I am developing in C++ on a STM32U5, with HAL and was trying to figure how to embed interrupt handling in a class.So I've questioned ChatGPT and DeepSeek for a solution and both gave an answer using pUserData field for storing object reference.pUserD...
Hi, I am trying to make the MCU the host where a USB can be connected, and the MCU can read/write to the USB. I configured my IOC /CubeMX to use the USB with FATFS. The USB USE OS (RTOS) is automatically enabled.However, the issue is that once the US...
Hello,I have been facing this issue of "No source available for "<signal handler called>() at 0xfffffffe"" on a nucleo-h753zi board. Following are few logs obtained from STMCube Programmer.1. Fault that is eesca;ated to a hard fault (forced)2. Faulty...
Hi Experts,We are building a battery based product based STM32G030F6 MCU. We are using Arduino environment as we need multiple Arduino libraries for the project.Well our software is working fine, however we are facing issue with the current consumpti...
Hello ST Community, I am currently working on a project using the STM32U5G9ZJT6Q MCU. My application involves sending data over USB using CDC-ACM mode. While the code appears to be working correctly, I am encountering an issue where the execution get...
I am developing a project with STM32 using the STM32G473CET6 chip and working on a CAN bus system. In this project, the STM32 sends messages to the bus, processes the received messages, and responds accordingly. For example, the message 10170001 quer...
