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...
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...
Hopefully i chose the right thread, right so i have sn stm32h523 chip running a PCISPH fluid simulation, but its incredibly slow, that was expected, which is why i optimised the algorithm to include spatial hashing to reduce particle-particle computa...
There's a serious bug in G4's hal(version 2.0.0) library in spi dma function.The problem is:1, user calls HAL_SPI_TransmitReceive_DMA2, after spi transmission finished, HAL will call HAL_SPI_TxRxCpltCallback3, user calls HAL_SPI_Receive_DMA inside HA...
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, ...
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...
I'm developing a project using an STM32 Nucleo board. At the core of this project is a UART-based communication protocol running in interrupt (IT) mode — not polling or DMA. This protocol is responsible for controlling multiple subsystems such as a r...
The Cube-AZRTOS bundles cmsis_os2.c implementation has potential NULL pointer dereferences. There are many lines of the form:if (( attr->cm_mem == NULL) || (attr == NULL))in code that attempts to recover and de-allocate memory from a "create" call t...
