I have a custom board with an STM32U535RET6. This chip receives data from another processor using UART4 on pins PA0 and PA1. Once the data is received, it should be sent to another chip using USART3 on pins PC4 and PC5.If I transmit a fixed string di...
1. How does the STM32H562RI MCU burn firmware into the internal flash of the MCU? What Settings need to be made for hardware or software? Can it also be burned to an external flash? How is it operated?2. Can the STM32H562RI MCU be boot from an extern...
Hello everyone,I'm facing a weird issue about Flash programming on a STM32g0b1 microcontroller on IAR Workbench for ARM. ContextI'm working on a bootloader project. I am able to lock, unlock, erase and program flash at the beginning of my program. Fo...
Hello,I am working with an STM32U585I-IOT02A development board and using STM32CubeProgrammer.I changed the RDP level to DC and set a password. After that, I am unable to get back to RDP level AA.I tried entering the correct password, but the unlock o...
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...
