Impedance control for high speed SPI
Hello,We are a company making medical air transport containers. We use ST micro-controllers (STM32L562ZET6Q) to track, monitor and control our containers around the world.We are having issues with signal integrity between our micro-controller and our...
Fastest memory-to-memory (actually to/from GPIO) DMA using STM32H562VI
I am new to this forum and to STM32CubeIDE.I am working with a NUCLEO-H563ZI board.Where can I find how to decide the best Timer to use for my DMA?The top priority for my project is to set up DMA to do 3 things simultaneously as fast as possible for ...
Resolved! STM32U599NJH6Q
Is this device in the witness protection program? Anglia cannot export the device outside the UK. Contacts for ST office in Canada are not listed. Good job. DK / Mouser list prices at 2-3x those on Anglia with 0 stock and ETA of the end of this year....
STM32L052T6Yx usb(virtual port com) to pc
I want use this mcu STM32L052T6Yx to communicate via usb (virtual port com ) whit pc (whith linux system operativ).THE power supply of mcu is 3.3v, can I problems if i directly connect PA11 PA12 PIN to the pc usb (common ground)? , moreover on pin...
Combined UAC + HID functionality with STM32L452RE
Hello,I am new to the forums here! Can STM32L452RE support a combination class of HID and USB Audio Class over USB 2.0 Fullspeed?Ideally, I'd like to read and send microphone data (or any sensor data for that matter) connected to STM32L452RE over USB...
SPI data size reducuction to 1-bit
I have a rather strange request, but I am communicating to a Digital Potentiometer (AD5227) over SPI. The chip has 64 available positions, but can only increment or decremement its position by 1 for each clock cycle. To increment by 1, a 1 is place...
STM32F 407 &&& 2 USB MASS STORAGE DEVICE
Good evening guys, I have an educational project for the USB protocol on the stm23f407 discovery board I made the project on two sensors and each sensor is written to a flash drive on a separate usb_otg_host port because the stm32f407 discovery board...
Resolved! STM32H723 ADC read stuck (using LL libraries)
Hello,In my project I just sometimes need to read ADC values. I figure I could simply connect two of my signals to ADC1 and ADC2 respectively.What it strange that it does sometimes working, but sometimes it is stuck at constant value ( maybe first re...
CM7 goes to infinite loop at 0xa05f0001 when enter/exit D1Stop mode on STM32H755(or STM32H745)
Hi support,I am trying to have STM32H755 boots simultaneously with following use case and seeing that CM7encounter an infinite loop execution at 0xa05f0001 for some reason. Could someone help me tounderstand why this is happening and what is wrong wi...
