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!
Solved! Go to Solution.

James,
One way to circumvent signed/unsigned issue with Filter-DMA-VDAC8 is to use extra logic in between, see for example this thread and example project in #7:
Class D adcDelSig>Filter>Pwm using DMA only
I will take a look again, maybe there is some other trick to directly DMA that I missed.
