Hello, I bought STM32H743XIH6 board and first tried to program it with FTDI programmer and STM32CubeProgrammer. It looks like the serial interface detects the board correctly as I can see it in the STM32CubeProgrammer but fails at a read attempt of 0...
Hi, I have a question about supplying power to DSI interface on STM32H747BGT6 (208 LGFP package).RM0399 says, "The DSI interface is supplied from a dedicated VDD12DSI supply that can be provided eitherby the integrated DSI regulator or by an external...
Hi everyone.I'm trying to send more than 256 bytes of data from the host to the STM32 using USB CDC VCP, and I don't know why VCP won't accept more than 64 bytes of data. My project is already halfway done. If I switch to the USB bulk method, do I ha...
Project Name: custom surveillance droneCase Description:Hi STMicroelectronics Support Team,My name is Shuvadeep Mazumder, and I am the Founder & CEO of Model of Engineering (https://modelofengineering.com). I am currently leading the development of a...
Hello,I’m developing a USB composite device on STM32 that combines RNDIS and CDC interfaces.The device works perfectly the first time it’s connected to a Windows 10 PC — both RNDIS and CDC functions operate normally.However, after I reset the MCU or ...
I tried to follow this tutorial: How to build an AI application from scratch on the... - STMicroelectronics Community , could not figure out how to enable NPU RIF, so i skipped it. I tried to debug using the FSBL main.c, the blue led did turn on, but...
Hi i am working with LTDC with STM32F429ZI Discovery -1 board with onboard LCD. I really want to drive a external LCD RGB display without An ic controller by utilising the Internal LTDC hardware inside the MCU . Can you please give some support on th...
I've searched and not found anything describing this behaviour (on the internet or this forum, which I've found to be an incredible resource so far - thank you).I have a configuration where I go into STOP, exit out of STOP via EXTI, start TIM1, allow...
Hi,I have a DMA2D issue with a STM32N6 Nucleo-144 board. I can use the DMA2D to blend two framebuffers if the inputs are in the AXISRAM1. However, when one of the framebuffers is in AXISRAM3 (NPU RAM), the DMA2D doesn't copy from the relevant framebu...
I just spent some time debugging a fundamental compatibility issue between an MPU and its RAM, and I wanted to share what I learned to save others the same headache.I was looking at using the STM32MP657 (a powerful Cortex-A7 MPU) and almost made a cr...
