simpleFE – A simple mixed signal front-end

simpleFE is a low cost, fully open-source, mixed-signal front-end. Designed primarily to carry out analog-to-digital and digital-to-analog conversion, simpleFE includes plenty of IO and allows you to create your own signal processing system more quickly, more easily, and more cost-effectively.
