On the STM32F303K8, is it possible to configure e.g. PA8 to both receive an EXTI interrupt on falling edge and act as the TIM1CH1 input to trigger source TI1FP1, in turn serving as a timer gate for gated mode? I cannot find a way to express this thro...
Hi i am working on a project with STM32H7A3VGT6 chipset which has LTDC controller. my goal is to make a LVGL based UI with SquareLine Studio and interface a 24 bit parallel RGB display with it . so i have made a UI using SquareLine Studio and importe...

Hello all,I’m hitting a USB edge case on an STM32H573 in the 68-pin package (no VBUS sense pin, no VDDUSB domain).My setup (works fine in application):The product is self-powered (3V3 is always on). Because the package has no VBUS_SNS, I detect bus p...
Hi,I want to use LPTIMx to output a PWM signal that changes duty cycle on each period with DMA. The HAL driver implementation for LPTIM PWM is completely wrong, so I tried to find out how to do this from TRM etc.LPTIMx has 3 DMA request events:2xCCRx...
Hi, For a reason that I cannot explain, the STM32U575ZI (on the nucleo board) is sending a CAN bus message with infinite repeats and 100% bus utilisation, but I have repeated transmission turned off (DAR bit set to 1) and I have confirmed this using ...
Hi I'm playing around with the RTC & tamper peripherals of the NUCLEO-H7S3L8. I'm wondering if the TSOVF can be set when multiple tampering are detected in VBat mode ? If I'm not mistaken, the RM doesn't say anything against it. However, using the RT...
Hi everyone,I’m trying to generate a square wave using TIM5 Output Compare (OC) on an STM32H7 board. I configured TIM5_CH1 to output on PA0, both in CubeMX and manually in HAL_TIM_MspPostInit(). Here is a snippet of my GPIO init: GPIO_InitStruct.Pin ...
Hello,I am working with STM32H743, using ADC1 and 2 in dual simultanious mode, using DMA to store data from ADC_CDR (2 16 bit values) to memory, some hundred values in a stream in continuous mode. This works fine in general but I frequently see a mi...
Hello Community, We are using an STM32U595ZJT6Q microcontroller and have connected an MB85R4M2TFN-G-JAE2 FRAM via a parallel interface. The setup works well under normal operation and even after a power cycle — all data is retained and verified corre...
