Improvement for the definitions of factory calibration values

Inspired from a beginner issues in this topic, I noticed a possible improvements. Let's take an example from a stm32f767xx.h definition file:#define VREFINT_CAL_ADDR_CMSIS ((uint16_t*) (0x1FF0F44A))The first improvement is to add a ...

STM32F407 Fatfs Causing the Time-based source to be in Hung State.

I am using the Fatfs to mount the SD Card. As soon as f_mount is called it puts the ticks in hang up state causing the HAL_Delay to be in infinite loop resulting in device hang up.I am using the STM32F407-Dicovery BoardFor SD Card I am using the SPI1...

Seeing an issue with USB interrupts on STM32H742 only on Endpoint 1 USB Enumeration works fine. I am seeing HAL_PCD_DataOutStageCallback for endpoint 0 but not HAL_PCD_DataOutStageCallback for endpoint 1. Any ideas what I might be missing?

Initialization sequence:hpcd_USB_OTG_FS.Instance = USB_OTG_FS; hpcd_USB_OTG_FS.Init.dev_endpoints = 9; hpcd_USB_OTG_FS.Init.speed = PCD_SPEED_FULL; hpcd_USB_OTG_FS.Init.dma_enable = DISABLE; hpcd_USB_OTG_FS.Init.phy_itface = PCD_PHY_EMBEDDED;...

Hiii there, Recently , I am working on STM32 Nucleo-H745zi-q and i am not able to configure the ethernet protocol in same. Whenever i try to ping it , it not acknowledge at all. Please help me with same. Thank You

STM32F4 Ethernet interrupt not triggering for up to 1500 ms after random period of time.

Hey,After debugging for a long time I still haven't been able to find the cause of ethernet interrupt not triggering for up to 1500 ms.What I'm doing is opening a socket on my STM32F4 + LAN8742A. I am running a script that sends an "heartbeat" every ...

NUCLEO-STM32F767ZI and STM32 CUBE IDE

Good day,I have a NUCLEO-STM32F767ZI and a problem with the STM32 CUBE IDE. When I create a project in version 1.5.1 with ETH, FreeRTOS and LWIP everything works fine. When I create the same thing in the latest version, the generated code falls into ...

How to combine HAL_I2SEx_TransmitReceive_DMA with arm_biquad_cascade_df1_f32? Due to data Receive as uint16_t but the arm filter input is float32_t.

Why is remapping necessary for jumping to bootloader?

When jumping to bootloader from software for devices such as the stm32l4, why is it necessary to remap system memory to address 0x0000 0000 in address space by calling __HAL_SYSCFG_REMAPMEMORY_SYSTEMFLASH? On the contrary, the stm32H7 doesn't require...
