Hi,I am not able to output per I2S properly.1. I changed from a properly working driver for STM32F407 to this STM32H7A3VGTI had to learn, that the master clock is different as for the 407; here is always running (?) and the DMA did not work properly ...
Hi everyone!I'm having trouble in measuring the VBAT through ADC. I'm using 3.3V on aNUCLEO_476 board to connect to VBAT and when I measure VBAT through ADC,I cannot obtain the value of the VBATHere's my code:void MX_ADC1_Init(void) { /* USER CODE...
I'm a USB newbie and am trying to use the STM32F411CEU6 as a USB mic. I'm currently using FreeRTOS (cmsisV1) and the Cubemax USB library. My device currently enumerates normally, but when the host sends a URB_ISOCHRONOUS_IN request, my MCU won't hand...
Hello,meanwhile i tried for ethernet udp several examples. But either these could not be importedin STMCubeIDE 1.19.0 or were based on RTOS.Did any know or have an example for it?Thank you!Best regards, HiST
I’m encountering an issue with XSPI1 in my application. I boot the application via XSPI2 in an LRUN configuration, and this part works perfectly. However, within the application, I need to use XSPI1 to write data to a different flash.During MX_XSPI1...
Hello,I am trying to set up a UPD communication with a nucleo-H755ZI-Q board.Now I have the effect, that the lwip stack sends out an arp request for its own IP address.I double-checked the IP address and destination address to make sure they were co...
Hi all,I'm currently working on a project using a STM32H753 in combination with the Azure RTOS UsbX to create a composite class USB device (CDC ACM + MSC). As a starting point for the MSC support, I'm using this STM github example:https://github.com/...
Dear STMicroelectronics Support Team,I previously submitted a request on [ Auguest 26, 2025] (case #[00242096]) and have not received a reply.I am evaluating STM32 MCUs for an LwM2M client implementation and need clarification on ST’s official suppor...
HiI have implemented TCP/IP with LWIP, but after enabling the freeRTOS, I'm facing lot of issues, ping is not happening, flash overflow errors , internal flash is very less need to use external flash(how to configure?). Mainly I need to enable freeRT...
I'm already achieved a USBX-MSC class, and also a FileX in MCU local.I know that using two file systems at the same time is not recommended, but still have some questions. 1. I implement the ux_deveice_msc.c as followed. Use PC-Windows to create a f...
