Hello,I am working on USB device CDC ACM for STM32N655L0. I found an example about "Ux_Device_CDC_ACM" for NUCLEO-N657X0-Q. Can I use this example for my mcu? How can I find ioc configuration of this example?I also tried to implement this example to ...
Hello everyone! I'm working on a project using an STM32U575 microcontroller, and I need to manage an SD card (read, write, etc.) via SDIO in 1-bit mode, but without using FreeRTOS. I noticed that FatFs is not natively supported for this MCU in STM32...
Hi,Im trying to configure SDMMC 4 wide bus with FATFS for SD card.Im not able to see any DMA options or Platform setting to set SD detect GPIO pin.am I missing something? I have refered through most of the documentation and tutorials online but with ...
Hi,I'm currently using an STM32G0B0CET6 and encountering an issue with writing a uint32_t variable to EEPROM using Write_U32_Variable(). The function works correctly during task initialization and in normal bare metal while loop too, but it fails whe...
I am using two STM32H503 boards. One is programmed as an I3C controller, the other as an I3C target. My goal is to have the target send an IBI on the bus and the controller will receive the IBI and then immediately issue a pended read -- there will...
I am connecting a TCP/IP stack to the HAL_ETH driver of an STM32F7xx. I am using https://github.com/STMicroelectronics/STM32CubeF7/blob/master/Projects/STM32F767ZI-Nucleo/Applications/LwIP/LwIP_HTTP_Server_Netconn_RTOS/Src/ethernetif.c as a starting ...
Hi everyone,I'm building a watchdog application on the STM32 NUCLEO-U385RG-Q using the Arduino IDE and the IWatchdog library. Since the library doesn’t support early interrupt callbacks, I modified it by adding some LL code (afterLL_IWDG_SetReloadCou...
Hi guys,I'm coming from Arduino and recently started working on a project where I need a protocol that supports bidirectional communication between MCUs and Hot-Join.I decided to give I3C with the STM32H5 a shot and got myself some Nucleo-H503RB boar...
Could you please explain why global interrupts are disabled (using __disable_irq()) at the beginning of the LPTIM_Disable() function, and re-enabled at the end?Does this relate to ensuring atomicity during the timer's register save/restore process, p...
On STM32F4, when you choose PLLCLK as the MCO1 source, does the HAL actually routes the PLL output going into SYSCLK, i.e. after the PLLP division?#include <Arduino.h> #include <RCC.h> void SystemClock_Config(void) { RCC_OscInitTypeDef RCC_OscIn...
