Is their any possibilty to use CDC and DFU due to the same USB Port, by switching it by software? And is their any example for it? I tried several things but couldn't find any solution. The configuration at CubeMX Just allows one Class for USB_DEVICE...
I am writing a STM32H745 app, to connect to an external 3rd party device with a web POST API, via onboard LANxxxx IC ethernet.The data transactions are reasonably standard web POST requests, with the caveat, that the inbound request may arrive in sev...
Hi everyone, I have a problem with placing data in RAM from DMA with H7. I have a custom bootloader that then jumps to the application that uses ADC, + DMA, TIM + DMA etc.. I ran the classic __attribute__((section(".D1buffer"),used)) and modified it ...
I am using a NUCLEO-G071RB dev board with a X-NUCLEO-SNK1M1 expansion board to create a USB PD sink application. I downloaded the project files from this GitHub repo x-cube-tcpp/Projects/NUCLEO-G071RB/Applications/USB_PD /SNK1M1_Sink/ and only change...
Excuse me, I'd like to seek advice from experienced members.I'm using the STM32F429IGT6 microcontroller in an environment with FreeRTOS and LwIP. I'm attempting to create a TCP Socket (or netconn) server using the LAN8720A network chip to achieve one...
I've managed to get tcp/ip working just fine on the NUCLEO-429ZI board, but I'm unable to make similar code work on the 407ZET6 chip, despite using what I believe to be a nearly identical circuit with the LA8742A chip. I suspected it had something t...
I have a project created with TouchGFX for STM32CubeIDE.All in latest versions and it works. The firmware pack has a support for the WM8994 audio chip as BSP driver. I lost like a month of my work trying to figure out why the driver fails randomly to...
Hi,I'm working on STM32G0B0RE custom device. I have ported SBSFU through USB CDC. I'm able to program SBSFU and application. The application is working as expected but when I try to upgrade application it fails to rewrite the application header in th...
I'd like to activate the user USB on the NUCLO.H753ZI board, as a USB device for serial emulation (CDC)I use CUBE generated code (basic demo setup for this CPU), the ST-Link USB works and I can debug. I may add, that I have USB working with Cube-code...
Hi all,I have been trying to get I2C DMA working on an STM32H723 for a few days now. It works perfectly when using blocking mode (using HAL_I2C_Mem_Read), but when I try to use HAL_I2C_Mem_Read_DMA it returns success, but doesn't actually do the read...
