I have a simple STM32H753VIT6 board with simple power circuitry and USB connection also 25Mhz xtal.I can program the board in DFU mode and verifies fine. I do not have the LSE xtal. not sure if it is needed for the USB operation. Complete circuit dia...
Dear community, I have faced with the problem in our developed boards with STM32F407 MCU. The firmware is based on FreeRTOS, vector table is located as usually in the beginning of 0x08000000 (see part of list file below). Idx Name Size VMA LMA File...
HelloI am using 2 boards with SPI communication between them: STM32F412G-DISCO as the master, NUCLEO-G071RB as the slave. The MOSI direction works well, but the MISO direction doesn't works. Monitoring the MISO line via. oscilloscope shows that there...
Has anyone successfully used STM32f407 for reading and writing SD card using SDIO? I tried creating a project with SDIO using stm32f407 with a bit of code from the sample project of FatFS_uSD using (stm32F413). And I keep getting a timeout error from...
Hi,I'm using STM32H563 and managed to set FLASH_EDATA1R_CUR as needed (EDATA1_EN="1", EDATA1_STRT="111"). Then I tried to read 64-Bit at once from Address 0x09000000. Unfortunately I get a hard fault. Is it intended to read more than 16 bit from the ...

I am currently designing a program using ST32G070 chip.As a question, I would like to create a program that will change what I was using as a PWM without using Cube Mx into a digital signal LOW or HIGH signal.I'd like to know how to change it.
Hi everyone,I'm currently working on developing a bootloader for the STM32L071 microcontroller and could use some guidance. I've outlined the basic structure of the bootloader code, but I'm looking for insights and best practices from those who have ...
Hello everyone, I have designed my own card and used F103 uC on it. I want to measure battery voltage with DMA method. I hope to drive BLDC motor with this card one day :) So i need to measure phase voltages and BUS battery voltage. Due to speed issu...
Hi, We are using STM32L010C6 Microcontroller, we need to recive the a fixed size of strings (10 charecters ) using interrupted method. But we are not able to receive the charecters completely and its get stuck on the cpltcallback function also. What ...
