Ask questions and find answers on STM32Cube packages, including HAL, LL and middleware, and expansion software.
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...
In ethernet HAL driver stm32h7xx_hal_eth.c function void ETH_DMARxDescListInit include row: " WRITE_REG(heth->Instance->DMACRDTPR, ((uint32_t)(heth->Init.RxDesc + (((uint32_t)(ETH_RX_DESC_CNT - 1))*sizeof(ETH_DMADescTypeDef)))));"This code adding val...
i used lvgl and stm32f469i-disco and i got many error Error: L6406E: No space in execution regions with .ANY selector matching. i turn off all the file system (stdio,win32,fatfs) because i have no external library (ex. dirent.h and unistd.h forlv_use...
I want to create a power distribution system that can accept up to three supplied (AC/DC, USB, and Battery. At the end of VBUS will be the management system that will choose the highest voltage and use that as primary supply.Would like some suggestio...
The Question (since this is a little long): Is there any known interaction between the WWDG timer and the bootloader located in System Memory? Is there any known differences in the F405 revisions that could have an interaction between the WWDG and b...
Hi, I want to use STM32 Nucleo example "STM32F072_MB1303_DRP_SRCING_DEVICE" on my board that include 1x STUSB1602 + 1x STM32F072CBU6 (48-UFQFPN).(the example works with STUSB1602 + STM32F072RB (LQFP64))-What will be the easiest way to port the examp...
The description for HAL_GetTickFreq says/** * @brief Return tick frequency. * @retval tick period in Hz */It returns 1 when the tick frequency is 1kHz. The period would be .001 seconds and the frequency would be 1000 Hz. Based on the typedef below, I...
I'm developing a device that works as a modbus slave over TCP/IP. For this application I'm using FreeRTOS with CMSIS-v1 and LwIP. The problem occurs sometimes when I disconnect the master (a PC with modbus poll), then the code stucks waiting for a se...
i had USB Host MSC working on H743 (devE board) , read USB sticks 1...64 GB without problem;now, after try to make USB Audio Host on second (HS) usb port, which is not running until now (there is no working example by STM - and no plan to do this (!)...
Hi,I'm using OTG HS, in device mode, as a CDC VCP. It works when "Internal IP DMA" is disabled. If I enable DMA, the USB device enumerates but CDC_Transmit_HS() no longer works.I saw the article on USB DMA with the STM32H7, and I tried similar things...
