Dear STM32 Community, We believe that the example projects provided for the STM32Cube embedded software are a valuable resource when developing projects. We would like to better understand how developers use these examples in their workflow and e...
I have a STM32 based device which switches on command from a USB/CDC device to a USB/MSC device. What I need now is a way to switch the STM32 based device back to USB/CDC. I see where the SCSI Eject command is processed and reported by the STMicro d...
Hi, i have stm32f446ze on my custom pcb. Pin details : PC8 SDIO_D0PC9 SDIO_D1PC10 SDIO_D2PC11 SDIO_D3PC12 SDIO_CKPD2 SDIO_CMDGlobal interrupts enabled and no DMA. i tried with Cubemx version 6.0.1, 4.25.0, 4.26.0. but whole the time , f_mount gave ...
Trying to use osThreadFlagsWait() in my command handler for command processing thread to save CPU utilization and seeing issue where system gets stall.====================while (1) { int cnt = getcmd(); if (cnt >= 0) { process_command(); } else...
Hello. I've been using the ST USBPD code for a few years for a variety of products. The default timer seems to always be Timer 2 (32 bit). Recently I've got this working as expected with an STM32G0 using Timer 2. However, this product switched to the...
Hi,I am developing a IO-Link device and I am using the P-NUCLEO-IOD01A kit demo. The IO-Link works fine. Now I need to use a serial communication to receive a frame from another device. For this I use USART2. I use the example "UART_HyperTerminal_TxP...
Hello. I am trying to access SDMMC1 peripheral via Cortex-M4 core. I access SDMMC with no problem when I configure sdmmc clock 15MHZ or lower. Also fatfs use_dma_template option is disabled. But I have to use FreeRTOS in my project. So when i enable ...
Hi Everyone, i'm using two boards for my hobby purpose(stm32f108cxx bluepill board and stm32f407g discovery board). i tried the controller area network loopback mode in bluepill is working fine but in the stm32f407 discovery board c...
Hello, I have been trying to program a custom board. I am using the stm32f042k6t7 chip and I have been working on this for a few weeks now. I've got my board double checked and even ordered another V2Link thinking it might be that connector. I hav...
Hi guys,I'm currently working on a project where I need to use the SPI protocol. After setting everything up in the .ioc file and generating the code. I wanted to check if the clock signal was properly working. So i hooked up my ossciloscop to the cl...
Dear All,I'm using stm32G0 MCU for battery operated application and I2C, UART and RTC and GPIO are using I want know What should be peripheral state before going to STOP mode mean "should be deinit before going to stop mode or leave it as it is and ...
