Hi everyone,I’m currently working with the STM32H533RET6 and I’m wondering whether an external crystal oscillator is required (or at least recommended) for reliable communication over RS485 and CAN.From my understanding, even at the highest baud rate...
Hello,Just before I tried to debug STM32L052 via ST-Link but following error occurred.The error message is as following.It's strange that I could debug and run with same project yesterday and nothing is changed as for project.What is the problem and ...
I am new to the STM32N6 and wanted to to knwo where could I get the documentation that explains the APIs of every peripheral in the STM32N6 MCU.
Hi, Is there a LL Library project example or at least a code snippet of how to transmit uart data using the GPDMA?
Documentation: RM0390Revision: Rev 7, June 2025Section 26.3.2 Page number 830:Under Simplex communications, it says the RXONLY bit is in the SPI_CR2 register but the register map confirms RXONLY bit is in the SPI_CR1 register.
Hi everyone,I'm currently working on project witch use SPi with DMA and S2LP ModuleI have a function that initializes the DMA portion :In my code I try to read information in DMA through the SpiritDeviceVersion and SpiritReadnbinfifo functions: Howe...
-->According to the datasheet and reference manual, I learned that the microcontroller has 64KB of memory, and I tested it and was able to read/write on pages 29, 30, 31. But why does the website say it has 32KB? #define FLASH_SAYFA_SAYISI 3 //#defi...
Hi,I’ve been struggling to get an image from an image sensor using DCMI via GPDMA on an STM32U595.The sensor outputs a 1280x800 image in 12-bit RGGB Bayer format, which I’ve configured correctly. That gives 12 bits per pixel, and I want to capture th...
Hi,In STM32H56xx, if both EDATA1_EN and EDATA2_EN are set to 0, can I place application code in the high-cycle data flash memory?I am confused by these two descriptions in the reference manual:“A threshold per bank (EDATA(1/2)_STRT) is programmable i...
Hi everyone,I’m facing an issue with power consumption in STOP2 mode on my custom board.The board includes only the STM32U595 MCU, bypass and decoupling capacitors, and the inductor for the SMPS — nothing else is connected.According to the datasheet,...
