Hello, trying to get DMA transfer to work.This does work fine: //INIT DMA static void MX_DMA_Init(void) { /* DMA controller clock enable */ __HAL_RCC_DMA1_CLK_ENABLE(); /* Configure DMA request hdma_memtomem_dma1_stream1 on DMA1_Stream1 *...
hello everyone,how can I solve this problem, I'm stucking here, I can't understand where is the problem, this error is duplicated 4 timesthank you
hi dear.I built a custom board based on the Stm32f796i-discovery Board.I am trying to link TouchGFX but I can not write image to External Flash Memory (MX25L5124G).The MX25L512G_STM32F769I-DISCO.stldr file is located in the External Loader folder of ...
Hi,I'm working with DMA on an STM32F745. I have enabled a DMA interrupt for Transfer Complete on SPI RX, when the data is ready to be read. To do this, I set the TCIE bit in the DMA_SCR register. In the interrupt routine I read the data and I disable...
Hi all,from last 8 yrs i am writing programs for microcontrollers (mostly project on microchip, st) 8 bit/ 32 bit.i always write programs by writing directly to the registers. i never used any library like SPL, HAL, LL doesn't matter how long the cod...
Dear all, I am working on FDCAN with Nucleo STM32G474RE. And I cannot receive any messages...Unfortunately I cannot find any examples for this board.I am able to send messages from the board and receive it on PCAN tool.Unfortunately when I send messa...
I'm using DISCO Board STM32F769I and use SDRAM in my application applicationi note that when i write data more than 1023Byte the data is written in the next bytes as expected and also over write from the start of SDRAM (0xC0000000)if there is any con...
This post: https://community.intel.com/t5/Intel-Makers/Low-Voltage-Signaling-SD-Cards/td-p/490563 seems to imply that newer SD cards can operate directly at 1.8V with no translation to 3.3V. Can anyone confirm if STM32H743 supports this?If so, does t...
Hi,I am using STM32G474 with TIM1, TIM8 and TIM20 and working with STM32CubeIDE.I want to updatethe ARR, CCR1, CCR2 and CCR3 regs at the same time. I taught that with the preload register it can be done but it doesn't work for me.So how can I do to s...
Hi All,I am having trouble with DMA transfers using a F429.I am using DMA1, Channel2, Stream6 - regulated by TIM4 Updates.It is a memory to perpheral, 32 bit, single transfer, double buffer Off - from Flash (AHB3) to GPIOG (AHB1).However, it breaks o...
