This project implements a simple SPI where the loaded 16b data can be output in 8b chunks (high and low byte). In addition, a magic cookie detection is implemented (an output goes active on detection of 0xCAFE).
In addition, a first- and second-order delta-sigma modulator is implemented create a simple low-frequency voltage output with 16b.
Further, a sine generator with programmable frequency can be used to drive the DS-modulator.
The input and output list documentation can be found in info.yaml.
