I am working with an STM32C092CCT6 (STM32C0 series) and I need help with reading and writing variables into Flash memory.I want to store a few configuration values (like integers or structures) that should persist after reset or power cycle.From what...
I'm using the STM32F103C8T6, and trying to blink my LED via the interrupt handler of a DMA with this code#include <stdint.h> // STM32F103C8 is a medium density device, hence we use the xB header #include <stm32f103xb.h> #if !defined(__SOFT_FP__) && ...
Some of the STM32 CPUs have a USART with a Timeout timer which is good for modbus applications.Is there any overview available which CPU devices have this specific periperal implemented?In the Datasheet this function is called RTOIE, or RTOR.
Hello everyone,Hope you are all doing well. I am currently working on a BMS that includes an STM32L562VET6Q MCU and other peripherals.ARINC429 is completely new to me. This week, I have been reading the ARINC 429 (HI-35850) datasheet and trying to co...
Hello... I'm learning to use an external ST-Link to debug the F446ZE Nucleo using SDW. Can anyone advise on how to connect the SDIO, SDW pin on the Nucleo board to the external ST-Link v2? Additionally, what settings should I configure in CubeIDE to ...

Hello everyone, I'm using the USART 1 of the STM32U375-KG. Regarding this I have two questiones:1.) Can I use UART CTS (clear to send) and DE (driver enable) at the same time? In the device configuration tool I can only select "CTS only" or "Hardwar...
Hello ST Community,I’m looking to upgrade the MCU on an existing board originally designed around the STM32F769 (LQFP176 variant). I’d like to know:1. Is the STM32H743 or H753 (LQFP176 package) **pin-to-pin compatible** with the STM32F769 such that i...
Hello,I am currently learning low level embedded programming, which lead me to try to extract the data used to generate the table 51 of the document RM0394 Rev 5. I would use this data to generate C++ code. Is the raw data of this table is publicly a...
I write six 32-bit floats to RAM every 10 µs (100 kHz) via DMA. I batch and flush every 10 ms → 1000 samples × 24 B = 24 kB per block → 2.4 MB/s average.RAM buffers: planning double/triple buffering (48–72 kB) in SRAM1/2 (CCM isn’t DMA-accessible).SP...
