Problem: RTC Wakeup interrupt is not working on STM32L4 after calling the HAL_RTCEx_SetWakeUpTimer_IT.Cause:A preprocessor macro check rules out a call to the __HAL_RTC_WAKEUP_EXTI_ENABLE_IT for uC other than STM32L412xx / STM32L422xx in the file stm...
Hi folks, I'm working on STM32H753 mcu using USB2 (Full Speed mode) in DEVICE MODE, I must send the MCU in stop mode and wake it up when a message on USB is detected. I can't do it and I don't find any information. Can someone help me? thaks in advan...
Posted on April 27, 2018 at 20:30My project uses STM32CubeMX generated code for USB FS Device in MSC class. I am using Windows USB Device Viewer trying to analyze what's going wrong.1. The device connects but curiously there are mentions of 'device ...
Posted on March 20, 2018 at 14:35Hi everybody,i'm tryng to wake up MCU STM32L051T6 from stop mode using a GPIO pin. The pin is PB4 on Rising edge.This is the code:void stopMode(void){ DBGMCU -> CR |= DBGMCU_CR_DBG_STOP;RCC -> APB1ENR |= RCC_APB1ENR_...
Posted on February 27, 2018 at 23:57I'm trying to put the Nucleo-152re dev board into stop-mode, when there are no tasks running. It successfully enters the stop mode(i think) but the current consumption is 150uA. I have read in the manual that it s...
Posted on December 20, 2017 at 13:52Good afternoon everyone,I'm working on a ultra low power FreeRTOS application, in which I need to enter and exit continously the STOP2 mode from my MCU, STM32L476RG. The problem is that I need to wake up working a...
Posted on November 07, 2017 at 17:43Hello,I want to use the BAM mode, and more specifically, D1/D2 in DSTANDBY, while D3 is in RUN mode. In this mode i want to have ADC3 sampling 3 channels, and transfer the results to RAM using BDMA. I am using LPT...
Posted on August 22, 2017 at 18:55I'm working on a low power mode for my project using an STM32L476ZG to enter when no tasks are currently running, I want to wakeup with either an interrupt controlled by the RTC (connected to an external crystal LSE...
Posted on July 27, 2017 at 09:55I have a problem with STM32F756 USB CDC (HS with FS PHY) device and core sleeping. I isolated all other code and left only the USB driver and main loop calling WFI instruction. If there is no call to WFI, USB is worki...
Posted on July 06, 2017 at 15:40Hello,I am working on Stm32l073 series controller. I have small question regarding the deep sleep and exit from deepsleep modes when device is not plugged to PC i must make the device go to sleep. As the Block Diagram...
