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...
I'm using a STM32F070RB nucleo board with STM32CubeMX to implement a USB CDC device. After generating my project (and increasing the stack size minimum), I'm able to transmit data from the Windows 10 host to the CDC device by editing the CDC_Recive_F...
I'm testing an UDP client/server using a NUCLEO-F429ZI (Ethernet).Code is generated thanks to STM32CubeMx.I'm using FreeRTOS and LWIP.DHCP, ICMP and UDP are enabled. TCP is disabled.IP stuff is done using socket API, one thread for receiving, one thr...
Datasheet DS12536 Rev 1, page 45 says:-----------------------------------------------------------------The STM32F730x8 devices feature a UTMI low-pin interface (ULPI) for high-speed operation (480 Mbit/s). When using the USB OTG HS in HS mode, an ext...
