Hello I'm migrating my STM32F072 project to the STM32L072.In my original project (F072) I can jump to the DFU bootloader by software via a function located before SystemInit.I tried to convert this to be used by L072 by changing the address of bootlo...
Hello, I'm using a STM32U5GJ-DK1 with the same SPI setup, I can measure the SCK output on SPI2, but I can't do it on SPI3. *This post has been translated from Chinese to comply with the ST Community guidelines.
Dear ST Community I recently purchased two sets of Nucleo-DRP1M1+NucleoG474, and now I want to implement FRS functionality on these two boards. Currently, I have set one of the default power roles to Source, enabled FRS_TX, and the other to Si...

Hi there, follow the attached picture, an easy question for you, for me an effort. left side:Compiling procedure for a simple 32-bit binary file, ARMright side:program code - board LED should turn onresult:turn on LED - failed Questions:AIn my opini...
First of all I am not sure if this is the right location. It wasn't: you posted under MPUs; moved to MCUs.I have a custom PCB with an STM32H5 chip embedded.This PCB needs to be a USB Host for a sensor that uses USB. If I connect the sensor to my lapt...
I'm trying to trigger ADC using an high resolution timer with period 500 KHz. The board is STM32F344. ADC is using DMA. I'm using FreeRTOS CMSIS V2. System clock 64MHz. So, two issues immediately came up: 1) After launching the timer using HAL_HRTIM_...
HelloI have a custom board with a STM32H730 and SD Card connected to the SDMMC peripheral, quad lines. I'm using the FatFs file system as added in CubeMX.My question is why does the file write rate drop after the first file (open/write/close) unless ...
Hi, I see these functions have essentially the same functionality, is there any recommendation on which to use? I understand snprintf has the advantage of formatting other data types into the string, but for simple string = string functionality, doe...
