Dear STM32 Community, We believe that the example projects provided for the STM32Cube embedded software are a valuable resource when developing projects. We would like to better understand how developers use these examples in their workflow and e...
I have USB2 OTG high speed port1 working in "device mode" on the STM32N6570-DK board. I need to transfer an image file (around 10 MBytes in size) from the external PSRAM IC (APS256XXN-OBR-BG Hexadeca‑SPI PSRAM) to external PC via a bulk CDC IN endpo...
Hello STM32 Community,I am working on the STM32F769I-DISCO board and would like to implement UDP communication using LwIP with FreeRTOS.I have already downloaded the STM32F7 series example projects, and I see that the LwIP_HTTP_Server_Socket_RTOS exa...
Hi. I have a problem while using lwip and freertos. The board is based on stm32h743vih. The mpu configuration is done correctly i think. My problem is after i start udp server and start to send data with udp, everything is ok, but after a while i wil...
Hi, I'm not able to find any DMA available with CAN peripheral in STM32G4. After going deep search I found there's no such native DMA request available for CAN peripherals. So, I want to know is it true that STM32 controllers don't come with DMA with...
Hi,I would like to consult the USB HID GetReport feature.The issue is that the printout data from MCU log is different from bus hound displayed result.Bus hound is trial version, the data length indeed is 16.This is the log I set to printout from USB...
Hello,I would like to use the X-CUBE-CRYPTOLIB to calculate a SHA256 with a key, i'm using STM32CubeIDE 1.18.0 for an STM32u083 microcontroller, STM32CubeExpansion_Crypto_V4.2.0.The issue I have is the first time I call cmox_mac_compute the wrong res...
Hi, I am developing firmware for an STM32H747 with Ethernet connected via RMII to a LAN8742 PHY. The project uses lwIP and FreeRTOS. UDP communication works fine when sending data, but when receiving UDP packets, the system crashes after some rundom ...
Hi, I recently started a project using the STM32H747BIT MCU and I’m configuring ThreadX v6.4.2 as the RTOS. I followed the usual steps to integrate ThreadX into my system. I decided to use the ThreadX source from the GitHub repository instead of the ...
I am using the STM32H523 microcontroller with I3C function and a system clock of 250MHz. I am configuring LL-I3C_SetPeriodClockHighI3C (I3C1,0x0D) based on the LL library;LL_I3C_SetPeriodClockLowPP(I3C1,0x0D);LL_I3C_SetPeriodClockLowOD(I3C1,0x0D);At ...
Hello Microsoft Community,I’m currently working on implementing a file system using FileX and LevelX on external NOR Flash (IS25LP064D) connected to the STM32U585AII6Q board.Flash Memory Specifications:Sector Size: 4 KBBlock Size: 32 KB / 64 KBTotal ...
