Note: AN3371 Application note Using the hardware real-time clock (RTC) in STM32 F0, F2, F3, F4 and L1 series of MCUs Introduction A real-time clock (RTC) is a computer clock that keeps track of the current time. Although RTCs are often used in personal computers, servers and embedded...

AN3371 应用笔记 在 STM32 F0, F2, F3, F4 和 L1 系列 MCU 中使用硬件实时时钟 (RTC) 注: 前言 实时时钟 (RTC) 是记录当前时间的计算机时钟. RTC 不仅应用于个人计算机,服务器和嵌 入式系统,几乎所有需要准确计时的电子设备也都会使用.支持 RTC...
Returns an unsigned 16-bit integer value stored on the backup register identified by the givenindex.indexparameter is unsigned 8-bit integer value as index of backup registers. Index value is 1-10 for low-density and medium-density devices of STM32F1xx family MCU, or 1-42 for high-density...

Posted on October 14, 2015 at 00:22 Hello, I am trying to get my STM32l053 to wake up from stop mode using the RTC wake up timer (using CubeMX).
The GNSS receiver is configured to send the current time over serial, and on the next rising edge of the timepulse signal the RTC is set to (time+1s). The STM32 RTC only counts in milliseconds, so there is always up to +/-1ms of jitter. (Future work may include using a GPT to ...
Second problem is it goes into a loop where MCU goes to sleep and wake up on RTC interrupt. This is like continuous loop and RTOS does not resume the tasks I call from main which is just to blink LED's.I took reference of web link mentioned on previous post by Richard and STM32l...
The STM32L496VG has a full range of peripherals for a high performance IoT endpoint including a real-time clock (RTC) with calendar, three 5 megasample per second (MSPS) ADCs, a two-channel digital-to-analog converter (DAC), two controller area network (CAN) interfaces, and four I2C...
The STM32F407VGT6 micro- controller has three 12-bit ADCs, two digital to analog converters (DACs), a low-power real-time clock (RTC), two advanced-control timers, eight general-purpose timers, two basic timers, two watchdog timers, a SysTick timer, a true random number generator (RNG...
