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 everyone,I want to use CAN with my STM32F103CB and STM32F429ZIT, but the CAN TX and RX Pins do not do anything on both boards. I am using CubeMX 5.3 and F1 Lib 1.8.0 / F4 Lib 1.24.1From the CubeMX CAN example project for the STM32446E_Eval board I...
I am designing an application with a control loop of 1 ms, and I would like to use HAL_GetTick() as the way of clocking this loop. This is a safety critical system, and I would like to know if one will run into a race condition by calling this functi...
Hello, I'm doing a project where two microcontrollers (maybe one STM32H7 and STM32F7) must be connected between them. These two microcontrollers should be connected to an external Ethernet port. Is there some type of hub or multiplexer that allows t...
Using FreeRTOS on a STM32L476RG we get unreliable boot behaviour because CubeMX generates:... /* Initialize interrupts */ MX_NVIC_Init(); /* USER CODE BEGIN 2 */ /* USER CODE END 2 */ /* Call init function for freertos objects (in freertos.c) */ MX_F...
I'm wondering how things work *without* VBUS sensing on, in particular, the STM32F401. From the documentation, I understand that:VBUS sensing can be disabled for bus-powered devices, since these are only powered up when VBUS is present, so VBUS can b...
Hi, I have an application; where I need to keep on running a hardware timer with microseconds resolution. I will note the time when some external interrupt is triggered. Basically purpose is to note the time difference between external inputs/trigger...
Hello, ST expertsSTM32F415 runs at 168MHz speed on custom board. And UART1 is used between MCU and a peripheral. The UART baudrate is 460800bps. And UART1 global interrupt is the highest priority interrupt except Non maskable interrupt and Hard Fau...
I am developing code on my PC that uses Serial Comms to interface to my STM32H7xx and STM32F7xx processors using the system bootloader on USART1.I have successfully loaded code on both processors into both bank 1 and bank 2 and can jump to and run th...
Hello,I am trying to connect RaspberryPi (master) with STM32 (slave) via I2C. STM has to "simulate" several devices (exactly 10) on the I2C bus. The problem is that I can set max 2 addresses (at least in Cube - HAL libraries). Ideally it would be lik...
