I try to configure ADC + DMA continues cicrcular mode for a H753eval board with CubeMX but with no success.
The example en.stm32cubeh7\STM32Cube_FW_H7_V1.2.0\Projects\STM32H743I_EVAL\Examples\ADC\ADC_DMA_Transfer works perfect but as I have started using cubemx for my other peripherals I would like to stay with cubemx, but I don't get it to work with the ADC+DMA.
Now I have backed to a completely clean project for a 753XI, only configured ADC1_IN0 and RCC(25MHz->400MHz sysclk and 18.75MHz ADC clk).
When I run it as ADC con't mode without DMA
and add the following to my main.c, everything works.
static void MX_GPIO_Init(void);
static void MX_ADC1_Init(void);
adcData = HAL_ADC_GetValue(&hadc1);
But when I change ADC1 config in cubemx to:
added a DMA1 stream0, with circular mode and changed the rows in my code to:
ALIGN_32BYTES (static uint16_t adcData );
and no code in main()
Nothing works! If a check adc.dr register with the debugger it only takes one value at start-up and nothing more.
I've also fiddled with the Conversion Data Management mode as that parameter is a little unclear to me, circular mode is set in the DMA tab as well and the youtube clips I have seen is using older parts/version which doesn't have that setting.
I've also tried for hours to compare the code generated with the one in the Project/__ /Example to find the problem but without success.
using cubemx 4.25.0
Some ideas anyone??
