A Better Battery Arduino

We’ve seen [Johan]’s AA-battery-sized Arduino/battery crossover before, but soon (we hope!) there will be a new version with more MIPS in the same unique form factor! The original Aarduino adhered to classic Arduino part choices and was designed to run as the third “cell” in a 3 cell battery holder to relay temperature readings via a HopeRF RFM69CW. But as [Johan] noticed, it turns out that ARM development tools are cheap now. In some cases very cheap and very open source. So why not update an outstanding design to something with a little more horsepower?

The Aarduino Zero uses the same big PTH battery terminals and follows the same pattern as the original design; the user sticks it in a battery holder for power and it uses an RFM69CW for wireless communication. But now the core is an STM32L052, a neat low power Cortex-M0+ with a little EEPROM onboard. [Johan] has also added a medium size serial flash to facilitate offline data logging or OTA firmware update. Plus there’s a slick new test fixture to go along with it all.

So how do you get one? Well… that’s the rub. It looks like when this was originally posted at the end of 2017 [Johan] was planning to launch a Crowd Supply campaign that hasn’t quite materialized yet. Until that launches the software sources for the Zero are available, and there are always the sources from the original Aarduino to check out.

Who Owns Arduino?

Who owns Arduino? We don’t mean metaphorically — we’d say that’s the community of users and developers who’ve all contributed to this amazing hardware/software ecosystem. We mean literally. Whose chips are on the table? Whose money talks? It looks like it could be ARM!

The Arduino vs Arduino saga “ended” just under a year ago with an out-of-court settlement that created a private holding company part-owned by both parties in the prior dispute over the trademark. And then, [Banzi] and the original founders bought out [Musto]’s shares and took over. That much is known fact.

The murky thing about privately held companies and out-of-court settlements is that all of the details remain private, so we can only guess from outside. We can speculate, however, that buying out half of the Arduino AG wasn’t cheap, and that even pooling all of their resources together, the original founders just didn’t have the scratch to buy [Musto] out. Or as the Arduino website puts it, “In order to make [t]his a reality, we needed a partner that would provide us with the resources to regain full ownership of Arduino as a company… and Arm graciously agreed to support us to complete the operation.” That, and the rest of the Arduino blog post, sure looks like ARM provided some funds to buy back Arduino.

We reached out to [Massimo Banzi] for clarification and he replied:

“Hi arm did not buy nor invest in arduino. The founders + Fabio Violante still own the company. As I wrote in the blog post we are still independent, open source and cross platform.”

We frankly can’t make sense of these conflicting statements, at least regarding whether ARM did or didn’t contribute monetary resources to the deal. ARM has no press release on the deal as we write this.

Announcing a partnership without details isn’t a new activity for Arduino. Recently we wrote about open questions on the Arduino Foundation. [Banzi] was willing to speak with Hackaday at length about that topic, suggesting more details were just weeks away but we have yet to see follow-through on that.

What we can tell is that [Banzi] and Arduino want us to know that they’re still independent. The Arduino post mentions independence and autonomy eight times in a 428-word post. (The lady doth protest too much?) They’re very concerned that we don’t think that they’ve been snapped up by ARM.

And there’s also good reason to believe that Arduino will remain autonomous even if ARM owns a big stake. ARM sells its intellectual property to a number of silicon manufacturers, who then compete fiercely by offering different peripheral sets and power budgets, and they’re very serious about providing them all with a level playing field.

Anyway, the various ARM chips are nice to work with from a hacker perspective. If the AVR-based UNO was the last non-ARM Arduino board ever made, we’d only shed a tiny little tear. On the other hand, if you’re an MSP430 or PIC fanboy or fangirl, we wouldn’t be holding your breath for a light-blue board sporting your favorite silicon but that is just conjecture.

So we have seemingly conflicting information on the details of this deal, but also promises of openness and transparency. On one hand we’re pleased that ARM is the apparent silent partner, but on the other hand we’re left confused and wanting more. Who owns Arduino?

Arduino announces Arm partnership

Dear Arduino Community,

Back in July, we announced that the original Arduino founders regained full control of Arduino as a company. It was the culmination of a project that lasted several months, which required a tremendous amount of effort in finding the right partner that could help us make it happen while keeping the spirit of Arduino true to itself.

Throughout the litigation we dreamed of reclaiming control of the company, bringing it back to its original principles while designing a strategy that would allow us to tackle the challenges of the contemporary IoT world.

In order to make his a reality, we needed a partner that would provide us with the resources to regain full ownership of Arduino as a company while keeping it independent and true to its values of openness.

It wasn’t easy, but more than a year ago, in the middle of the litigation, we started a conversation with an important technology company that is an essential building block of today’s digital world: Arm.

