I am relatively new to programming, and just discovered the PSOC line. Let me say...these IC's look awesome! I have quite a few applications that I have been playing around with in my head for quite some time, and the PSOC line seems like a perfect fit!
Anyways, I have just ordered an evaluation board, and am now reading through the documentation of each block. Is it possible to adjust the filter cutoff frequency in real time? I am working on an audio application (compressor) and would like to have variable 2nd order butterworth high and low pass filters in the sidechain. Would this be possible? I have read the documentation and do not see anything implying that it can be adjusted in real time, but may have missed something. If the filter cuttoff cannot be adjusted in real time, what are the work arounds? I would REALLY like to use these IC's as an all-in-one solution. 😄
Nathan, I suggest doing a Google (or other) search for The Filter Wizard who is Kendall Castor-Perry. He has a blog on Cypress for all things about filters -- FIR, IIR, time aligning multiplexed inputs. You will find a fantastic filter education with him. The short answer to your question is YES you can do the cutoff in real time -- even with multiple input channels at audio frequencies. You can also do a search for The Filter Wizard in this Cypress Community window. Jerry
