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. Specifically the guests will discuss sensors, security, and lessons from IoT deployments.
