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...
