Ask questions and find answers on STM32Cube packages, including HAL, LL and middleware, and expansion software.
Get early access to the next-generation STM32Cube HAL drivers for STM32U5A major update to STM32Cube HAL drivers, called HAL2, is now available for preview on GitHub. It supports the STM32U5 series. Building on over 10 years of experience, HAL2 deliv...
hi, This is question regarding UART reception.UART configured with 115200 8 N1 I have a project where i need to receive a multibyte packet on UART and the length is not fixed.My Queries 1> Which approach should I take to receive a multibyte packet.2>...
I'm using HAL SPI drivers to read some MCP23S17 expander chips. I am sending a 2 byte command and receiving a 6 byte response. The trouble is there is 6 mS of delay between the write and read. Code: // read encoder expander chips for encoder button ...
Posted on November 17, 2017 at 20:27I have already read several posts about the subject. including 'DFU: LEAVE does not jump to application'.and 'Reset after firmware upgrade'Context : STM32F072RBusing either DfuSeCommand.exe or DfuSeDemoUsing the D...
Hello, I am doing a project wich takes audio from an ESP32 via I2S, process it and then send bia i2S to an amplifier wich manage I2S signals as input.HARD:ESP32 (source of audio)ST nucleo F401Re (processing unit)Amp: MAX98357A.I manage to make work p...
I have callback ISR code (from UART) where I put in Semaphore put and other code with Threadx static implementation with stack (SRAM2), Semaphore get, etc. I placed two GPIO signals to measure the timing between put and get. I set the compiler to opt...
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...
