I am new in the daisy seed forum and making projects.
I just wanted to start using the simple library examples, but I cannot find in the DSP library a module for first order low pass filters (LPF) so I can set up its frequency cutoff. I could not find a first order high pass filter neither.
I could implement my user level function for LPF but the whole idea of daisy is that it has many things already done and I think the first order filters must be somewhere maybe in another library (not the DSP one), maybe with a name that doesn’t remind me what i need.
By the way, I want to make a frequency glider so given notes changes, an exponential frequency change is heard
where I can find these first order filters?