During a very hot day in spring I visited California to meet with Arm. It was a great meeting of minds and we determined that such a partnership was the right fit for us. Arm is an extremely innovative company whose processors can be found inside virtually every mobile device on the planet; but they don’t actually build silicon. Instead, they have created an ecosystem of a thousand-plus partners, some of whom compete with each other, but Arm works in harmony with all of them.

Arm recognized independence as a core value of Arduino. This was very important for us, as it meant full understanding of our need to work with multiple silicon vendors and architectures as long as they make sense for Arduino—without any lock-in with the Arm architecture.

Following the meeting with Arm, I was thrilled. I shared my excitement with our new CEO Fabio Violante and my cofounders: Arduino could again be 100% ours, with the help of a supportive partner that leaves complete autonomy to our team and our community.

We worked very hard for many months to make this happen, and Arm graciously agreed to support us to complete the operation.

What should you expect from us in the future? A stronger Arduino, free to innovate with more firepower, and plenty of enthusiasm for future challenges and opportunities.

We will continue to work with all technology vendors and architectures moving forward. We stay independent; we stay open, and we still provide the most loved microcontroller development platform that has changed the lives of so many people around the world.

A BluePill for Arduino Dependence

Arduinos are helpful but some applications require more than what Arduinos can provide. However, it’s not always easy to make the switch from a developed ecosystem into the abyss that is hardware engineering. [Vadim] noticed this, which prompted him to write a guide to shepherd people on their quest for an Arduino-free environment, one BluePill at a time.

With an extended metaphor comparing Arduino use and physical addiction, [Vadim’s] writing is a joy to read. He chose to focus on the BluePill (aka the next Arduino Killer™) which is a $1.75 ARM board with the form factor of an Arduino Nano. After describing where to get the board and it’s an accompanying programmer, [Vadim] introduces PlatformIO, an alternative to the Arduino IDE. But wait! Before the Arduino die-hards leave, take note that PlatformIO can use all of the “Arduino Language,” so your digitalWrites and analogReads are safe (for now). Like any getting started guide, [Vadim] includes the obligatory blinking an LED program. And, in the end, [Vadim] sets his readers up to be comfortable in the middle ground between Arduino Land and the Wild West.

The debate for/against Arduino has been simmering for quite some time, but most agree that Arduino is a good place to start: it’s simpler and easier than jumping head first. However, at some point, many want to remove their “crippling Arduino dependency” (in the words of [Vadim]) and move on to bigger and better things. If you’re at this point, or still cling to your Uno, swing on over and give Vadim’s post a read. If you’re already in the trenches, head on over and read our posts about the BluePill and PlatformIO which are great complements for [Vadim’s].

Secret Serial Port for Arduino/ESP32

If you use the Arduino IDE to program the ESP32, you might be interested in [Andreas Spiess’] latest video (see below). In it, he shows an example of using all three ESP32 UARTs from an Arduino program. He calls the third port “secret” although that’s really a misnomer. However, it does require a quick patch to the Arduino library to make it work.

Just gaining access to the additional UARTs isn’t hard. You simply use one of the additional serial port objects available. However, enabling UART 1 causes the ESP32 to crash! The reason is that by default, UART 1 uses the same pins as the ESP32 flash memory.

Luckily, the chip has a matrix switch that can put nearly any logical I/O pin on any physical I/O pin. [Andreas] shows how to modify the code, so that UART 1 maps to unused pins, which makes everything work. it is a simple change, replacing two parameters to a call that — among other things — maps the I/O pins. You could use the technique to relocate the UARTs to other places if you choose.

If you want to learn more about the ESP32, we covered a good set of tutorials for you to check out. Or if you just want a quick overview, you can start here.

Another Arduino Compatible? This Time, It’s A Sony

When it comes to microcontroller development boards, we have a plethora of choices at our disposal. Each has its strengths and weaknesses, be they associated with its support and community, its interface capabilities, or its choice of processor family. Most boards you’ll find in our communities come from niche manufacturers, or at least from manufacturers who started as such. Just occasionally though along comes one whose manufacturer you will have heard of, ever whose manufacturer the Man in the Street will have heard of.

Which brings us neatly to today’s story, the quiet announcement from Sony, of a new microcontroller development board called the Spritzer. This is Arduino compatible in both physical footprint and IDE, is intended for IoT applications, and packs GPS, an audio codec, and an ARM Cortex M4 at 156 MHz. There is a Japanese page with a little more detail (Google Translate link), on which they talk about applications including audio beam forming with up to eight microphones, and a camera interface. 

The board is due to be available sometime early next year, and while it looks as though it will be an interesting device we’d sound a note of caution to Sony. It is not good enough to have an amazing piece of hardware; the software and community support must be more than just make-believe. If they can crack that then they might just have a winner on their hands, if they fail to make any effort then they will inevitably follow Intel into the graveyard of also-ran boards.

Thanks [Chris] for the tip.
