We received 10 AVR-IoT WG Development Boards as giveaways for AVRFreaks.

 

What crazy things would you build with your free AVR-IoT WG board? Comment below, by Dec 11,  for a chance to win! 

 

The AVR-IoT WG board uses an AVR MCU, more specifically the ATmega4808, a CryptoAuthentication device and a Wi-Fi module. It can be powered from USB or a battery, which is not included, since it is a pain to ship Li-Ion batteries...  

 

avriot

This board demonstrates how easy it is to set up a secure connection to Google's Cloud IoT Core platform and pump data to the cloud. You do not need to worry about the Wi-Fi stack as it runs on the Wi-Fi module, and the unique certificates are preinstalled on the crypto chip. Sweet!

 

The board also contains temperature and light sensors. By default the data from the two sensors are securely sent to the cloud and will be displayed live on a web page, unique to the board that you use. So you will see your data, but nobody else can. With the fast fingers and mind of a true AVRfreak you can have the connection established and see your data in less than 30 seconds… perhaps… let's get your fastest time wink

 

Good Luck !

I've always wanted to build some kind of monitoring system for my house; temperatures, water flow and pressure of the district heating system and temperature inflow and return (energy consumption), pressure of the freshwater, outside temperature, humidity inside and out, wind speed and direction, rain etc. etc.

 

I was actually planning on building some kind of PLC system to collect the data, but I might be inclined to something like this if I can easily have it on-line accessible.

 

Possibly it could be interesting at my job too (automation), but I might have a hard time convincing my boss to let me spend hours developing something from it! frown

We have an idea of collecting different data for our customers and presenting them in some kind of cloud solution, the challenge though, is that the data is partly already available in existing PLC solutions and it would be "easier" just to grab it with the existing PLC or at least it will be less labor intensive implementing it in a new PLC, however getting it from the PLC to the cloud is the challenge.

This looks like a nice board for prototyping and producing PoCs. 

 

Having had more of a look, I have an application where this would be ideal for the PoC. IoT application in Trading Room, don't want to say too much more.

 

Yes please!!!

Neat board.  Wouldn't mind playing around with one.  To be honest though, I likely wouldn't ever use it with cloud-based services of any kind.  I'm more likely to use it to develop/prototype non-cloud, closed-circuit applications, like wirelessly controlled props and lighting effects for stage.  Perhaps a home power/voltage monitor.

Wow!

 

Thank you for thinking of the AVRFreaks gang.

 

Unfortunately, neither Bascom nor ZBasic support the 4808 (yet?), and I just don't have time to learn C right now, otherwise I'd throw my hat in the ring.

 

Interestingly, just this past weekend I spent 4 hours (oh my aching back, knees, hands, etc), on the roof installing a Main's powered heating cord to prevent ice and snow build up.

 

I was thinking of putting a ESP8266 / XmegaE5 board outside to send me an internet accessible indicator of when the heater is on or off.

Heck, once one has the link, one could easily make it a IOT bi-directional control, and turn it on and off from my phone, etc.

 

This would be a great little board for that project, unfortunately I don't have the skills required to program it.

Darn! I have an application, a good one. Design really is likely to use an M48xx device. WiFi is one of several planned access ports, others including LoRa, BTLE, and various wired systems. Would love to get my hands on something that provides a WiFi stack in the WiFi device. 

 

Please add my name to the list!

Oh no. Nononono. Stop..... Don't tempt me. Nooooo, I don't have time for another interesting board. I have plenty of other projects, and not nearly enough time.
Please do NOT pick me. I don't want it.

My garage lighting is controlled by a mega162 and a 28j60 ethernet chip. It's time for an update!

It did four channels of frequency locked phase control. At 8MHz, the ‘162 was working hard and some hand crafted asm was used. Extra cpu performance and peripherals might eliminate the need for asm.

Hello.

I have a project in mind that would probably suit this dev board. I think it might be very simple in terms of electronics and programming but also requires some hand made objects to be built.

It's a frequency controlled wind blower to avoid smoke coming out of the fireplace. Then it would be controlled either by phone (wireless) or by a remote control or even from a web page.

In terms of electronic stuff, the project would need sensors for temperature, particles (to detect smoke, I really don't know how to detect smoke), a pwm system to generate the desired frequency and I think it's all.

Throwing my hat into the ring also, but like others I can do without 'the cloud'.  I'd be happy just to have my own WiFi LAN, if I can enforce rules that any device will NEVER connect to anything else, and any device not explicitly permitted is denied.  Looks like fun, though!  S.

Anyway, now it is time to get out of my XMega bubble I've been in for the last several years, and have a closer look at this Mega4808 thing. I know I am not going to break any speed records, as just typing in my wifi password will take longer than 30 seconds.

Given the 'cloud' nature of these things, I wonder if we should have a competition to see who two can get their boards to communicate with each other over the net first...

 

Although I'm afraid a 'hunting for AVR IOT Things' algorithm would make my (satellite) internet connection very unhappy.  S.

I haven't received my board yet, but I think I already spotted a mistake in the documentation / picture?

However in the Technical summary, where you can also find the same illustration, you find this on page 13:

I've been looking into the IoT ("idiot?") field recently.   It seems that for about $3 you can now get an combination 80MHz 32-bit 64K flash microcontroller coupled with an internal TCP/ICP stack that includes all the hardware needed for WiFi: https://www.ebay.com/itm/NEW-Nod...

