We are currently trying to build a external loader for our application.Our System consists of a STM32H743 and a STM32F427ZIT.For the initial upload of the firmware the DFU interface of the H7 should be used and via a external loader application loade...
I would like to use the Stop3 low-power mode on an STM32U545RE (NUCLEO-U545RE-Q board) and to wake-up the device by the RTC. I have a working example for Stop2 mode for which I largely used the inspiration from the stm32u5 workshop. But when I replac...
Hi Everyone,I have written a firmware which write some meta data in STM32L4 internal flash memory. But sometimes it happens that code gets stuck in a loop while erasing the flash memory. uint32_t UserFunctionForErasingFlash(void) { FLASH_EraseInitT...
Hi!Some time ago I did a post asking for a problem i had with this board used as a USB HID Device for a Midi Keyboard project when i wanted to read the value of a potentiometer with the ADC using DMA and send it as a Control Change command.I solved t...
Hello,I have been trying to read/write into an SD card using the SPI or SDMMC method with Fatfs. I wasn't able to make use of the filex option for file operation which is provided in the STM32u5A9 libraries, since I am using FreeRTOS in my project (a...
I have a project that uses DMA in circular mode, and i've implemented the half and complete interrupts necessary to manage the transfer. I'm using just 2 nodes, and I've noticed that I get a complete interrupt to start the transfer, and then the exp...
Hi,I recently purchased a STM32U5G9J -dk board. When I power up the board, TouchGFX demo application is running.Can you please provide the source code of this demo application.
Hello,I'm using Nucleo-H563ZI Board and trying to use FreeRTOS with LWIP. I am able to find the FreeRTOS software extension for the STM32H5 series (X-CUBE-FREERTOS) and enabled in the .ioc file. Attached the .ioc file for reference.But I'm unable to ...
I want to control GPIO output using DMA and Timer. The target is generating a CLK signal of 1MHz and control PB0 synchronized with the CLK.I am using Nucleo-F411RE as the development board. I have followed the instructions from the forum and configur...
Hi,I am using the STM32H745 and facing the following issue:ADC with DMA1 works fine when the DMA2 block is not reset.ADC with DMA1 fails when the DMA2 block is reset(in RCC->AHB1RSTR). The "DMAMUX request line multiplexer (DMAREQ_ID field in the DMAM...
