STM32CubeMX 5.6.1 , Atollic TrueStudio 9.3.0 , MCU is a STM32L053 with VDD wired to a coin cell. LSE is connected to a watch crystal.The RTC works fine. Going into standby mode works fine. Waking up from standby mode works fine. Checking and resettin...
Hello,I'm using TIM2 on STM32H743 (Nucleo, rev Y, Keil 5.31).Just before setting the bit TIM_CR1_EN the setting of the timer is the following:DIER : bit UIE setPSC: expected value (0x4E1F)ARR expected value (0x4E20). it is almost the same as PSC but ...
I have a little problem with external mode and I didn't know if it's nortmal or just a lack of setting from myself. I use F429 with 5.4 version and R2018bWhen I run my soft on STM32, the time is passing good (I see it with my CAN_message coming from ...
I am trying to understand how to setup the microcontroller (STM32F030 in this case) to use external oscillator. I am using blinking LED as a test to see if the code is running. To setup the HSE I did following:selected Crystal/Ceramic Resonator in Hi...
Strange behavior of STM32H743. It continuously reset every few seconds.I check reset reason with this part of code after system startup:if (__HAL_RCC_GET_FLAG(RCC_FLAG_IWDG1RST)) { _PRINTF("RESET_CAUSE_INDEPENDENT_WATCHDOG_RESET\n"); } else...
Greetings,I want to save a variable just before power down. There is PVD feature but it is not supported in STM32F030R8... Is there any other work around for the same ?
Hi,I am asking for some sound technical help on the STM32F769NI BootloaderI am using an STM32F769NI MCU and wish to update the firmware using STs' Bootloader mode via the UART.I am running into problems that none of the UARTs on Pins PA9/PA10, PB10/P...
Hello,I'm using the NUCLEO-F722ZE EVB.Page 155 of the datasheet describes the ADCs characteristics: https://www.st.com/resource/en/datasheet/stm32f722ze.pdfFrom the NUCLEO-F722ZE schematics I see that VDDA as well as VREF+ are 3.3V. VREF- is zero vol...
I'm trying to test the window watchdog timer but when I'm calling HAL_WWDG_Init(), it redirects to reset handler and whole system restarts. Below is my code, I'm showing here only important lines./******************************************/WWDG_Ha...
