Recap In Part 1, we covered PCM audio and superimposing waveforms, and developed an algorithm to combine an arbitrary number of audio streams into one. Now we need to use these ideas to finish a full implementation using Qt Multimedia.

Choosing Your Embedded Hardware

by Nathan Collins

Choosing the right hardware for an embedded Linux device is so much more important than your software choices. Making the wrong decision can lead to significant costs and disruptions if you have to change hardware mid-development. Read this blog first before you solidify your choice.

Choosing a Screen for Your Embedded Product

by Nathan Collins

Not all devices require screens. Some rely on web-based user interfaces or smartphone apps for control and interaction. But if your product needs a built-in screen and you need to decide which to get and what to do with it, the rest of this blog is for you.
