortex-M7 core that embeds the MPU. 4.

WebAug 19, 2024 · What you are missing are the wakeup counters (below wakeup clock in your screen). That is - the RTC counts the clock pulses (say coming from CK_SPRE) and only wakes you up when the count reaches the value set in wakeup counter. Assuming CK_SPRE is at 1 Hz this gives you a maximum wakeup period of 36 hours (as stated in the reference … WebJul 9, 2014 · RTC peripheral has 2 between independent alarm sources which can trigger an interrupt once a week or once a month according to its settings.
