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...
Hi,I'm facing some issues with some STM32G474RET6s, and want to rule out counterfeit chips, even if that seems unlikely.After googling for some solutions, I confirmed the AP IDR register and the DBGMCU_IDCODE both hold a revision ID of 3, which I exp...
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...
I cannot find any timing requirements for SWDIO or SWCLK in the datasheet, STM32L433. Where can I find this information?I don't think there is any cause for concern since I am only connecting the STLINK. However, in mass production, the wiring tends ...
Hello I have a project that uses the STM32F429 chip.Used the ltdc peripheral and spi-dma peripheral,The data of ltdc and spi both come from sdram.For ltdc peripheral,Because I want to use double buffering,I must know when the frame has completed refr...
Hello,I am experimenting on the STM32H45 Discovery Board (Dual Core) to use some GPIOs from different Core-Context.I initialized few Pins only for the CM7 and few dedicated pins only for the CM4. When I perform a debug session, all the mentioned pin...
Hello everyone, I’m currently experiencing difficulties with setting up CAN communication on my STM32F4 microcontroller. Despite having configured the CAN interface and connecting it to a CAN transceiver, I observe no activity on my designated can_tx...
Moved from this thread. HiI'm experiencing the same issue that others have reported with the STM32H755ZIT6. Despite following all the suggested solutions step by step from various forum threads, I’m still unable to debug or run code on my Nucleo boar...
