Resolved! I²C Bus Stuck Issue – STM32G0 Slave Holding SCL Low During Hot-Swapping
Hello ST Experts,We are implementing a hot-swappable (plug-and-play) I²C system with STM32G0 slaves, but we are facing an issue where the I²C bus gets stuck due to SCL being held LOW. We need guidance on how to resolve this.System Overview:Master: ES...
Change Period/Pulse of HRTIM based SimplePWM
Custom board, STM32H747 device, Simple PWM Using the code generated by MX, and adding a call to HAL_HRTIM_SimplePWMStart, I can generate a nice simple PWM output signal. If I change the initial values for period/pulse, rebuild, and program to the dev...
Encoder mode
Hello everyone, I am currently working on encoder mode with an STM32C031. I am using a DC motor with an incremental encoder and a gear reducer. My goal is to measure both the velocity and position of the motor. I have configured Timer1 with a frequen...
Resolved! PWM Duty cycle control with __HAL_TIM_SET_COMPARE
I am working on a project that I aim to control a boost converter using a stm32 f407 disc kit. I want to control pwm duty cycle with two different integers which are x and y. I want my duty cycle equal to (1-(x/y)) how can I do it

STM32H7 DMA stops after first transfer
I tested this example from the STM32CubeH7 repository and it works fine.When I try the DMA1 instead of the BDMA, the DMA stops after the first transfer.I made only the following changes to use the DMA1 __HAL_RCC_DMA1_CLK_ENABLE(); // Enable the cloc...
Resolved! Problem with connecting STM32H755ZI-Q
I am new to using stm32 MCUs and I was following a youtube tutorial on how to set up a debugger for dual core MCUs. Before changing some settings I was able to start the debugger without any errors. Now when I try to run the debugger I get this error...
Resolved! Clarification on Debug Register Configuration in STM32H755
Hi,I'm working with the NUCLEO-H755ZI-Q, which features dual cores (Cortex-M4 & Cortex-M7). I’m trying to understand whether these two cores have separate debug registers, such as DHCSR (Debug Halting Control and Status Register).I have reviewed RM03...
STM32L432 dynamic VDD voltage change
I'm developing a very power-saving product. The STM32L4 is a really great product for our application ! Usually I run the STM32L4 VDD at 1.8V. Operate at 3.3V only when end user configures it via USB. The problem is that I want to switch the VDD volt...
