Also, I heard "Pull-up resistors are not require because STM32F already have one." is that true? Please help me about it. I will be really appriciated.
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?
STM32L073RZT6 hardly booting the firmware
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...
Short circuit on STM32H750
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...
How to measure power consumption of Nucleo-L010RB?
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 ...
I have multiple ST-link's but no option to select the ST-link in STMStudio.
I have multiple ST-link's but no option to select the ST-link in STMStudio. Could you help me find it. Or is there any standalone debugger for STM? I really don't link ozone. Because it is consuming too much memory.
dual boot for stm32l151re not working
i am not able to run any code on bank2 with STM32L151RE with 512kB FLASH.program was loaded on both regions 0x0800 0000 and 0x8004 0000if nBFB2 is checked the code runs ok, if i just unched the code does not run....what am i doing wrong?
MB1440 circuit diagram
Hi All,Does anyone have the circuit diagram (schematic) for this board?Basically (and I have posted about this before, without any conclusion) I have several boards which work perfectly (sw download and SWD debug) via the big 20-way CN2, but are unre...
Resolved! What is the temperature range of the nucleo-u575zi-q evaluation board ?
my goal is to use this board in [-40°C +85°C] climatic chamber.Regards:)Oliver
