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...
Hi,I have a ethernet project running on a H743 and H753. The H743 is working fine. The H753 is not working.If the ETH_MAC clock is enabled I can see that the SWR bit in the DMAMR is set (software reset) and as soon as the RMII is selected as interfac...
Hello everyone. Does have anyone a sample project about how to run Ethernet on stm32f429 discovery board with DP83848 as PHY without FreeRTOS? Including CubeMX project and IAR, KEIL, or CubeIDE as toolchain.Thanks in advance.
Hi,I am trying to transmit the data(USB CDC) over PC but I didn't see any message printing on Serial Putty Console. Do I need to change any configuration settings. May I know , why transmission was not happening.. I am trying to dig into deep. so cou...
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...
