XR2206 function generator

The heart of the sinneb 6v (really, really have to come up with another prototype name). For now one xr2206 function generator produces the base waveshapes for the 6v. The xr2206 is, according to the datasheet, capable of producing high quality sine, square, triangle, ramp, and pulse waveforms of high-stability and accuracy. For now I’m only using the sine out, but switching waveforms is definitely something I’m gonna include!
