STM32H523RCT7 ADC DMA MULTICHANNEL PROBLEM
Hi ST Team,
Currently i am using STM32H523RCT7 MCU for one of my project. In this MCU, i am facing a problem regarding ADC MULTICHANNEL DMA.
When i am using the 10 adc channel with dma which is trigger by timer3(trigger timing 100us)using below API..
HAL_ADCEx_Calibration_Start(&hadc1, ADC_SINGLE_ENDED);
HAL_ADC_Start_DMA(&hadc1,(uint16_t *)uADCConvertedDataCopy,10);
HAL_TIM_Base_Start_IT(&htim3);
then in main while loop mcu perform instruction execution at very low speed.
When i commnet above API as below..
//HAL_ADCEx_Calibration_Start(&hadc1, ADC_SINGLE_ENDED);
//HAL_ADC_Start_DMA(&hadc1,(uint16_t *)uADCConvertedDataCopy,10);
HAL_TIM_Base_Start_IT(&htim3);
then MCU perform instruction execution at good speed. that means while loop execution faster.
I think their is some issue regarding my cube mx setup or while using the ADC DMA API.
For check the execution time i make a pin high HAL_GPIO_WritePin(GPIOC, GPIO_PIN_9,1);
and do some task & after that make a pin low HAL_GPIO_WritePin(GPIOC, GPIO_PIN_9,0);
Please help me to resolve this issue.
I am sharing the code generated by cubemx with source code.
PFA.
Thanks with Regards,
