Hello all, I disabled the M4 core based on the tutorial by ST Employee mEALLEm, I pressed Apply, saw the option byte successfully programmed notification, but I have been waiting for MCU disconnect notification for 20 minutes now. The LD4 keeps blink...
For community awareness:Unless otherwise stated, STM32 GPIOs do not have partial-power-down / Ioff / back-drive protection.Example: If VDD=0V (or VDD unpowered) and a GPIO is driven with 3.3V, then excessive current may flow into the GPIO.This includ...
We are currently working on a project using the STM32H750IBT6 microcontroller interfaced with a single-bank Quad SPI NOR Flash (MT25QL512ABB) on our custom board. The QSPI interface is operational.However, we are facing an issue with the external loa...
i use stm32h750 as a decoder to translate use audio data into i2s 16bits 48khz data.however, when i use usb_otg_fs, everything works properly,but when i use the same configration and only switch to usb_otg_hs,some problem has occured. i use usb3300-e...
Hello,maybe this is bit off-topic, but does anybody know if it is possible to suspend an ERASE operation and write to another (previously erased) sector?I want to save a page in flash in case of a power outage and want to interrupt a probably ongoing...
Hello, According to the STM32L496 reference manual, the DAC should be disabled before entering STOP2 mode, which implies that it doesn’t operate in STOP2.However, in STM32CubeMX there is a configuration option for DAC output — external pin, on-chip p...
Hi!I’m currently building an application where I need to periodically wake up my NUCLEO-U575ZI-Q from Standby mode using RTC alarms. I’m aware of the Wake-Up Timers, but I’ve been specifically asked to use alarms. This will be integrated into a FreeR...
Hi, am new to STM32 and i am trying to configurate my Nucleo but i don't understand my problem i am trying to setup a basic blink code with the basic structure (serial port communication with putty , debugger stlinkv3 and communication between cores ...
Hi all,I’m currently working on a wireless mesh network project using the S2868A2 expansion board with the NUCLEO-U083RC, operating in the 868 MHz ISM band.This system is designed to be low-power, which is why I’ve selected the Sniff Mode (LDCR) feat...
Hello everyone,I am doing a project of sampling a PWM signal and reproduce it dynamically using the HRTIM. The following code:uint16_t oldPer = 0, oldDur = 0, update = 0;uint16_t newPeriod = 0;uint16_t newDuration = 0; void HAL_TIM_IC_CaptureCallback...
