Impressions of preparations for 38c3: Our setup for validating the rx frequency of the RF-Board via DIO2 pin+ using a loosely coupled frequency generator and an ocilloscope.

Well, I couldn't leave it alone...
The Arduino code now allows triangle waves, up to 1.0MHz (same as square waves), and sine waves up to 12.5MHz.
Also managed to push my Owon VDS1022i to its limits... the sine wave started to look a bit ropey after 5.0MHz, but not bad until then.
The design, updated code and even more pictures are all shared on GitHub too:

Hurrah! My latest project, an Arduino/AD9833 based digital frequency generator, is complete... And it works too 🎉
Impressed with rotary encoders and the AD9833 module. Very pleased with my Owon VDS1022i USB oscilloscope performance!
Design drawn, built. Done ✅
Code written, tested. Done ✅

Following my previous project... A rather disappointing analogue waveform generator, may I introduce you to my latest project - a digital waveform generator.
Working on the overall design, some Arduino code and a Fritzing drawing to accompany it.
This 3.3v/5v module has an AD9833 frequency generator, an MCP41010 digital potentiometer and an AD8051 opamp.
I really enjoy joining hardware and software to make a system.
