I'm trying to get SAI working with DMA on a NUCLEO-U575ZI-Q but have not been successful.I've tried using both standard request mode and linked-list mode, but the DMA configuration code is never generated.On an older STM32L4 project, the bottom of `H...
Hi all,I am trying to write to SD Card through SDIO interface with DMA (1 data line) on a STM32F4 MCU on a custom made board. Configuration is done by CubeMX.When writing to one file at a rate of 200kBytes every 10 seconds, after some time (one minut...
Posted on October 22, 2017 at 16:13I want to use ' HAL_UART_Transmit_DMA(); ' to send data in DMA mode like this : char str_Hello[]='Hello\n'; HAL_UART_Transmit_DMA(&huart1,(unsigned char *)str_Hello,strlen(str_Hello)); HAL_Delay(500);But ...
Dear all,I try to read out ADC-Data, that is streamed from an external adc (AD7768) out to the uC. What I want to do is to more or less directly stream out the data via USB CDC.Therefore, I planned to use the DMA between the SPI and USB. However, thi...
Hi everyone!I'm trying to transmit some data using SPI2 on a NUCLEO-H743ZI board (only TX). To do it fast I'm using DMA with HAL_SPI_Transmit_DMA(), but it returns with an error (from line 1465 in stm32h7xx_hal_spi.c):/* Packing mode management is en...
Hello,I need to transfer more data, than I could afford to store in memory with an SPI Master. So I thought to use the circular DMA to update the data using HAL_SPI_TxHalfCpltCallback and HAL_SPI_TxCpltCallback.But how can I stop the SPI transmission...
Hello,I'm trying to send some data via UART and DMA on a STM32F072, but with the low level functions. This works perfectly when using the HAL-function HAL_UART_Transmit_DMA(), but I'm missing some information for the low level functions. I configured...
Hi everyone. I have an issue with USB transmission in DMA mode (USB_OTG_HS, internal PHY, FullSpeed 12MBit/s). I am using a Cube generated project for STM32H743IGT6. If I disable DMA - it works fine. But when I enable DMA USB enumerates on PC and all...
I thought I was the only one wondering how to implement DMA, but it seems to be different. I found this post, and found it interesting how the topic was addressed:To be honest, this was not a post I was planning on at first. However, I was working on...
Hello, I am trying to send ADC data (12 bit) to pc with USB as fast as possible. Now I am using STM32F405 and configured ADC like picture below. Those data of ADC is transfered to the pc by interrupt of DMA which is cirucular mode. And the data trans...
