Hi all, I'm planning to use USB (DFU mode) for production programming of the STM32C071K8U6 — including the very first firmware upload. The board has no external crystal; I intend to rely solely on the internal RC oscillator. A few questions: 1) Is ...
Hello,I am designing a high-speed data logging architecture using STM32H743VIHx. I would like the community to validate my DMA architecture and answer specific questions about eMMC access. I did not find answers in the forum and I am also not an expe...
Hello, ST expert For GPIO structure, what are the differences between FT and TT mode? Are there any differences for the ESD diode and the other diode in these two modes? BR Yang
Hi All,I've just been watching an ST tutorial video on how to implement bare-metal Device CDC USB on an STM32U3.During the video, the lecturer says that the code is available within the workshop download. No link is provided to the workshop code......
Hi All, I want to do something very basic, but somehow cannot manage to do it. What happens if you have a PWM signal on an IO Pin, generated by a timer, and you disable the timer? What happens to the physical IO Pin ? Is it stuck at the state whe...

Hello ST Community team,I would like to report a possible inconsistency in the STM32 MCU Portfolio Selector regarding Ethernet filtering for the STM32C5 series.While selecting MCUs using the Portfolio Selector, I filtered devices through:- EthernetTh...
Hi, we have purchased stm32h750vbt6 microcontroller for analog signal validation with 10k potentiometers to integrate with game controller joystick especially joy.cpl using windows 10 OS. We have dealt with DMA Circular mode configuration pointing ...
Hello everyone,I have encountered a strange issue with my UART transmission function on an STM32 microcontroller operating in Half-Duplex Open-Drain mode.Currently, the function works perfectly fine without checking the TC flag. However, when I add a...
Hi,I am using the STM32F407VET6 chip to simulate the SENT protocol. I have encountered some issues and would appreciate it if professionals in the forum could provide some answers.1.Since the SENT protocol signal needs to change the output waveform b...
