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...
STM32 HAL driver library is full of flawed and sub-optimal constructs. The most common one, which impacts almost all drivers, is the lock mechanism. It's a bad and limiting design and getting rid of it requires a major rewrite, but the worst fact is ...
Hello,I'm using STM32G0B1-Nucleo (with no USB user connector), and I am trying to program USB device (I tried virtual COM, HID and MSC separately).I'm using the STM32CubeMx with STM32CubeG0 FW V1.5.1 to generate the configuration with PA12 and PA11 f...
I need to run SysTick every microseconds instead of every millisecond. So I called: SysTick_Config(SystemCoreClock / 1000000);except that delay never ended, because the interrupt was low priority so: HAL_InitTick(TICK_INT_PRIORITY);Except this s...
Hello,I'm working with a STM32F767, on a custom pcb and a Nucleo-144, same behavior, so it's probably not hardware / board related.Source code:Bare metal, no OSSAI to ETH, via DMAETH: zero copy Tx & Rxhttp server (TCP) works perfectPTP via UDP works ...
Hi,I have a general question regarding the problem I am facing.Currently, the pSpeed Value is very small (for example 3.4E-7) and when I perform a square for such values it becomes smaller. When I pass the Square data value to the arm_sqrt_f32() func...
Hello, I've asked Truphone and they activated the eSIM for me, but the B-L462E-CELL1 still can’t connect to the internet. I've dragged and dropped the X-CUBE-CELLULAR-7.1.0 binary file onto my device using ST LINK, please help to check. You can ref...
HiI have working TraceX on Nucleo STM32U5A5 (as per MOOC TraceX section) as long the TrackX buffer (64K) does not get full. In event it get full, it leads to this error: "Unable to Read Event - Possible Trace File Truncation". I even put notify whe...
Hi,I am building some FREERTOS appplication with ARM cortex M4 micro controller based on STM32F4 discovery board.The program compiled successfully with 0 errors and warnings with eclipse IDE. I am using STM32Cube IDE.But, when I tried to load the pro...
Hi All,I am working on the STM32U575 for host mass storage class.I am not using stm32 middle ware for this due to some reasons.I am using TinyUSB open-source stack to implement the Host mass storage class.with my current implementation I am able to u...
Hello, I am using a STM32G473RC microcontroller and want to use usart3 to update the firmware.I also use the CAN-BUS on pin PA11 and PA12. These pins (PA11, PA12) are also USB pins (DP and DM).When I start the bootloader (BOOT = 1 + RESET), the "USB ...
