    DMA Transfer between Filter and SRAM

    umamashireen_2047871

      Hi,
      We are trying to acheive something like Sigma-Delta ADC -> DMA -> Filter_Block -> DMA -> SRAM. Initially we started testing
      with ADC -> DMA -> Filter_Block-> Interrupt. The readings obtained were as expected. However when we tried replacing the 
      interrupt with DMA {Sigma-Delta ADC -> DMA -> Filter_Block -> DMA -> SRAM} we noticed the readings not as expected. 
      For the 50 tap filter the readings kept changing till the 49th sample and then it remained constant. 
      I have attached the project bundle. Kindly help me figure out the issue ?

         

       

         

      Thanks
