Hi all, i am planning on making an adapter board to use SD cards as a storage media for ipod classics which uses IDE hard drive. I will be using stm32f407 (512kb) for the development works. And yes i looked around and there seems to be no ic currentl...
Hi all!Environment: I use MX to configure the DCMI Peripheral including DMA!MX generates MX_DMA_Init() and MX_DCMI_Init()After DCMI initialization in main with the above mentioned functions I use the functions HAL_DMA_RegisterCallback(&hdma_dcmi, HAL...
Hello,I'd like to setup a DMA transfer to feed a SPI Display with 8192 bytes per DMA cycle. To offload the MP1 I want to do this with the help of the M4 coprocessor. For my tests I am using the CubeIDE and a custom board. As a basis for learning I tr...
On a proprietary board based on STM32MP157AAA, code was created on the M4 core for reading 11 analog gates managed in DMA (end of sequence interrupt) of ADC1 and ADC2 in independent mode with conversion start via software executed cyclically. The adc...
First I declare the buffer length/* USER CODE BEGIN PD */ #define ADC_BUF_LEN 10000Then I declare the buffer/* USER CODE BEGIN PV */ GPIO_InitTypeDef gpio_init_structure; VIRT_UART_HandleTypeDef huart0; VIRT_UART_HandleTypeDef huart1; uint16_t a...
Hi,I have a problem with the DMA seemingly being shut down due to ADC overrun.What I want to achieve: Three ADC channels should be read indefinitely and the values should be written to memory by DMA as soon as they are ready.What's currently happenin...
There seems to be an option to change assignment in STM32CubeIDE (in .ioc file), but DMA1 is assigned to A7 and DMA2 is assigned to M4 and the another core is always greyed out. Is it possible to unlock those settings?
Hello,actually, our processor STM32MP153 (dual core) is completely full with the "normal" memory regions regarding the MCUs (M4) code and data. So now, we decided to add the RETRAM_data form ORIGIN = 0x00001000, LENGTH = 0x0000F000 /*60k*/The linker ...
Hi,We are using Stm32mp157a processor in my custom board.We are trying to work on dac with DMA but it is not working.You can see my configurations below.In cube mx for DAC there is no Dma option.so we added DMA manually with reference Stm32mp1 Uart ...
