The wake-up feature of the internal oscillator and USARTs (without data loss) in combination with tiny 3x3 QFN package makes the ATtiny441/841 devices attractive. 4/8 KBytes of internal FLASH memory could be good enough for small applications. Atmel thinks these devices are ideal for cost-effective consumer applications such as computer accessories, thermostats, personal health accessories etc. For what kind of applications you would use these controllers?
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.
