Hello everyone,I was reviewing the AN4899 Application Note and noticed a potential logic inconsistency that might lead to misunderstanding the GPIO output stage. I have prepared a short analysis and a proposed correction below. I would appreciate it ...
Hi, What is the official moisture sensitivity level (MSL) for STM32F072CBT6TR? I found conflicting information showing both MSL 2 and MSL 3.
Hello ST Community,I’m currently trying to select the right MCU/board from the STM32H7 series, but I’m a bit confused between the following options:STM32H723STM32H725STM32H735STM32H7A3VGT6My requirements:Need CORDIC support for fast math operationsR...
Hoping someone can assist.I have a 2 x 8 segment numerical glass LCD that I want to drive from the MCU.See two images below & uploaded files with this request.snippet from LCD data sheet.snippet from CubeMX pin out view.This display is Static with to...
Post edited by ST moderator: title and post edited to translate the content. 我在stm32F412RGT6的数据手册的6.1.6部分看到关于滤波电容的描述，2. The 4.7 µF ceramic capacitor must be connected to one of the VDD pin.从图中来看是以144PIN的芯片为例，但我使用的是64PIN的封装，是否也需要在其中一个VDD引脚放置4.7uf的电容，如...
Both 'U5 ADCs contain the LFTRIG bit; however, I could not find in either 'U5 datasheet the Tidle value above which this bit has to be switched on.JW
I'm using the STM32G474 at 170MHz. Is it possible to simulate hadc1.Init.ClockPrescaler = ADC_CLOCK_ASYNC_DIV512; since the G474 only recognizes up to ADC_CLOCK_ASYNC_DIV256; I need very slow readings from the ADC. Thank you Valter
Dear Community, I am researching how to use a 50Mpx MIPI CSI-2 2 LANE RAW 10 sensor with stm32N647.The idea is not to use the full sensor, instead using analogue/digital crop and windowing on the sensor to capture a specific part of the image and dow...
Hi all, I have reached the point of desperation, and I am all out of ideas how to get my STM32U031 project working.I designed a very simple PCB which has only a few components. I have attached the KiCad files in case it is helpful. I followed guideli...
Hi,I have made up six boards and three of them had an unusually high standby current (35mA instead of 1mA).Eventually, when the IC was removed, we found Pins 5 & 6 of the removed IC were shorted internally (0.3R)They were also shorted to pin 45 with ...
