EEVblog #642 - TI Connected Launchpad

Dave checks out the $20 TI EK-TM4C1294XL Tiva C Series TM4C1294 Connected Launchpad Internet of Things.
ARM Cortex M4 processor with Ethernet and IoT demo application.
How useful is it out of the box?

I would assume the event was checking if the value was == 1. If you press it again, then it becomes a 2 and so the event is no longer active. The alert would be for when the event is triggered (the first button press), so you would need to reset the button counter before it was possible to trigger again.

I like that anchorman style shooting position at the start. Good use of the free standing table.

Hey Dave!
The User SW is a counter that counts the number of presses. You set the event to be true when that counter is 1. If you press it again, it will be 2...3 etc. thus your event will change to false.

[BaratheonBC]

it seemed that the event didn't fire because the switch1 variable has a press counter and you were comparing it to 1 (as in true?), so it may be possible to fire the event on value change, or something that would detect the counter rising

Great vid, the camera across the bench worked just fine.

TI makes these great little development boards and sells them for makers to use practically at cost. We've used them in numerous rocketry projects. It seems like all the frustration you had with this kit could be attributed to crappy Exosite junk software. They're not doing TI any favors if their demo application is so buggy.

The new set looks fun?  Miss the scopes, and equipment.  Do yourself a favor and point a light at the back of your head.. It's called a "hair light" and will separate you from the background (source =  I'm a video editor/producer)

I'm glad I suggested an island bench now, it does look more natural and convenient to demo stuff that way :)  I would suggest wearing a lighter t-shirt against the dark background though, and maybe a pull-down neutral grey screen behind you? Failing that, put more gear on the rack shelves to lighten the background.

the best embedded c programming tutorial and it uses the TI Embedded Systems Programming Lesson 0: Getting Started

Considering people might connect some really dangerous things to these boards, having a secure passwords is a must...

15:30 I've read that Perth and Brisbane timezones do not observe DST, while Sydney (and other Australian timezones) do, so that may be why you can only select those.

I will never buy any of these "internet of things" thingies, that don't provide the possibility to run your own server. If the manufacturer decides to shut down (or is forced to because going out of business) the service, you can throw out all your stuff.

Loving the new intro dave, looks good!

[michaelwalker]

Another great vid Dave! Regarding the events, my guess would be they are single shot so the moment the button presses hit 1 they trigger then disable themselves. You'll probably find if you set that constant to 5 you'll need to hit the button 5 times before they triggered then disabled.

Hi.
I tried  to register  the Arduino   Ethernet   board through windows XP and I flunked.I registered the Arduino board it self though made some easy circuits.But with the internet I could do the way more!Thank you for any suggestion.

Can it be used to control a device, e.g., have it respond to a motion detector, and then it alerts you, thus prompting you too access your IP cam, and if an unauthorized person is in there, you can have a special canister and sprayer that sprays sulfur trioxide at the person.

[randomnickname]

Wow, new bench looks much better. I like it :)

[jerzyk]

maybe this "Alert Interval" - you had set it to 0 (zero) - no repeat, and it disables it after first one?

Beautiful website and professional product from Texas.

That +3.3V jumper JP3 isolates the 5V to 3.3V regulator (U5, TPS73733) output from the 3.3V rail. Nothing on the board requires 5V, it all runs on 3.3V, so if you supply 3.3V directly from pin 1 on the X11 connector (the big 98-pin one down the side) or pin 1 on one of the booster pack connectors (X6 or X8), you don't need a 5V supply at all.
