Hi everyone, I am trying to use LPTIM1 and I2C3 to read the values of a sensor's register every 1 second and save them into a data buffer while in Stop2 mode. What I would like to know is if it is possible to store data sampled at a given frequency ...

Hi @Displaid23,Yes, I recently found a way to solve this issue. I implemented 2 queues: the first one handles I2C Data Reception and the second one manages a DMA memory-to-memory transfer that moves the received data into a buffer located in SRAM4. T...

Hi everyone! I stumbled upon this GitHub repo (https://github.com/BlaineMoon30/stm32u575_nucleo_mw_usb_device_cdc/tree/master) containing a working project that implements USB-CDC transmission with NUCLEO-u575ZI-Q. The project features a data loopbac...

Hi, I found out that the error at the line "((USBD_CDC_ItfTypeDef *)pdev->pUserData[pdev->classId])->Init();" was due to the fact that the TIM Base generation in interrupt mode was called twice (both in the CDC_Itf_Init() and in the TIM_Config() func...

Hi!Thank you for your quick answer. However, I have already done the modification you suggested, and it still doesn't work. As regards your question, on the NUCLEO board I am using the USB-C connector (CN15) and not the STLINK-V3 to implement the USB...
