Ask questions and find answers on STM32Cube packages, including HAL, LL and middleware, and expansion software.
I am using a custom board which includes a uSD that is interfaced to a STM32F765 through the SDMMC1 pins. The clock rate is set to 48 MHz. I am using the stm32f7xx_hal_sd driver to read and write to an uSD card. I initialize the driver with a call t...
Hi,In a matter of days, I'll have to port a user bootloader from STM32F303 to a STM32G473 mcu.The question is about the Dual Bank feature of G473: since Dual Bank is active by default (DBANK=1), I'd prefer to NOT switch to Single Bank (as it is neces...
I want to use hardware I2C (which is only available on pins PA9, PA10 on the STM32F030F4P6 in TSSOP20 case). That overlaps with the standard pins used in the bootloader code for USART1_TX and USART1_RX (AN2606 Rev 55, page 50). The alternative pins u...
Greetings to the ST community,I was using the example project provided by ST in "STM32F769I-Discovery\Applications\Audio\Audio_playback_and_record\EWARM" and found out that voice was being output through the headphones. However I connected speakers t...
I'm trying to use fileX for format a card with filex with exfat but having some issues, after the format when I create a file the file says it is already created, presumably from a previous format, possibly with regular FAT.Currently calling as stat...
This line:ProtocolStatus->Activity = (StatusReg & FDCAN_PSR_ACT);I think it should be:ProtocolStatus->Activity = ((StatusReg & FDCAN_PSR_ACT) >> FDCAN_PSR_ACT_Pos);I'd appreciate if ST can confirm this.
How to resolve recvfrom() issue on STM32_Network_Library. I'm using stm32H7B3I-DK board.FreeRTOSSTM32_Network_LibraryES_WIFI (BSP) When I tested UDP socket, sendto() was working.But recvfrom() was not working, it was blocked for ES_WIFI_MAX_SO_TIMEOU...
Hello community, I experienced a strange behavior, when when using the UART-DMA-mechanism.The MCU is a STM32L051R6T6, and I use CubeIDE with HAL-drivers.I receive a cyclic telegram of 40 bytes on both USARTs.The telegram starts with two detection byt...
hi,We're using the STM32F7 in our project and would like to flash over USB. In the host application we use USB for data transfer which works well. Unfortunately, I have had no success getting the device into the bootloader as we have no access to the...
Hello?As title, I want to know product with USB, FD-CAN, 2~3 DAC, etc.Problem is USB and HCLK are bound(using external clock), so that upper limit is determined to be low.(48, 96, 144 MHz in maximum 170 MHz)For that reason, to ask the question, is ...
