DrFPGA: wind river has built an embedded hypervisor(which is a pretty good way to secure applications against malware) , in 10K lines of code. I don't know what micruim has, but lines of code is not a good way to judge it.
@Rick, the growth numbers for Micrium were interesting. Do you know if they are from developers moving up from programming to bare metal or dropping back from more-complex Linux environments? My bet would be on the former.
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.
