“Build a function generator with an ATtiny3216 micro, a AD9833 Programmable Waveform Generator and digitally controlled amplitude.
Recently I built a function generator based around a AD9833 module. In that project I used the blue variant. This is the basic module and just holds the AD9833 and 25MHz crystal clock. At the same time I also bought the green variant but I couldn’t find any schematics or code examples on how to use it. It also includes a MCP41010 digital potentiometer and AD8051 high speed, rail-to-rail amplifier.”
