Long post about wanting to sell function generators.. but no link to buy?
It’s a first step in a learning project, not a product. They say as much in the article.
You are correct! I'm a professional EE by trade during the day.
I've had a lot of fun on this first pass learning about direct digital synthesis, STM32 microcontrollers, and serial consoles. The next revision, which I'm just beginning to work on, will feature a whole nother batch of electronic concepts I'm interested in. Small sampling of what I expect to learn about next inlcudes: chebyshev filters, error budgets, and multistaged opamp design.
