I am working on a prototype board using the STM32H725VGT, based on an existing custom board where LWIP/RTOS Ethernet is already working. Since I have a preference to keep the same MCU for the next design, I am evaluating its ability to support an 8-...
Im building some phase shifting control sensing for a Dual Active Bridge.Im using TIMA and TIMD (shown in pictures) in retrigerable single mode, both signals are triggered by sepparate CR from the master timer. https://community.st.com/t5/stm32-mcus-...
Hi,I am encountering a hard fault on my STM32F407ZG when using snprintf(). We are using FreeRTOS for the development.The system resets due to a precise data access violation (PRECISERR).Below is the fault status: HFSR: 0x40000000 BFAR: 0x38383600...
Greetings!I have a board with STM32H747XI and SN65DSI84-Q1 as a converter from DSI to LVDS.The issue is that I can not get video output from MCU to 2ch LVDS panel 1920x720 with any configuration I'm trying. The main issue is that I'm getting HAL_DSI_...
Posted on March 11, 2018 at 23:41Hi !I'm excited to join the ST community! I hope someone can solve my problem.I am experiencing timing issues when converting an ADC.Here is the configuration of my project:- The timer 3 is configured in center align...
When using DMA to do a SPI transmit, I found a strange behavior. The problem is, that the communication to the DAC works for a few seconds, depending on the used frequency. After the few seconds only 1 byte instead of 3 bytes are sent and the NSS Pin...

I noticed that for STM32L010F4 in stop mode (“HAL_PWR_EnterSTOPMode(PWR_LOWPOWERREGULATOR_ON, PWR_STOPENTRY_WFI);”) the power consumption is around 330µA when the STLINK is connected to the MCU. When I disconnected the STLINK debugger wires, the powe...
Given an MCU (say an STM32H755ZIT) and a function (say SPI2_MOSI), how can you find which pins may be configured as SPI2_MOSI, short of clicking on every pin in the Pinout View of the MX Device Configuration Tools?
I'm using the STM32H753ZIT6 NUCLEO Board. For some reason the User LED's are on by default even without any code on it. I tried to press the reset button but it would just blink the led's. I read on another forum to short the BOOT0 and Vdd pins but w...
