Resolved! STM32U535 'Q' SMPS usage
Because there appear to be little/no stock of the STM32U535CEU (QFN Version) I'm left with a dilemma of whether to use the built in SMPS. Some documentation in another post describes how to connect up when not using it but how do you switch between ...
Resolved! How to wake-up on time in time with RTC ?
Hi eveyone,I have a problem with RTC wake up. I use LSE 32.768kHz.I run example from manufacturer to wake up MCU from Stand by mode very 1min, 2mins. Everything work okay.But, When I put delay 10s and HAL_PWR_EnterSTANDBYMode(); into while(1). Everyt...
Resolved! Subject: STM32H753ZI cannot control PC02 as GPIO or SPI2_MISO functionality.
Hi expert, our project is currently in the development stage. We are using the NUCLEO-H753ZI Development Kit for firmware development while awaiting the arrival of our custom board from the manufacturer. The dev-kit employs the STM32H753ZI (LQFP144),...
Resolved! STM32F746-Disco, how do I enable ethernet and ping the kit?
HiWe are trying to use the f746 disco kit as a udp server that writes what it receives to an SD card. The kit is currently connected directly to a PC with ethernet and usb. As this is our first stm project, we tried following several tutorials that a...
Resolved! STM32F103: Using DMA1 Channel 3 for SPI1_TX and USART3_RX same time
I'm currently working on a project using an STM32F103RET microcontroller. I need to use SPI1 to write log data to a flash chip at an rate of 64 bytes every 20 milliseconds, and use USART3 monitoring external communication, receiving an average of 30 ...

Hi,I'm developing a product based on ST controller.Regards,
Sensorless bldc motor controller six step trapezoidal control
I have implemented a sensorless, six-step trapezoidal control with feed-back as zero crossing detection using back emf with the help of ADC on the nucleo-G431 board.The BLDC motor is A2212/13T, 1000 kV.Without a propellor, the motor is spinning, and ...
Resolved! stm32l431rct6: SD detect pin question
Sorry, are there has a pin call or used for SD_detect in Stm32l431rct6? I can not find in STM32L431xx Datasheet - production data. These has no mention.I do not know which pin(SD-Detect)should i choose for GPIO_Input of the FATS.
Resolved! On STM32C0, is SRAM preserved in Sleep mode if RCC_AHBSMENR.SRAMSMEN=0?
Hello,In STM32C0 RM0490, section 5.4.16, the RCC_AHBSMENR describes the bit SRAMSMEN which can be used to disable the SRAM clock during Sleep mode to save power. We will be using the STM32C0 in a low-power application and I was wondering if the SRAM...