 

As far as I can tell, there are two ways to develop an application for this ESP device.  There is an interpreted script language called Lua that is included in the ESP, and there is an Arduino implementation (that the developer has to install into the ESP), which allows programming in the C++ language and use of most Arduino downloadable libraries.  I don't have an ESP device, so I don't know how much of all this is simply "exuberance" generated by various Marketing departments.  My inner spider sense tells me that this entire ESP thing is probably extremely difficult for an ordinary Muggle to get any specific application working productively.

 

The $29 AVR-Iot-WG (really, you guys should just call it "the AVR Idiot!", but I'll just call it the Avriot) seems to be (after a brief review of the web information) an 8-bit CPU combined with a WiFi stack.  The Avriot has a built-in path for easy data storage and a hardware-based CPU debugging system.  That, plus a lot of support from Microchip/Atmel Field Support Engineers.  For an unspecified fee, the data generated from the Avriot can be stored on Google's "Cloud".

 

The "Cloud", as I understand it, is a pair of giant warehouses packed to the roof with ultra-high-density hard-drives.  From what I know, there are two physical locations of the Cloud, both in central Oregon USA.  The Amazon Cloud is in The Dallas, Oregon (yes that's its official name) and the Google Cloud is in Prineville, Oregon (about 100 miles south of The Dallas).  The Cloud is located here because there is abundant cheap hydro-based electricity, an intersection of the major Internet intercontinental fiber-optic cables, and the connection between two of the main automobile/truck highway systems of the USA (the West Coast I-5 highway and the East/West I-84 highway).  Plus the weather's nice, the school's are good, the food is cheap, and the girls are pretty.  Nerd heaven.

 

So tell me what I'm missing...

Seems like you've formed an opinion!   :-)

 

I too am skeptical about the IoT craze, so what are

your reasons for calling it idiotic?  I'll refrain from

listing my own so as not to bias the response.

Calling IoT "idiot" has nothing to do with any opinion or observation on the basic technology.  It's based solely on the notion that the only word in English that has the letters 'I', 'o', and 'T' remotely close together in that specific order is the word "idiot".  Which is what any native speaker of English is going to see when presented with combination of letters: 'IoT'.

 

And how is this supposed to be pronounced anyway?  With a tripthong: 'eye - ah-t'?  or do we bang out the letters: 'eye' 'oh' 'tee'?

Hi

 

Are your boards hot while working? I found the original demo program is consuming a lot of power, don't know why. When I uploaded my own program (just simple UART messages) the board is cold.

 

One more - do you understand source code of demo app? I was shocked when I saw that "demo for beginners" consists of hundreds of source files. Official PDF explains only everything that is obvious. The most mysterious thing for me is ATECC608. Do I realy need to sing NDA to get a datasheet of an IC in a demo board? Realy?

Hi...

 

Indeed. I also was amazed with the amount of code for a so called "Demo Project". I still haven't found the way to do anything with it due to other reasons but I think I'll struggle a bit to do anything with the board! Anyways, I hope to be able to start with it!

Hi all,

 

Electromaker.io has just launched a Microchip AVR-IoT WG design contest.

Might be of interest to those of you that are planning on building an interesting project with your new board:

The board does run quite warm with the demo program - enough to make the temperature measurement fairly useless as it reads probably 6 or 7 degrees celsius higher than ambient.

Well, I haven't really been working with C programming in a while and it seems like the mega-0 series contain quite a few changes in comparison to the old AVR megas. And also, I'm rusty! What's more is I didn't really do that much in the AVR mega before and it's more than 6 years ago now surprise (I did bunch of different brands)

 

Does anyone have a link to a resource about programming the mega-0 series in C?

Every time i google something it comes up with solutions for the regular AVR mega, probably because the 0-series is still pretty new.

 

It took me at least a couple of hours to figure out how to write a port pin, read a port pin and enable the pull-ups (and enable the invert bit (but at least I got that part down now))!
I like the board for the debugger, although it took me a while to figure out exactly how. But I feel like it's a pretty slow process from here unless I can find some more examples or maybe a homepage, guide or maybe even a book?

Hello all

 

I'm working hardly on understanding the ACR-IoT demo board. Actually I'm working on ATECC608 and trying to develop my own library, because Atmels CryptoAuthLib is so complicated I can't get started with the basics. Moreover, something as easy as I2C is overcomplicated in this example. I don't get how this library connects to I2C hardware. Are there any tutorials how to start with this? PDFs from Microchip's site explain everything that is obvious and nothing more :/

 

Questions:

- How can I send a GET or POST to a ordinary webserver, instead of MQTT with Google Clound? 

- ATECC608 is locked. This device is once-lockable, so it's config can't be changed and many slots (for keys, certs, etc) are locked too. Is this device usable to anything else than Google Cloud, for example Amazon AWS?

 

 

Hilarious - I've found that WiFi network name and password are stored in ATmega4808's EEPROM as a plaintext! Quite funny, while the most advanced cryptographic processor is on the board, isn't it? :)

If the device still work with its peripheral devices even wifi connection lost but power driven to it.

I want to use this board to collect data in my IOT project.

Of course. Its "just" a microcontroller with a radio. You control how it behaves with the program you put into it.
