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...
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...
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...
I’m working on a project that requires bidirectional communication between daisy-chained STM32F103C bluepill boards and an ESP8266. I’m using a master-slave architecture and UART for initial testing and prototyping. The chain has 3–6 STM32 boards. Ri...
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...
Hello everyone,I'm working on a custom board with an STM32H563 and using CubeMX, HAL, and ThreadX.I am trying to receive variable-length UART data via DMA using HAL_UARTEx_ReceiveToIdle_DMA(). My problem is that the HAL_UARTEx_RxEventCallback never t...
Hello, I have designed a custom PCB using STM32N657I0HxQ and W25Q32JWZPIQ NOR flash. I am following the STM32N6 FSBL Load & Run tutorial https://community.st.com/t5/stm32-mcus/how-to-create-an-stm32n6-fsbl-load-and-run/ta-p/768206 , but have troub...
Hi, Im planning on using STM32H747BGT6 in LDO mode only and no USB interfaces will be used. What should I do with SMPS pins (VSSSMPS, VLXSMPS, VDDSMPS, VFBSMPS) and USB supply pins (VDD50_USB and VDD33_USB)? The datasheet nor the application note don...
