Resolved! Switch off VREFBUF on STM32U5
Is it possible to switch VREFBUF clock off after configuration for power save? So the clock is off and the buffer is providing Vref.In DS there is no mention about it (e.g OPAMP has this note).

STM32H5 SPI DMA LL Transfer Timing Issue
Hi All,I’m new to using the STM32H563 solution. To send SPI data using DMA, I referred to the sample code from the SPI DMA sample of the H533RE project.I'm not sure when exactly the SPI is start to transfer the data by DMA.The following is a part of ...
STM32G071 ADC sequencer in not fully configurable mode and ADC channels set run-time changing
On my custom board based on the STM32G071CBT6 mcu I use ADC multichannel DMA conversions, DMA continuous requests, triggered by TIMER2 out event and driven with HAL library (STM32G0 firmware package V1.6.2). I get ADC conversion results by the conver...
Updating firmware via IO-Link
Hello,I have a question regarding doing a firmware update via the USART-pins and IO-Link.Would it be possible to use a IO-link master module to sent an update to the L6362A which translates it to 3.3V UART for the STM32G0B1KEU6 we are using in our cu...

Resolved! STM32U595 used PA12 and PA11 as INPUT gpios,can't get the HIGH level
Hi,I used PA12 & PA11 as input gpios(pull-up) in STM32U595VJT6Q ,read the pins are always '0'.The IOs connected NOTHING.I reference RM0456 : I config USBPWREN and VDD11USBDIS bits used the HAL functions before GPIO_Init():HAL_PWREx_EnableUSBHSTrance...
OCTOSPI line idle level - Weird behaviour
Hi, Community,I'm trying to understand the OCTOSPI peripheral on my STM32L4P5. I'm new to STM32, but old in embedded. Particularly, I need to know/affect the idle level of the data line of the OCTOSPI. I thought that the last transmitted bit would re...
STM32 Phase Vocoder Algorithm
Hi! I'm looking to implement a phase vocoder algorithm on an STM32F4/STM32F7 and I was wondering if anyone has already done this and can provide suitable resources?Thanks!
Resolved! UART TX and RX pin issue
Hello,I am using "NUCLEO-H743Zi2" eval board. I am using it for UART communication. I had configured UART4 in it as following;PA0 as UART4_TXPA1 as UART4_RXWhen I tried to transmit, it is not transmitting more than 2 bytes. While receiving, it is not...
I2C Slave Receive in DMA mode on STM32U575 series
Hi,I'm attempting to set up an STM32U575 as an I2C slave. (The master is a F301)My problem is that the slave only receives one byte, and then proceeds to disregard all of the following data.I have set up a switch that turns on an RGB LED, depending o...
