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...
Hi,we are using a coin cell to supply the internal RTC of an STM32MP157 when our system is unpowered.This works as expected - as long as the external supply is off. As soon as the system is powered on, the battery is discharged with >20µA.Observing t...
I am asking this question after using the the Developer package of the STM32 Echosystem in orfer to recompile the kernel drivers of the ADC to activate the ADC, how ever i can't figure out how to modify the device tree. i was trying to get this examp...
/* USER CODE BEGIN PD */ #define ADC_BUF_LEN 4096 /* USER CODE END PD */ ... /* USER CODE BEGIN PV */ uint16_t adc_buf[ADC_BUF_LEN]; ... /* USER CODE BEGIN 2 */ HAL_ADC_Start_DMA(&hadc2, (uint32_t*)adc_buf, ADC_BUF_LEN);I've got the above code ...
Hi all,I am not familiar with STM32 platform but the DFSDM ADC feature seems to do exactly what I want (external delta-sigma modulator + digital filtering). I bought a STM32MP157C-DK2 board and started playing with it. But, I can't find any working e...
We are trying to use circular DMA to transfer data from ADC1 into a buffer in MCU SRAM using CubeMX-generated code to configure the ADC and DMA. The DMA stream encounters a transfer error on transferring the first item. I have tried clearing the DMA ...
Echo demo application works fine, but when launching ADC example it fails after transferring the elf.Windows host. DK2 board./Peter
Hi,i try to use a ADM DMA with the board in object.I generate the code with CUBE MX and i add only the function HAL_ADC_Start_DMA(&hadc1, (uint32_t*)&buff, 1); before the while loop in the main.After i start the ADC, the hadc1.State remains in HAL_A...
