Ask questions and find answers on STM32Cube packages, including HAL, LL and middleware, and expansion software.
Dear STM32 Community, We believe that the example projects provided for the STM32Cube embedded software are a valuable resource when developing projects. We would like to better understand how developers use these examples in their workflow and e...
I'm working on entering and exiting low power run mode at runtime on Zephyr rtos. I can't find a way to change clock frequency to 2MHz (required by LPR) and back to 80MHz using zephyr features at runtime. Is there any api to achieve this, or some si...
Hi Team, I made a custom board using STM32F769BIT microcontroller using with the DP83867 PHY in MII mode, but I am not able to ping it. What could be the possible reasons? I did Memory configurations for TxDecrip, RxDecrip, LwipHeap like this. .lwi...
Interrupts not in proper peripherals:- WWDG is placed in I2C2,- TIM8_CC is in peripheral TIM1,- LPTIM1 is in LPUART1,- USB_HP, USB_HPLP & USBWakeUP are in EXTI,- CRS is in the EXTI as well.
In stm32u5xx_hal_flash_ex.c, version 1.6.2, FLASH_OB_GetUser() is defined as:/** * @brief Return the FLASH User Option Byte value. * @retval The FLASH User Option Bytes values. * The return value can be a combination of @ref FLASH_OB_USER_BOR_LEVEL, ...
Hi ST community,I am using the B-L4S5I-IOT01A board to record 3 sec of 16 kHz audio using DFSDM + DMA, and then transmit it offline via UART (after recording is complete). Since two MP34DT01-M microphones are connected to DFSDM Channel 2, I configure...
Hi, I am having issues with threadX tx_byte_allocate throwing a hard fault exception. This only happens after some time of byte allocate and release. There are still plenty of available bytes according to the pool. But somehow in _tx_byte_pool_searc...
I'm trying to implement a USB touchscreen on a NUCLEO F446ZE. I'm making a full-speed device using ST's USB library (Custom HID class) and I'm testing it with on a Windows 10 host. The first contact registers, but when I try to press another, it doe...
I am currently experimenting with STM32F030RCTX and STM32F030CCTX devices.My goal is to use RS485 with auto-baudrate detection, since I have modules that operate either at 115200 baud or 500k baud.On STM32F030RCTX, I use USART1.On STM32F030CCTX, I us...
Hi,Master：MCU: stm32h743iiIDE:keilQuestion：There is a 32M external SDRAM, and the scatter file is as follows:LR_IROM1 0x08000000 0x00200000 { ; load region size_region ER_IROM1 0x08000000 0x00200000 { ; load address = execution address *.o...
Hi STM community,I’m working on a project with an STM32L031K6 paired with a Fujitsu FRAM MB85RC256V and an SHT31-D temperature/humidity sensor (on a breakout board). Both peripherals are on the I²C bus PB7 = SDA, PB6 = SCL.I’m trying to test the setu...
