Starting from the release in November 2025, STM32CubeIDE and STM32CubeMX will be available exclusively in their standalone versions. STM32CubeMX will no longer be integrated inside STM32CubeIDE. Instead, the two tools will be interoperable in the sam...
When configuring I2C in STM32CubeIDE, the SDA & SCL pins are automatically assigned.Can I assign pins PA10 and PA9 on STM32H743 as I2C (SDA & SCL) ?What things i should keep in mind when using pins other than the one auto assigned by STM32CubeIDE?
Hi. I have a board: SparkFun Thing Plus - STM32 - SparkFun DEV-17712Can I run the project directly via USB on this board?In stm32cubeprogrammer, I connect normally via USB, unfortunately in STM32CubeIDE, I have an error: No ST-Link Detected. I don't ...
Hey, mechatronics student here. So ive been trying to make the transition from Arduino to STM32 lately, and am a little overwhelmed by hardware-oriented programming.So I can get things like Blink running, and know my way around C good enough to have ...
A live CAN loader resides in the first 0x8000 in a STM32L431RB. I want to do a CRC check on the application that loads, following the loader, e.g. 0x08008000. The goal is for the loader to run a CRC check upon reset and jump to the app if the CRC is ...
According to datasheet, STM32H7B0VBT have 1024Kb of AXI SRAM, it is defined in STM32H7B0VBTX_FLASH.ld. But for some reason the same memory is limited to 128Kb in STM32H7B0VBTX_RAM.ld. I modify linker scripts according to my needs, but maybe I missing...
I've been fighting this really frustrating issue and have tried everything that can humanly be found on the internet (including STM32CubeIDE downgrades and upgrades on multiple machines).Simply put, whenever the program size is 64 or more sectors, fl...
HelloI am debugging my project and I found a behaviour I can't understand.I have a global struct (appModbusSlave). I can see it in "expressions". That structs has different kind of variables inside. One of them is a enumeration called "estado" (type ...
I have the FWupgrade_Standalone example loaded, looks like files marked with slash and dimmed are part of the example, so should be active files - so what does the CM7 directory icons mean?
Hi, This may be more of a general Git usage question, but I am currently learning how to use Git so I can begin to implement version control with my projects. There doesn't seem to be many examples online of embedded use, it's mostly web stuff. I use...
Hello, Two questions.First one: __attribute__((__packed__)) does not work: for a structuretypedef __attribute__((__packed__)) struct a_s { uint32_t M; uint16_t V; uint8_t Data[1]; } Type_A;sizeof(Type_A) returns 8, not 7.Second one: after S...
