Initially, I ran a program from Simulink onto my STM32H755ZI, but I encountered an issue where only one core was functional, even though the STM32H755ZI has two cores. This led to the error "No device found on target."As I continued troubleshooting a...
Hi,I am experiencing an issue with my ST-Link V2 debugger. When I connect it to my PC, I often receive the error: "USB device not recognized: Unknown USB device (Device Descriptor Request Failed)" and ST-LINK orange LED turns on. However, after sever...
Hello everyone,During some test I try to change the type of the StLink-V3 of the NUCLEO-H7A3ZI board to "STM32 Debug + VCP"After this I can't flash or connect to the board even if I update back to "STM32 Debug + MAss storage + VCP".I try to erease th...
I have the below code, which is supposed to update DAC with sinewave via SPI3 bus. It was configured and working fine via discrete command, but when I used timer7 to generate an event and update DAC16 via SPI3 via the HAL library, it went to hard fau...
Hello,I'm new to embedded programming, and I'm currently working on establishing a basic SPI connection between an STM32 microcontroller and the BMI270 IMU sensor by Mikroe. My goal is to read the Chip ID (CHIP_ID register at 0x00) and get a response...
Hello,I am a PowerTrain Electronics Hardware Architect by profession.For one of my new hobby electronics developement I decided to use STM32 micro controller.To start with I bought NUCLEO_F030R8 and able to blink on board LED as I program. Then I tri...
so i was following an online tutorial (from digikey, where they teach how to use dma) and in it the values from ADC is transmitted through DMA to a buffer of decent size (4096byte). But it seems they always use the hal delay function after using uart...
I am experiencing a bug in the ST-Link FW V2.J37.M26setupNucleo-F446RE power from E5Vit takes a long time to "boot" or start to execute code. some code will never start running. the problem goes away if the ST-Link is power from USB before E5V is tur...
Hi ,I Cant load the code or debug it in the dev board using my IAR workbench .it looks like some error with the flash loader.Sat Feb 15, 2025 09:08:58: IAR Embedded Workbench 8.50.1 (C:\Program Files (x86)\IAR Systems\Embedded Workbench 8.4\arm\bin\a...
I am traying to meassure a clcok frequency using STM32F103C8T6 board i am unable to capture. Please anyone solve my problem. This is the code i am using. #include "main.h" #include <stdio.h> #include <string.h> #define IDLE 0 #define DONE 1 #def...
