Been trying to get an test application working on a STM32F469NIH Discovery board.Should be fairly simple - Write a file to the SD Card, with FatFS, the read back:Try as I might, I couldn't get things working.After a bit of debugging, I think the issu...
Good day!I am using stm32h7 with USB3300. For firm use CUBE MX 5.6.1. USB HS CDC VPC class USB with USB DMA Disable - everything works.As soon as I turn on USB DMA Enable, the device is no longer detected by the PC enumerating failed. Please tell me ...
Posted on May 26, 2017 at 06:18 Hello, I am using STM32F411RET6 chip to access uSD card with SDIO 4bit. By default it uses polling mode to read/write data with SDIO, such asBSP_SD_ReadBlocks(). The problem is that I want to continuously wri...
Hello,I have developed a code in FreeRTOS mode that contains two main tasks. The first one check if I have received an RX buffer on the I2C bus, and the second one manage the data that has been received.However, after receiving the first buffer, I am...
hello,trying to write to a ST25DV tag mailbox, via I2C with DMA.The chip has a mailbox of 256 bytes.I use the function:HAL_I2C_Mem_Write_DMA When I try to write data of size 256 bytes, only 255 is written and the last one is written to 0.Writing 25...
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...
