Hi everyone,I'm experiencing an issue uploading a simple onboard LED blinking program to my STM32H755ZIQ board. Every time I try to start a debug session, I get the following error:STMicroelectronics ST-LINK GDB server. Version 7.9.0Copyright (c) 202...
Hi, guys, I've bought STM32H745I-DISCO board to make an EtherCAT master, so I successfully employ EtherNet controller, USART3 for debugging but SPI2 has a problem. (I'm mostly novice fir H745) I decided to use SPI2 for communication with exte...
Hello, I have seen in the post That many users had a problem with the LDO power supply for STM32H757ZII wanted to ask, can you confirm that I have a correct implementation of the power supply for LDO?
hi im using stm32g474vet6 mcu , im using spi in dma mode of both tx and rx and made dma in circular mode.what happens means when i start a first tx or rx itself spi clk is coming continuously. what to do , it is due to circular mode.if (send_spi_cmd ...
I m trying to communicate through USART with my NUCLEO-L476RG but the STM console is displaying nothing. I have created a simple project:I m overriding the __io_putchar function:int __io_putchar(int ch) { if (ch == '\n') { uint8_t ch2 = '...
I am making a stm32f411ce board and I want make sure everything works because it's very expensive to order a pcb in my country. I want to use components like Hc-49 8mhz crystal(and dt-38 32.768khz) oscillators with ceramic PTH capacitors, the only sm...
HI there, I own a couple of STM32H747-DISC0 boards for a year. I been using them without issues debugging but when started a new project, I do not know what went wrong that cannot access to any core from any ST tool (CubeIDE or CubeProgrammer).No mat...
I bought a 1Set STM32F407VET6 Industrial Control Board from AliExpress to evaluate the STM32 MCU family but I can't find any information about it. 1Set STM32F407VET6 Industrial Control Board I've used many different Arduino, Teensy, ESP32 and other s...
Hi there!Im new with ST MCUs and im using a Nucleo F429ZI, i have some documents and one of them is the 'nucleo-f429zi.pdf' but is too short and doesnt have too much informationIm working with user push button connected to PC13 but i want to know if ...
