Question
using stm32h747. I am reading ADC data using SPI on ADS8661 IC. the sampling rate we are able to read at is 14us using FOR loop(PFA). trying to reduce the sampling rate by DMA receive through tim12 trigger, not working, please guide me how to in cube
for(int i=0;i<3000;i++)
{
//__HAL_TIM_SET_COUNTER(&htim4,0);
while(!(GPIOI->IDR &(1<<5))); //monitoring RVS Pin
GPIOI->ODR &= ~(1<<0); // CS pin Low
HAL_SPI_Receive(&hspi2, data_rcv ,2,1); // reading 2 bytes at a time
GPIOI->ODR |= 1<<0; //CS pin high
temp[temp_cnt]=((data_rcv[0]<<8)|data_rcv[1])>>4;
temp_cnt=temp_cnt+1;
// counterCount=TIM4->CNT;
}
