We will describe the Smart.JS platform (focusing on parts other than the V7 Javascript interpreter itself, which is the focus of another talk), and give the audience a taste of the embedded development process for two different platforms: one from an established player in the field and an up-and-coming recent entrant, very popular with enthusiasts. We will discuss the hardware, the SDK and the developer interactions, the challenges that we had with each of them and how we tackled them in each case.
