This article provides guidelines on how to use the LPBAM feature in the STM32U5 series to allow peripherals to be autonomous and optimize the power consumption in STOP2 mode.The LPBAM stands for low-power background autonomous mode. It is an operatin...

Hello @Eddiie, Please refer to RM0038, USART section, the STM32L152 does not support waking up from stop mode via UART directly, a workaround is to configure an EXTI line for the USART Rx pin, which will allow you to wake up the MCU from low power m...

Hello @raisa_razak, I think you are not properly handling the interrupt. When the external interrupt occurs, you are starting the timer and incrementing the variable, but you are not resetting the seconds variable to 0. This means that (seconds ==...

Hello @VOANHVU According to UM3184, The expansion board can be connected to either a NUCLEO-F401RE or a NUCLEO-G431RB development board. Theoretically, the NUCLEO-G474RE and X-NUCLEO-OUT01A2 both follow the Arduino Uno V3 connectivity standard (that...

Hello @Ans, I checked your code and it looks ok, to make sure FreeRTOS has already temporarily suspended its tick interrupt, in Freertos.c, in PreSleepProcessing macro: add SysTick->CTRL &= ~SysTick_CTRL_TICKINT_Msk as following void PreSleepPr...
