Join Michael Lehman for an in-depth discussion in this video Creating command and control, part of Android App Development: Internet of Things.
- Let's talk about creating…the command and control component.…The command and control component…has to have three separate things:…a CPU for making some kind of calculations…and controlling the communication device…and gathering data from the sensors…or passing commands to the effectors,…some kind of memory to store…the current status of the device,…and to store the program that the CPU is running,…and most likely one or more timers.…There are some kinds of things…that don't have a time component to them,…for example, "What's the current temperature?"…or perhaps, "What's the moisture content of the soil?"…But in most things, there's gonna be…some kind of time component as well…or some desire to be able to change an effector over time…and therefore a timer is very crucial.…
For the CPU in a thing, it's gonna be a low power device,…probably gonna be 10 percent of a desktop CPU or less,…and probably an ARM, or similar, low power instruction set,…although Intel is now starting to make inroads…into creating x86-based instruction sets…
