Hi, I'm trying to use the STLink CLI to reprogram option bytes on an STM32L4 MCU. The command is accepted, but doesn't reprogram the designed option:'C:\Program Files\STMicroelectronics\STM32Cube\STM32CubeProgrammer\bin\STM32_Programmer_CLI.exe' -c p...
Hi everyone,I'm really new to the whole concept of STM32, and I'm having trouble interfacing with my MPU-9250, which looks like: The Breakout board does not actually do much to the Invensense MPU-9250 chip, only provides some basic power regulation a...
Hello!When I connect to STM32G030 with the ST-Link programmer in the Options bytes tab, I can adjust the BOR levels (level 1-4 F and R). These levels are not described in the datasheet (DS12991 Rev 3). What are these levels and where can I find their...
Hi everyone, I am confuse about I2C pull-up resistors. I use 4 I2C sensors. I am not sure is it true that pull-up resistors count. I use every sensors for pull-up resistors. If I use just one I2C port (I mean one port for all sensors) is it enough?
Hello ST Community,I have a PCB designed according to the attached schematic.Recently, I have been struggling with the following awkward issues:1) The flashed firmware (via UART) doest not always start (2/10 attempts lead to successful code execution...
Hello!It's been a while since I'm working with STM32H7 MCUs and now, some of the products using it are returning from my customers, not working at all. Analyzing the board, I get a short circuit between 3V3 and GND and after removing the MCU, the sho...
It says we can measure power consumption of mcu by putting a ammeter at JP6 in page 23(https://www.st.com/resource/en/user_manual/um1724-stm32-nucleo64-boards-mb1136-stmicroelectronics.pdf).I write a program just detecting button, if button pressed ...
