DMA can reach all the peripherals and memory as well as the Cortex Core. It is best to consult the reference manual for the granularity of exactly how to connect each DMA channel to each peripheral/memory.
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.
