Hi all,in my firmware I fall in a UsageFault but, since I have some tasks, I not able to understand which instruction caused the fault. Both PC and LR are pointing to the handler ..I attached the current screen.Thanks!
Hello and thank you for taking the time to read and answer my question. What I want to do:I have SYSCLK configured at a frequency of 16 MHz (using HSI), and a PLL block clock with a frequency of 18 MHz.I want to sample the PLL clock on the rising edg...
here's a link to the GitHub issue containing the build output: https://github.com/giff25/MotorTest/issuesI double checked to make sure the HAL_TIM module was enabled, and followed the chain to the .h file itself and still haven't noticed any reason w...
In my app, I need MCU to go to stop mode and then wake up by RTC timer. I follow this RTC wake up example and manage to make MCU go to stop mode for a few seconds and then wake up. Because in my app, we want MCU to wake up once in a few hours instead...
Good morning community,I am using the STM32L496QGI6 for a certain application using the uart to send and receive messages, in this case it always gives me symbols even with the baudrate correctly configured, I have checked the clock configuration and...
Can anyone give a hint on where to look for proper documentation on CAN bus development? I see some primitive examples online, though there are a lot of moments that are not explained as they shouldFor example, CAN filtering and identificator masking...
Hello ST Community,I’m currently working on a routed circuit where I’m interfacing an STM32H735IGT6 microcontroller with an external NOR flash memory (MT25QL512ABB1EW9-0SIT). While most operations seem to work as expected, I’m encountering an issue w...
Hi all, I am using STM32U575ZIT nucleo board. My goal is to write ODR register of GPIOD by using GPDMA transfer, using TIM2 to trigger the memory-to-peripheral transfer. In this "test" script, I use a 2-elements source array to force ODR all high a...
Hi,I would like to ask a question about DCMI. I am working on one task with STM32H743VIT6 MCU. My task is take an image from MT9M114 sensor using DCMI.MT9M114 is a camera sensor to capture images. Interfacing MT9M114 sensor through DCMI with STM32H74...
Hello,we use the STM32G474 with a single supply voltage of 3V3 at the VDD Pins.At the moment we investigate defective microcontrollers. The Microcontrollers are defective after several hours with the 3V3 VDD voltage supplied. The defective is an incr...
