All of the STM32 family is single core today. The minimum high end CPU frequency is 32MHz. So most operations can be handled by a single core processor. With dynamic clocking, you have the ability to control power based on CPU frequency including sleep and stop states. Much easier than to synchronize two processors.
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.
