SO in assembly there are specific op codes that are used when the FPU is enabled versus emulated when not. So unless you write in asembly, it will be hard for the C compiiler to do this. There are specfic exceptions and ISR for the FPU, you can monitor those. These are explained in the App note for the FPU at www.st.com/stm32f4.
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.
