re: The 8051 is over 30 years old and still going strong

NO RATINGS
I know it occupies a fond place in many hearts but I have to say that the 8051 was the most horrible thing to program I have come across in 25 years. I did at least two projects with it (a bitbus comms systems for a radio switch and the control processor for a DECT cordless phone spring to mind). I, for one, would be glad to see it consigned to the museum! The 68HC11 was much nicer :-) And, yes, a dual-core Cortex-A9 woudl be overkill for a keycard reader but a Cortex-M0 or M3 would probably fit the bill really nicely! Chris

Another old warhorse that's still going strong is the HC11 family, based on Motorola 6800 (now Freescale). After all, putting a dual core ARM Cortex-A9 in a keycard reader is overkill ... :)

NEXT UPCOMING BROADCAST

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.
