Hi all, apologies if I am missing where this has been explained. It seems a relatively common question, but I have not found a definitive answer.A legalistic reading of the datasheet says that there is no difference whether the pin is configured as ...
Hi all,I'm using an STM32U5G7VJT6Q on a custom design PCB. From the application, I jump to the USART (UART1) system bootloader. I then try to connect to the bootloader via STM32CubeProgrammerCLI. The jump to the bootloader appears to be correct and t...
Hi guys, im making system wchis is sampling data from 2 microphone channels.I need to make it pass at least 8 kHz/8 bit/2ch data which i already did. The problem is that i'd like to increase the audio quality of transmitted data, and it's easy on the...
Hello, I'm trying to transfer a 4000 uint16_t buffer from SRAM4 to DTCM. This is working with a basic configuration of the MDMA module : - Buf size = 32 - Block len = 4000 - No burst mode - in/out size = half word. The MDMA needs 135µs to transfer t...
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...
i use STM32N6570-DK to do a simple project but i cannot get any useful info via printf() on SWVITM data console. (1) I add some code in systemcall.c for printf() on SWVITM data console or UART1 via a "define" in my main.c. (AS many professionals sugg...
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...
