Hi,I have a custom developed stm32 project with stm32f411ret6 mcu, i have done my full board and got the pcb printed. I have a 4 pin header on my pcb with vcc,gnd, swdio, swclk for uploading the bootloader for the first time. I have done this several...
Hi all, I'm using Nucleo H755 I have configured UART with 115200 baud rate and the Rx in Interrupt mode issue: While the STM is configured with 115200 baud rates, when I transmit some data with the same baud rate either the data is corrupted or data ...
Dear ST community member,I am new to ST platform.I am using STM32G030C8T6 Development board from 7 Semi and ST Link V2.Dev board link: https://evelta.com/7semi-stm32g030c8t6-arm-stm32-mini-development-board/?srsltid=AfmBOorI6XBlJ_AMXNVV184OhO-lB02AFO...
Goodmorning,I am using STM32L552RCT6 in my design that I intend to use through a USB interface.I'm trying to implement the VBUS sense (compulsory since my device will be self-powered). I have read AN4879, and it's clear to me that I have to add a vol...
Dear ST Forum members,I am developing the Prototype with STM32WL microcontroller to which I provide a schematic snippet below:+ SWD 1x5 goldpin connector:If the image quality doesn't let you inspect the nets, I will provide a better image later.The 3...
I was reviewing the schematic for the STM32H7x3I-EVAL board and noticed that the ETH_nINT pin from the Ethernet PHY is connected to pin PG7 of the microcontroller.I'm having trouble finding clear documentation on how this pin functions. Could someone...
I’m designing a minimal breakout board for the STM32H757IIT6 to power it up and access a few GPIOs. The purpose is purely learning both about the STM32 dual-core system and PCB design. Since I’m a beginner, I’d like suggestions on anything essential ...
Hi,I am designing a custom board based on the STM32H753, and as part of the design process I am reviewing the MB1246 and MB1331 evaluation board schematics for reference.While studying the display interface, I noticed the following discrepancy:On the...
I am currently designing a custom board based on the STM32H753 microcontroller, and I am studying ST’s evaluation boards as reference designs for the external SDRAM interface. While comparing the schematics of MB1246 and MB1331, I noticed a discrepan...
I’m using an STM32 board to drive an SSD1322 128×64 OLED display with my own driver library. It used to work fine without issues. Without changing the code, the display suddenly became completely unresponsive. - Power supply shows 0A current draw (no...
