Feedback on Function Generator App Design

(1/2) > >>

aaronsnoswell:
Hi All,

I'm working on a Function Generator App for electronics hobbyists. I'm aware there are several out there that already do this, but I wanted to develop one anyways for fun. I've tried to use the 'flat design' approach that seems to be all the rage at the moment. I'd love to hear your feedback on the features and usability of this design. The screenshot is on Red Pen:

Thanks all

Sweeps?

Harvs:
When you say "app" my guess is you're talking about a phone/tablet?  If so, I thought the outputs were all AC coupled at some point in the signal chain, in which case how are you going to implement the DC part?

Very very good point!

Too bad the outputs generally won't be other than AC coupled, otherwise you could write an open-loop bench supply App ^^'

Thanks all.

Great point Harvs! I didn't even think about that. Yes - planning to target both major phone OS's, with tablet versions later on.

madshaman - I would love to include this feature, but am not sure how it would work from a user interface perspective. Essentially the user would need to specify two separate frequencies, and a time, then the program linearly interpolates between them - right? I'm a relative electronics hobbyist newbie myself - do people ever need to be able to sweep e.g. amplitude or other parameters?
