@Rich, the Verizon facility is for devices that use Verizon's network for connectivity and that includes IP. They have a test lab where companies can sign up for free testing with Verizon's network. Impressive place.
About security and IoT, Green Hills is pushing out their RTOS on phones to run 2 or more Android operating systems so you have the work OS and the personal OS on the same phone. They say it's military-grade. I wonder if the security can be done with a real-time operating system.
Speaking of prcessing power, I've been speaking with people about things like LTE-A, 802.11ac and the MIMO and beamforming technologies that are being used. The processing power needed is mind boggling.
Duane, the processor power is what allows the processing overhead to be tolerable. Some of the thinking is that the kinds of optimizations we have to do for 8-bit are simply an impediment to fast time to market, which is the driver for the IoT it seems.
It will be ineteresting to see if such standards add much to the processing overhead. I don't think the "death of 8-bit" issues has come close to being concluded yet, but as more processing overhead gets thrown in, the issue may become moot.
Measurement - My plan is to convert everything to I2C. All of the analog sensors will get put on a tiny MCU board. That way I'll have a variety of different sensors all using the same interface. I'll put a bunch of I2C interefaces in the FPGA and talk with all of the sensors simultaneously. That's my plan, anyway. Whetherr I manage to implement it might be another story.
Susan, yes it offloads the main chip, especially for things like calibration and compensation. Just saw a press release on a llibrary of functions for turning a magnetometer reading into a reliable compass. More complex than you might at first think.
max, it was a little more involved. The presentatoin talked about combing information from multiple sensors to overcome the limitations of individual sensors. Tilt to correct magnetic compass. accelerometer to detect when gyro drift is occurring. That kind of thing.
The show floor looked very well attended. I thought the Linaro hacker conference was interesting. All these rooms were set aside for programmers from different companies to go in, hack, and solve some issues in the code that they could all then share.
Max has passed the torch to Martin Rowe and me for handling these weekly live chats. (No comment on it taking two of us to fill his shoes, though I will admit they are at least a 13E.) This week's chat will be a bit earlier than usual (9am Pacific time) because I will be returning from ARM TechCon and boarding a plane at 10.
Speaking of ARM TechCon, that is the subject of this week's chat. Lots of activity here in one of the top-tier trade shows in the industry. EETimes will have covered the news announcements, but no one can cover everything. Here's a chance to discuss the show as a whole, put the announcements into perspective, and share what you found on the show floor (or ask those who were there what they saw).
Come join us at 9am Pacific for a live chat wrapping up ARM TechCon!
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.
