STM32L432 LPTIM prescaler behaviour
I have a NUCLEO-L432KC that I am trying to configure such that a LPTIM interrupt fires at a set time period in the future. To simplify calculations, the future time is 2048 low frequency clock ticks away (62.5 ms).I can achieve this with relative sim...
Resolved! SDIO, USB Mass Storage, and Mac
Hi! I am trying to learn about interfacing with an stm32f405 as a USB Mass Storage Device. My (homemade) development board has an onboard microSD card slot, and so I would like to present the card as my mass storage. I'm running into some problems wi...
Resolved! Circular dependency in HAL driver for STM32H5.
Hi!I have a project that will not compile due to "error: 'HAL_StatusTypeDef' does not name a type".The project uses STM32H563 and includes file stm32h5xx_hal_conf.h.The HAL_RCC_MODULE_ENABLED and HAL_GPIO_MODULE_ENABLED are defined.When looking into ...
Resolved! W25Q32 SPI FLASH ON STM32U083MCT6: f_mount() returns FR_NO_FILESYSTEM
I'm using STM32U083C-DK which contains STM32U083MCT6 MCU. I want to use W25Q32 NOR Flash using standard SPI protocol. For implementing the file system, for my MCU -> Middleware doesn't have FATFS instead it has FileX, LevelX and ThreadX. I couldn't f...
Resolved! Issue Increasing USBD_VIDEO_EPIN_HS_MPS for UVC Implementation on STM32U5G9J-DK2
Hello,I am facing an issue while implementing USB UVC (Uncompressed) on the STM32U5G9J-DK2 board.The setup works fine with USBD_VIDEO_EPIN_HS_MPS set to 1400U, and I can achieve image output. However, increasing the endpoint packet size beyond 1400U ...
fx_file_open does not work from a different thread
I have an application using STM32L475, threadx, filex.Functions in the filex API work well when called from a specific thread: the same thread that initialized and mounted the file system. If I call the same functions from a different thread, the sys...
STM32 FATFS with SPI FLASH
I am trying to interface a SPI flash from Winbond (W25Q64JV) with FATFSI have no previous experience with FATFS.I initialize FATFS in CubeMX with the option "used-defined" and modified the MAXIMUM and MINIMUM Sector Size to 4096, as it is the smalles...
How to turn release target into debug target (STM32CubeIDE)
Hi All,By mistake the default debug target got deleted and our development/testing target got created using the release target. I was looking at what are the exact options in which the debug and release target differs so I can create the debug target...
STM32F767ZI with LWIP and FREERTOS not working
I am using an STM32F767ZI dev board and trying to set it up as a TCP Server. After initializing LWIP and FREERTOS, I am having problems with pinging the board. After checking my gateway, it seems that the gateway is able to sendt packets to the stm32...
