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...
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...
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...
Hi Team, We are using the STM32H753VIH6 in our design. We are connecting the Realtek RTL8364 through RMII interface.Connections are in the attachment and we have validated link between the two.I have captured the waveforms , but the voltage span look...
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
Hello everyone,I am currently working on an STM32H745ZI-Q dual-core project and want to generate the code using CubeMX, compile and flash it with PlatformIO, and use CLion as my development environment.My primary goal is to understand the best appro...
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...
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...
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...
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...
