Small memory footprints will be the lion's share of devices (sensors) placed on the IoT. This requires a significantly different development skill set than can be found in Java EE and Python Apps. For example, a typical SCADA implementation may have 40,000 sensor points. Sheer costs will preclude the use of devices capable of running a full O/S like Linux or Android. The proliferation of ARM Cortex M0/3/4 devices as replacements for 8051/Z80/68HC11 also have limited memory foot prints with no MMU for protection. Anyone remember pointers?
What are the engineering and design challenges in creating successful IoT devices? These devices are usually small, resource-constrained electronics designed to sense, collect, send, and/or interpret data. Some of the devices need to be smart enough to act upon data in real time, 24/7. Are the design challenges the same as with embedded systems, but with a little developer- and IT-skills added in? What do engineers need to know? Rick Merritt talks with two experts about the tools and best options for designing IoT devices in 2016. Specifically the guests will discuss sensors, security, and lessons from IoT deployments.
