nucleo-c092rc CANFD 8Mbits not working
Hi, We are busy making a setup with 2 nucleo-c092rc boards. Our first test was to send from board 1 to board 2 by the integrated CAN interface on these boards. We started at 1Mbits and this worked great. Also on 4Mbits the setup worked great. But we ...
Resolved! What is the differences between TT and FT mode for usb pins PA12&PA11 in STM32U595?
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
Resolved! MOOC-STM32U3 Hands-on - 04 USB Device CDC bare-metal - Workshop code
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......
Resolved! Stopping a Buzzer driven by Timer 16, STM32G071
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...
Resolved! Issues on the STM32 Portfolio selector - Ethernet on STM32C5 series.
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...
Resolved! USART Half-Duplex Open-Drain: Waiting for TC flag causes garbled data
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...
Some issues regarding STM32 simulation of SENT protocol
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...

Resolved! How to do ESD protection to USB_D+ and USB_D- when USBPHY is not powered for STM32U595VJT6
Hello, ST experts It is found that USB_D+&USB_D- pins(PA12&PA11) of STM32U595 in our own design are very sensitive to ESD strike. When USBPHY power is not on as reference manual said, I think it is only 3.3V tolerant in this case, but not 5V tolerant...
