    FIR filter example is not working on CY8CKIT-059

    jawe_293101

      I am trying to implement the example filter code for the cy8ckit-059,  according to this video:  http://www.cypress.com/video-library/PSoC/how-create-analog-filter-psoc-5lp/385626

       

      Everything seems fine- all components updated, no errors,  but no signal output of the VDAC.  There is something wrong with the DMA implementation I think.  The circuit looks like below.  Attached is the workspace bundle.  

      I also tried to probe the eoc output of the ADC,  but there's no signal.  Is it because this is meant only for DMA ?  

       

      Thanks in advance!
